IP SAN
Deploy an IP SAN as part of a comprehensive storage strategy in order to radically reduce overall storage costs, unify management of all storage systems and enjoy a full-featured fail-safe storage implementation.
Top 10 Reasons to Connect to Your Storage Pool over IP:
- Manage your entire storage pool from the switch including virtualization, data replication and more.
- No HBAs needed, connect as many servers as you need.
- Tier your storage - off-load non-critical applications to an IP SAN.
- Increase storage utilization to 90%.
- Virtualize your storage pool.
- Resize volumes on the fly.
- Easily archive or retire data.
- Share and control access.
- Ensure business continuity with mirroring, snapshots and sync or async local and global data replication.
- Performance equal to native FC solutions.
Best Practices for Implementation
- If server CPU utilization exceeds 50% during normal workload, 65% peak load, and/or 75% during backup or mirroring operations, then implement an iSCSI ToE NIC.
- Assuming a baseline of 50-200 IOPS for a standard business server, a 1GB connection can support 16 servers (supposing that each server is not generating more than 5MB per second of storage traffic).
- Non-blocking layer-2/layer-3 Gigabit Ethernet switches for IP Backbones are highly recommended.
- A single IP SAN switch can handle well over 100 standard business application servers, assuming all the servers do not simultaneously generate more than 5 megabytes per second and 600 IOPs.
- Use cost-correct storage. Because an IP SAN can connect to any type of storage, you can easily construct a SAN with primary, secondary and even tertiary storage for your varying application and performance needs.
