REMOTE INSTANT REPLAY

REMOTE INSTANT REPLAY STORAGE CENTER DATASHEET STORAGE CENTER REMOTE INSTANT REPLAY Business Continuance Within Reach Remote replication is one of the most frequently required, but least implemented technologies in storage environments today. With many operations running 24x7, companies understand the need for business continuance in the case of a disaster. But when it comes time to purchase and implement a solution, the cost and complexity of traditional remote replication offerings have prevented widespread use.

Ensure availability of data with an unlimited number of recovery points at multiple locations. Improve bandwidth utilization with replication link estimation and optimization. 1

Analysts agree that the largest cost associated with remote replication solutions is the recurring bandwidth costs. PRODUCT FEATURES Thin Replication: A More Efficient Replication Solution Storage Center s patented technology intelligently optimizes replication at the block-level to provide a more efficient replication solution called Thin Replication. During the initial site synchronization process, Thin Replication sends only written data instead of the allocated but unused space sent by other replication technologies. For ongoing replication, Thin Replication transfers only the changed data, consuming less space and lowering bandwidth costs. Because Thin Replication is space-efficient you can create an unlimited number of Replays and easily replicate those Replays to one or more locations. This unlimited granularity enables short recovery intervals, allowing more recovery points so you can instantly recover from any point in time.

IP-Based Replication Reduces Costs Storage Center provides architectural advantages that ensure lower costs. With a native iscsi interface, Remote Instant Replay allows replication over long distances using existing Ethernet networks. IP-based replication is easy to implement and manage, delivering business continuance without the traditional complexity and cost. To enable IP-based replication, simply connect an iscsi card directly into the controller for each system.» IP-based replication is simple to set up, uses existing networks, infrastructure and staff and does not require specialized training or scripting» Native iscsi connectivity eliminates the need for costly third-party protocol converters» Remote Instant Replay also supports traditional Fibre Channel replication 2

Bandwidth Optimization Reduces Cost and Increases Performance Remote Instant Replay s bandwidth optimization lowers transmission costs while maintaining optimal replication performance. Using Compellent s Enterprise Manager, administrators can accurately estimate bandwidth requirements upfront based on actual data, optimizing the initial bandwidth purchase. Advanced bandwidth shaping ensures the most efficient use of available bandwidth on a daily basis without forcing you to compromise on performance. Using a simple drop-down menu, administrators can optimize transfer rates on an hourly basis in the day and evening to maximize internet traffic during the day and replication traffic during off hours. To further reduce replication costs while expediting initial synchronization time, administrators can utilize Portable Volume, a replication jumpstart kit with a pair of 2 TB external hard drives preconfigured for use with the Compellent SAN.» Utilize bandwidth shaping to select replication utilization for a particular volume or set of volumes» Administrators can limit the amount of bandwidth available to each replicating volume to avoid over-consumption during peak periods and ensure fair distribution of bandwidth if multiple replications are running concurrently» Prioritize replication on a per-volume basis, assigning critical volumes priority so they are given more bandwidth and processed quickly» Available bandwidth can be metered based on line speed and time of day» Comprehensive management and monitoring features help you understand how utilization is affecting performance» Replay de-duplication ensures the same block of data is not sent twice» Choose to send individual blocks as they are changed or entire Replay when complete» Portable Volume reduces initial synchronization time from weeks or months to days without the need for expensive high-speed connections or duplicate arrays. Intelligent Bandwidth Utilization: Manage bandwidth based on line speed and time of day to ensure fair distribution and avoid over-consumption during peak periods. 3

Thin Replication ensures business continuity at a fraction of the cost of other replication solutions, cutting bandwidth and management requirements by 50%. Intuitive Interface and Online Verification Streamline Replication Storage Center s wizard-based interface sets a new standard for ease of use when it comes to replication management, scheduling and verification. Intuitive enough for any administrator to use with no training required, replication can be setup in as few as 6 clicks. Test recovery on a daily basis in just a few mouseclicks, with no impact to your operation. Enterprise Manager takes replication management a step further by consolidating system information into a single console for a complete view of your Compellent storage environment.» Setup replication in as few as 6 clicks» Easily test replication daily or even hourly without downtime, even while replication is still in progress» Create replication templates without complex scripting using drag-and-drop icons» Wizard-based setup and recovery, remote and local web-based monitoring and Phonehome status notification enable effortless management» Replays can map to any server at any time» Once Replays reach user-defined expiration, Storage Center automatically returns the available space to the storage pool Effortless Management and Verification: Easily manage and verify replication at multiple sites with a centralized point-and-click interface. 4

Multi-Site Replication Enables Robust and Reliable Data Protection With Remote Instant Replay, unlimited Replays deliver advanced replication capabilities, allowing a business the flexibility to establish multiple locations as recovery points. Any number of locations can actively and simultaneously replicate to a single primary location or to each other, without the need and expense of a dedicated site with duplicate configurations. For example, the primary site could consist of high-performance Fibre Channel drives while a remote location is configured with lower-cost SATA drives. What s more, a single volume can span both Fibre Channel and SATA drive types.» Create remote copies automatically and simultaneously to multiple sites with different configurations, reducing dependence on traditional tape backup strategies for recovery» In bi-directional replication configurations, each location can have it s own Replay schedule» Replication can be enabled in bi-directional point-to-point or multi-point configurations» Replication can be synchronous (short distance) or asynchronous (long distance)» All sites are active and available, reducing time to recovery Local Storage System WAN Remote Site 1 Remote Site 3 Remote Site 2 New Levels of Business Continuity: Multi-site replication enables robust data protection without the need for matching configurations at each site. The Only Enterprise Remote Replication with Thin Replication Remote Instant Replay s patented replication efficiency, consumes less space and reduces hardware, bandwidth and management costs. Thin Replication enables businesses to quickly and affordably establish disaster recovery practices with the granularity to recover to any point in time. By replicating continuous Replays between local and remote sites, businesses can implement a robust, yet cost-effective business continuity plan. Thin Replication s advanced bandwidth simulation and unique shaping algorithms optimize network utilization to meet both performance and budget requirements.
