Storage Virtualization Platform: Simplifies storage complexity by providing the foundation for getting the storage an application needs, when they need it, and where they need it. High Availability: Ensures continuous availability for mission-critical applications with high expectations of service. With “quick” recovery of applications and data now measured in seconds/minutes rather than hours/days, availability must be pervasive throughout the data center. Constrained budgets to do so means increased automation and unified management of complex and distributed resources. Data Protection: Provides simple and consistent tools to protect and recover information across highly diverse storage. The integrity of corporate data is protected across all platforms and databases. Storage Area Networks (SANs): Builds on Storage Virtualization Platform to bring storage online wherever it lives across silos in the data center. It does so with accountability of storage service to the application that needs it. Disaster Recovery: Business growth requires delivering usable information at the right place at the right time. When unplanned disasters strike, firms must plan for survival of its key corporate assets – its data. Disaster recovery strategies include synchronized replicas of vital applications data and contingency planning to resume business quickly. VERITAS Services and Support facilitate the adoption and deployment these solutions with focused assessment, design, implementation, and launch services, and a worldwide support organization to provide follow-the-sun customer support. Slide Transition: So where do these solutions work? What products enable them? If you look at current market valuations, you'll find VERITAS is the fourth largest software company. Now this may well be a surprise to many of you. VERITAS is extremely well positioned and is extremely successful as a company. Since VERITAS is such a valuable company, what does VERITAS bring to IT departments that can justify such a high valuation? If you look at most IT shops, this is what they look like. Lots of storage, lots of servers, lots of vendors. Even if we consolidate down to three storage vendors, three server vendors, three operating systems, you've still got many, many permutations of that infrastructure. What we think VERITAS can do with its heterogeneous software is really enable this utility model by masking the complexities of that infrastructure. While this sounds like a terrible thing, actually, it can be useful. By keeping a heterogeneous environment, you can eliminate vendor lock in and have a choice of platforms.   VERITAS layers on top of the servers and storage to mask the complexities associated with the different operating systems and the different operating environments and presents this virtualized pool of storage and servers up to the application.   For business applications to be able to take maximum advantage of the infrastructure purchased, heterogeneous software is important. IT managers are not going to throw out their entire data center and buy a Sun data center or an HP or an IBM data center. They're going to go from where they are today to where they need to go. VERITAS is a key enabler because it's the only software provider that has heterogeneous solutions. We work with exactly what you have today, and we'll take you where you want to go. So this is the typical data center. Windows, AIX, Linux, Solaris, HP, EMC, Sun, Hitachi gear. A mixture of storage and servers throughout the organization. VERITAS can enable you to turn your IT department into a utility by [ Hit space bar ] Discovering storage resources, pooling them to improve utilization and automatically provisioning them to applications Discovering server resources, pooling them to improve utilization and automatically provisioning them to applications [ Hit space bar ] Protecting applications from hardware failure, software failure or natural disaster Monitoring performance 24x7 and fixing problems before the end users notices Supporting all major hardware and software vendors Virtualization has been around since mainframes – takes storage resources and turns them into something useful to users. Having said that, virtualization is now available in the storage array, the intelligent switch and the server itself. So, where does VERITAS recommend performing virtualization? Everywhere. INTELLIGENT ARRAY Array vendors typically recommend LUN sizes that are optimized for performance. So, it’s good to “virtualize” the disks into LUNs for performance. However, these LUNS are typically too large to partition for optimal utilization. For example, EMC recommends 160GB LUNs. Therefore, use the…: INTELLIGENT NETWORK Here, aggregate your array management. Control all copy services from a single console. Bring other non-intelligent disks into the SAN and give them intelligence with virtualization in the switch. Finally….: HOST Use the host to provide polices and active management on top of the virtualization that has occurred in the switch and the network. FOR EXAMPLE HOST: File System Polices, Write Tuning, Multi-pathing SWITCH: Snapshots, Aggregated Array Management ARRAY: RAID for Performance So, knowing that, let me explain how VERITAS Packages our storage virtualization and management products. We have a core file system and volume manager. We then take those two products, add some important features to them and repackage them as VERITAS Storage Foundation. Then, we take Storage Foundation and optimize it for specific database environments. This package is called VERITAS Storage Founation for Databases. Finally, we offer certain virtualization services that run on an intelligent network switch. This product is known as Storage Foundation for Networks. Finally, let’s talk about how you can double your Storage Utilization with Storage Foundation. Let's drill down a second on availability of data. Organizations need to consider recovery point and the recovery time objectives when thinking about data and data protection. This is how much data can you afford to lose, and how long can you afford to be down. Once that decision has been made, you're very well positioned to choose which technology is going to be most useful to solve your problems. Depending on how your recovery point or recovery time look, you can select many different kinds of technologies from VERITAS. You might decide that the application can withstand hours, or even days, of downtime, so a very simple tape based backup solution might be enough for you. You may also decide that you've got a highly transactional mission-critical application, maybe it's an online web site or maybe it's a trading floor, so you can only withstand minutes, or even seconds, of downtime. To meet this demand, you might choose a very highly available clustered and replicated solution, so that no matter what happens, you can be taking transactions within seconds of the failure. The good news is that VERITAS offers a complete suite of software that can provide both -- an environment which can get by with hours or days of downtime, or an environment that gets up and running within minutes or even seconds. So whatever you decide, VERITAS has a solution. The type and level of data protection required for a business depends primarily on the size of the organization, the amount of data, the rate of data growth, and how business-critical the applications are. Workgroup Environments Workgroup-class environments generally have a viable backup window with fewer systems and relatively small amounts of data to backup. Such environments have a reasonable tolerance for downtime and can sustain the effects of some data loss. Applications in these environments can be brought offline, and cold backups of data can be performed with little or no effect on business productivity. A workgroup-class business can deploy a basic offline backup and recovery strategy. This strategy can be supplemented with RAID and dynamic multipathing to make data highly available against hardware failures in components such as disk drives, host bus adapters and cables. Mission-Critical Workgroup Environments The transition of a workgroup business environment into a mission-critical environment mandates the need to reduce or eliminate downtime and deliver fast recovery in case of disruptions. Backup and maintenance windows for the mission critical operations of the business are zero or close to zero, and performance along with data currency becomes important. Mission-critical applications require online backups of open files, and demand a higher level of data protection against unforeseeable disruptive events. Technologies, such as mirroring, point-in-time data copy with fast resynchronization capabilities, and replication in conjunction with tape backups, deliver effective and efficient data protection solutions for this environment. Enterprise Environments Enterprise environments have large amounts of data spread across a number of systems and sites, making effective backup windows small and requiring centralized online backups and restores. System performance becomes important, as there are multiple applications competing for the same resources. Sharing of these valuable resources for non production tasks, such as backups and restores, penalizes production performance. Deploying technologies that effectively use system resources can greatly reduce the overall cost outlay for an enterprise. Combining technologies like global data management, replication, mirroring, point-in-time data copy, LAN-free backups, and hierarchical storage management, can create the right enterprise-class data protection solution. Mission-Critical Enterprise Environments Mission-critical enterprise environments have the most stringent data availability, performance and protection requirements. These environments have zero tolerance for downtime and data loss. Offline backup and restore windows are nonexistent making online, virtual backups and restores the only feasible data protection solution. Technologies that offer extremely quick and simple recovery, such as bare metal restore, non intrusive data protection like LAN-free and server-free backups, off-host backups and vaulting, logical volume split and join, and online replication are best-suited for mission-critical enterprise environments. These technologies coupled with other cutting edge data protection technologies, like frozen image, incremental point-in-time data, hierarchical storage management, mirroring, and multipathing, offer the top-of-the-line data protection solutions. As we move into the enterprise class space, VERITAS offers VERITAS NetBackup Enterprise Server. This product provides a very flexible and easy to use centralized management interface that is able to backup and recover UNIX, Windows, Linux, and Netware systems, as well as a variety of other operating systems. In the diagram, NetBackup Enterprise Server offers a very flexible tiered architecture consisting of a master server, the media server, and the clients that it's protecting. This enables the business to basically have one solution for their entire IT environment and their backup and recovery needs. NetBackup Enterprise Server offers centralized management, in other words, management from one console, and is flexible architecture that can be mixed and matched in a variety of ways. Enterprise Server also supports the most popular operating systems, databases and storage hardware currently available on the market. All data is not created equally and the criticality of data changes over time. Email is often most useful when received and quickly loses value, whereas financial data may have more cyclical criticality. DLM enables companies to automatically move data to appropriate resources as these changes take place. . When a file has not been accessed in 90 days, it moves from the online disk to near line storage; then after 1 year of no access, it moves from nearline to tape. VERITAS delivers the technology that you will need to protect your organization’s data. Some additional facts you should be aware of are as follows: Industry’s Broadest Support Applications: Oracle,SAP, Exchange, SQL, SharePoint Portal, DB2, Sybase, Informix, Lotus Platforms: Windows, UNIX, LINUX, NetWare Tape and Disk Storage Storage Networking No Proprietary Hardware Lock-In Extensive Qualification and Joint Support For more detail: • Comprehensive Technology — VERITAS is the only company that can provide a complete range of data protection technology from offline data protection through online data protection to the latest innovations that merge offline and online technologies. • Broad Platform Support — VERITAS supports an extremely broad range of operating systems, platforms, arrays and tape libraries to ensure that you can create a consistent backup and recovery policy across your enterprise. • Protects the Entire Environment — VERITAS’ best-of-breed data protection technology provides support for your entire environment – from the desktop to the data center to laptops and mobile devices. The first product that I'd like to discuss is VERITAS Cluster Server.   VERITAS Cluster Server assists in keeping applications and databases highly available. The way that Cluster Server works is that it detects a failure, and automatically transfers services to another available working server in order to reduce the downtime of that service. The key benefits that VERITAS Cluster Server provides are three key areas. First and foremost, automation. VERITAS Cluster Server can failover based on applications. So, if a single application within a server fails, it will automatically failover to another available working server. Second, VERITAS Cluster Server is an open solution. It supports the most extensive hardware, storage, and applications on the market today. VERITAS Cluster Server provides the same management across all open systems. That means if you're running Solaris, HP, AIX, Windows, or Linux, you can use the same technology across the board and the administrators will know the technology no matter what operating system they are running. Finally, VERITAS Cluster Server is a robust technology. It is the #1 clustering product in UNIX today. And it is highly scalable, meaning that you can scale up to 32 nodes within a single cluster. To summarize, VERITAS Cluster Server is available to keep applications and databases highly available and to reduce the downtime of databases and applications. Key Message: It is important for companies to have the flexibility to scale from local high availability to disaster recovery. VERITAS provides a solution that can scale from LAN, MAN and WAN as simple as turning on license keys. Integration between Storage Foundation and Cluster Server ensures not only data is protected in the event of an outage but also applications are kept running. With a single solution, VERITAS Cluster Server, a company can provide high availability to applications in a single datacenter to providing disaster recovery over wide area. With VERITAS Storage Foundation, Data can be protected either within a single storage array to providing disaster recovery and data protection over a wide area using IP. It’s as simple as that! ****************************************************************************** More information on what each configuration provides and the Advantages and Disadvantages of each: Local Clustering Shared-storage clusters are considered second generation clusters, and today are the most prevalent (over shared-nothing) for providing HA through application failover, primarily for RDBMS applications, ., Oracle, DB2, Sybase, etc.   Questions to ask your customer to see if this infrastructure is appropriate for their environment: Do you have a storage area network (SAN) infrastructure? Is your data center in one location or are other components if your data center in another location near campus or off site? Are you satisfied with local availability? Architectural characteristics of this configuration include:  A redundant server, network and storage architecture for application and data availability through the linking of multiple servers with shared storage; Systems are linked with private heartbeats, usually ethernet, which they use to communicate state status – VCS uses a fast proprietary protocol, GAB/LLT, to communicate status; Each system in the cluster can access the storage of any other system. There is no replication or mirroring of data, as opposed to a shared-nothing or stretch cluster A SAN facilitates larger clusters (> 2 nodes), and is typically present in all clusters, ., switches or hubs are used; All cluster components – servers, SAN infrastructure, storage – are co-located on a single site. What products can be offered to support this solution? VCS and Storage Foundation  Advantages Applications can be easily migrated from one server in the cluster to any other server, facilitating application uptime. Redundant components prevent single point of failure; Use of SAN enables data access and sharing; Disadvantages Complexity Cost ********************************************* Metro DR with Remote Mirroring This architecture typically gets deployed when customers want DR over short distances, and they have a SAN infrastructure in place. Many VERITAS customers in the Wall Street area have set up campus clusters with VM mirroring to separate their data centers over several miles, thus providing DR against such disasters as terrorist attacks. This would not provide long distance DR against a natural disaster such as an earthquake. Characteristics include: Single VCS cluster spanning multiple locations Can have multiple VCS nodes at each site (2 sites maximum) Uses VxVM to create a mirror with plexes in two locations No host or array replication involved With new data switches using DWDM, support for up to 100KM distances have been claimed. VCS is testing with some of these. Requires Professional Services to Implement Separation Range dependent on infrastructure provider   What products can be offered to support this solution? Storage Foundation and Cluster Server (or any 3rd party array vendor that provides data mirroring) Advantages: ·        Effective configuration for Disaster Recovery at a low cost ·        Quick restore in the event of a disaster (remote mirroring is quick – always in synch) ·        Maximum use of infrastructure – effective use of fibre infrastructure that company already has in place. ·        Most disasters are localized and this configuration would protect against most disasters.   Disadvantages: Complexity Cost of DWDM/Fibre infrastructure. The key to this architecture slide is to emphasize that a customer who purchases Volume Manager and Cluster Server (or Foundation Suite/HA) can achieve local availability as well as metropolitan disaster recovery for no additional costs. Metropolitan Disaster Recovery (also known as Campus Clustering or Stretch Clustering) has been a prominent deployment for several companies who’s service level agreements don’t require a disaster recovery site to be across the country. Rather than investing in a disaster recovery site thousands of miles away, a customer can invest in a disaster recovery data center in the same city. The cost savings are tremendous! The minimal requirements is that the customer has a SAN infrastructure. The distance limitations depend on the latency that the customer is willing to afford. VERITAS recommends within 100 km. Remote Mirroring technology found in Volume Manager is used to replicate the data between the two sites synchronously. If the customer has already purchased Volume Manager and Cluster Server, this is a bonus that is part of the feature set. A customer example using metropolitan disaster recovery is a large bank in NYC who has fiber under the Hudson. Their remote site is in New Jersey. This is sufficient to meet their disaster recovery needs at an affordable price. *************************************************************** Metro DR with Replication Metro DR with Replication is a VCS, shared nothing configuration using replication between nodes to allow geographical separation of the cluster, thus providing both HA and DR benefits. Due to latency, the separation permitted will not be as extensive as a wide-area, TCP/IP solution, but RDC does provide a straight-forward, single cluster solution for many DR scenarios. The replication must be synchronous. Currently, VVR and SRDF replications are supported. The solution supports a cluster with 32 nodes. X number of nodes can be at the primary site, Y nubmer of nodes at the secondary site. In the event of a failure, VCS will attempt to failover the service group on a node at the primary site first before failing over to the remote site. A question associated with this architecture is when to position it over the campus cluster solution with VM mirroring. The general rule is that if a customer does not want to invest in a SAN, they can just run private Ethernet networks for VCS heartbeating, and set up Metro DR with Replication. If the customer has a SAN infrastructure in place, they would implement Metro DR with Remote Mirroring.   This configuration is supported with VVR, SRDF and True Copy in a Solaris environment and SRDF only in a Windows environment. There are distance limitations to this configuration. Distance can be greater than a campus cluster architecture but less than DR (WAN) architecture. This is due to LLT (heartbeat) connections. This configuration can be stretched as far as the network latency for LLT is acceptable. This generally means no more than 500ms (1/2 second) return trip response between the two sites. ********************************************************** Wide Area Disaster Recovery GCM is both a management solution and a DR solution, involving multiple VCS clusters. Of the HA and DR solutions offered by VERITAS, it is the only one which involves multiple clusters. The stretch clusters use multiple sites, but always a single cluster. GCM is used for DR where unlimited geographical separation is called for, or for when management from a single console is needed to manage an enterprise’s clusters worldwide.   The management solution (Base Option) does not implement replication. The DR option, which builds on the Base Option, always uses replication, either host-based from VERITAS, or array based, from 3rd party vendors like EMC (SRDF), or HDS (TruCopy).   Advantages: Can support any distance Multiple replication solutions Multiple clusters Multiple OSes   Disadvantages: Cost Complexity Not integrated with VCS.   VERITAS’ portfolio of Intelligent Storage Software solutions empower users to design an Availability strategy that meets the level requirements of the customer and market opportunity.

VERITAS Volume Replicator is based on the exact same code base as VERITAS Volume Manager and is the IP option to Volume Manager. Volume Replicator allows data to be replicated between any storage device over a standard IP network across any distance in order to minimize or eliminate data loss should an outage occur. The three key benefits that Volume Replicator provides is first, cost savings. Because Volume Replicator replicates at the logical volume level, it allows you to replicate data between any storage device. This means you don't have to have the same array at both your primary and secondary locations. This allows customers to save money when they're implementing replication technologies. In addition, Volume Replicator replicates over an IP network natively. This means you do not need any specialized networking gear in order to replicate over IP, which provides a substantial cost savings when implementing replication. In addition, customers do not need to worry about managing additional hardware in order to replicate over IP. The next thing that Volume Replicator provides is protection. It offers uncompromised data integrity in both synchronous and asynchronous mode, meaning when you replicate with Volume Replicator, you can be assured that you will have absolutely no windows of data corruption. Volume Replicator has full database support, and it's going to protect customers against network outages. If a network failure occurs, Volume Replicator can continue to track writes at the primary site. When the network comes back online, all it does is ship the changes over the wire. This is going to protect environments from network outages. Finally, Volume Replicator provides the ability to get the secondary site up and running quickly. You can either send all of your data over the wire, or you can do a tape based initialization approach, allowing you to bring up the secondary site by using a tape back-up strategy. This is going to allow you to get your secondary site up and running faster and more cost effectively without forcing the customer to send all the data over the wire or ship storage arrays to the secondary site.. Key Message: It is important for companies to have the flexibility to scale from local high availability to disaster recovery. VERITAS provides a solution that can scale from LAN, MAN and WAN as simple as turning on license keys. Integration between Storage Foundation and Cluster Server ensures not only data is protected in the event of an outage but also applications are kept running. With a single solution, VERITAS Cluster Server, a company can provide high availability to applications in a single datacenter to providing disaster recovery over wide area. With VERITAS Storage Foundation, Data can be protected either within a single storage array to providing disaster recovery and data protection over a wide area using IP. It’s as simple as that! ****************************************************************************** More information on what each configuration provides and the Advantages and Disadvantages of each: Local Clustering Shared-storage clusters are considered second generation clusters, and today are the most prevalent (over shared-nothing) for providing HA through application failover, primarily for RDBMS applications, ., Oracle, DB2, Sybase, etc.   Questions to ask your customer to see if this infrastructure is appropriate for their environment: Do you have a storage area network (SAN) infrastructure? Is your data center in one location or are other components if your data center in another location near campus or off site? Are you satisfied with local availability? Architectural characteristics of this configuration include:  A redundant server, network and storage architecture for application and data availability through the linking of multiple servers with shared storage; Systems are linked with private heartbeats, usually ethernet, which they use to communicate state status – VCS uses a fast proprietary protocol, GAB/LLT, to communicate status; Each system in the cluster can access the storage of any other system. There is no replication or mirroring of data, as opposed to a shared-nothing or stretch cluster A SAN facilitates larger clusters (> 2 nodes), and is typically present in all clusters, ., switches or hubs are used; All cluster components – servers, SAN infrastructure, storage – are co-located on a single site. What products can be offered to support this solution? VCS and Storage Foundation  Advantages Applications can be easily migrated from one server in the cluster to any other server, facilitating application uptime. Redundant components prevent single point of failure; Use of SAN enables data access and sharing; Disadvantages Complexity Cost ********************************************* Metro DR with Remote Mirroring This architecture typically gets deployed when customers want DR over short distances, and they have a SAN infrastructure in place. Many VERITAS customers in the Wall Street area have set up campus clusters with VM mirroring to separate their data centers over several miles, thus providing DR against such disasters as terrorist attacks. This would not provide long distance DR against a natural disaster such as an earthquake. Characteristics include: Single VCS cluster spanning multiple locations Can have multiple VCS nodes at each site (2 sites maximum) Uses VxVM to create a mirror with plexes in two locations No host or array replication involved With new data switches using DWDM, support for up to 100KM distances have been claimed. VCS is testing with some of these. Requires Professional Services to Implement Separation Range dependent on infrastructure provider   What products can be offered to support this solution? Storage Foundation and Cluster Server (or any 3rd party array vendor that provides data mirroring) Advantages: ·        Effective configuration for Disaster Recovery at a low cost ·        Quick restore in the event of a disaster (remote mirroring is quick – always in synch) ·        Maximum use of infrastructure – effective use of fibre infrastructure that company already has in place. ·        Most disasters are localized and this configuration would protect against most disasters.   Disadvantages: Complexity Cost of DWDM/Fibre infrastructure. The key to this architecture slide is to emphasize that a customer who purchases Volume Manager and Cluster Server (or Foundation Suite/HA) can achieve local availability as well as metropolitan disaster recovery for no additional costs. Metropolitan Disaster Recovery (also known as Campus Clustering or Stretch Clustering) has been a prominent deployment for several companies who’s service level agreements don’t require a disaster recovery site to be across the country. Rather than investing in a disaster recovery site thousands of miles away, a customer can invest in a disaster recovery data center in the same city. The cost savings are tremendous! The minimal requirements is that the customer has a SAN infrastructure. The distance limitations depend on the latency that the customer is willing to afford. VERITAS recommends within 100 km. Remote Mirroring technology found in Volume Manager is used to replicate the data between the two sites synchronously. If the customer has already purchased Volume Manager and Cluster Server, this is a bonus that is part of the feature set. A customer example using metropolitan disaster recovery is a large bank in NYC who has fiber under the Hudson. Their remote site is in New Jersey. This is sufficient to meet their disaster recovery needs at an affordable price. *************************************************************** Metro DR with Replication Metro DR with Replication is a VCS, shared nothing configuration using replication between nodes to allow geographical separation of the cluster, thus providing both HA and DR benefits. Due to latency, the separation permitted will not be as extensive as a wide-area, TCP/IP solution, but RDC does provide a straight-forward, single cluster solution for many DR scenarios. The replication must be synchronous. Currently, VVR and SRDF replications are supported. The solution supports a cluster with 32 nodes. X number of nodes can be at the primary site, Y nubmer of nodes at the secondary site. In the event of a failure, VCS will attempt to failover the service group on a node at the primary site first before failing over to the remote site. A question associated with this architecture is when to position it over the campus cluster solution with VM mirroring. The general rule is that if a customer does not want to invest in a SAN, they can just run private Ethernet networks for VCS heartbeating, and set up Metro DR with Replication. If the customer has a SAN infrastructure in place, they would implement Metro DR with Remote Mirroring.   This configuration is supported with VVR, SRDF and True Copy in a Solaris environment and SRDF only in a Windows environment. There are distance limitations to this configuration. Distance can be greater than a campus cluster architecture but less than DR (WAN) architecture. This is due to LLT (heartbeat) connections. This configuration can be stretched as far as the network latency for LLT is acceptable. This generally means no more than 500ms (1/2 second) return trip response between the two sites. ********************************************************** Wide Area Disaster Recovery GCM is both a management solution and a DR solution, involving multiple VCS clusters.
