Compellent SIR


VSM LABS SCENARIO

UNDER EXAMINATION: Block-based storage virtualization

WHAT WE TESTED

Compellent Storage Center with Data Instant Replay, Server Instant Replay, and Remote Instant Replay

  • SAN software certified for ESX Server 3.x.
  • Simplify system administration through automation
  • Replays work with pointers rather than copies of data
  • Automate boot-from-SAN setup with Server Instant Replay
  • Provide a highly efficient DR solution with Remote Instant Replay

HOW WE TESTED

VMware ESX Server V3
Windows 2003 Server SP2


KEY FINDINGS

  • Replays utilize far less storage space than snapshots by preserving only pointers to blocks that have changed since a prior Replay
  • A wizard cuts configuration time for OS volume to be booted over the SAN by guiding administrators through recovering or replicating a boot volume and then mapping the new volume to a server.
  • Remote Instant Replay copies only the replicating system's actual data along with an unlimited number of replay checkpoints to minimize data loss and ensure a fast recovery time.
  • Thin Replication Improves both RPO and RTO in Disaster Recovery:
