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:
