EMC

Data Center Storage and Replication

EMC

Limited bandwidth, high latency, and dropped and out-of-order packets can slow data replication across a WAN to a crawl, or prevent it from happening entirely. EMC uses Silver Peak replication acceleration to address these issues, enabling more data to be transferred in less time between geographically dispersed locations.

Silver Peak appliances prevent transfer times from falling behind cycle times and eliminate the need to spend significant amounts on WAN bandwidth to accommodate peak workloads. As a result, the combined EMC/Silver Peak solution is essential for enterprises with stringent Recovery Point and Time Objectives (RPO/RTO).

Joint Benefits

  • Meet Recovery Point Objectives (RPO) – Replicate more data in less time to remote offsite locations.
  • Replicate over longer distances - Eliminate distance limitations between source/target devices.
  • Improve business continuity – Maintain redundant data center(s) for hot failover.
  • Lower disaster recovery costs - Eliminate costly dedicated networks for replication and avoid bandwidth upgrades.

  • Bandwidth congestion, latency, and dropped packets are all common challenges associated with replicating data between storage systems across an IP Wide Area Network (WAN). Any one of these problems can impede the replication process or prevent it from happening entirely. These issues can also increase WAN infrastructure costs and have a significant impact on the total cost of ownership (TCO) for offsite data protection.

  • EMC Data Domain deduplication storage systems optimize storage efficiency through the use of deduplication and compression of data at rest. When the deduplicated and compressed data is replicated using Data Domain, it is a common belief that WAN optimization is not required because a smaller amount of data is being sent across the WAN. However, in addition to limited bandwidth, at least two factors can affect the ability for replication to meet customer RPOs over a Wide Area Network (WAN): replication distance (latency) and quality of the WAN itself (packet loss and out of order packets). By solving many of the underlying network problems that plague EMC Data Domain and Silver Peak Integration Guide 5 replicating over distance, Silver Peak VXOA, when combined with EMC Data Domain Replicator, enables customers to move more data, over a longer distance, and in less time. In this paper we will describe the benefits that Silver Peak’s Virtual Acceleration Open Architecture, VXOA, provides for the Data Domain system; provide deployment and configuration examples; detail best practices; and illustrate expected performance improvements based on a customer deployment.

  • EMC® Isilon® enables enterprises to aggregate Big Data onto a single, shared, easy-to-use Network Attached Storage (NAS) platform. But when large amounts of data must be moved or replicated between geographically separated locations—and if these centralized applications must be accessed by remote users—challenges often arise due to poor Wide Area Network (WAN) performance. Limited bandwidth, long distances, and poor network quality can all take a toll on application performance, resulting in missed Recovery Point Objectives (RPO), excessive IT costs, and unhappy end users.

  • The EMC Symmetrix Remote Data Facility / Asynchronous (SRDF/A) is a key component for disaster recovery with EMC Symmetrix storage arrays. SRDF/A provides the technology necessary to replicate large amounts of data between geographically separated data centers. SRDF/A throughput can be severely limited by problems with the WAN connection between the primary and secondary data centers. Limited bandwidth, latency, dropped packet, and out-of-order packets all reduce SRDF/A throughput, causing missed recovery point objectives (RPO) and failed replication.

  • EMC VPLEX removes physical barriers and enables users to access a single copy of data at different geographical locations. The result is geographically stretched virtual and physical host clusters. However, certain conditions on the WAN including limited bandwidth, high latency (due to distance), and unpredictable packet delivery due to congestion may have an adverse impact on VPLEX across a Wide Area Network (WAN).
