What Is an IP-SAN?
An IP-SAN is a storage area network that uses standard Ethernet/IP networking to connect servers to shared block storage. Many IP-SAN systems use iSCSI to deliver SAN-style storage without Fibre Channel complexity.
Simple Explanation
An IP-SAN lets multiple servers access centralized storage across an IP network. Instead of every server depending only on its own internal drives, storage can be consolidated into a dedicated storage system and presented to servers as block-level storage.
Why Businesses Use IP-SAN
- Shared storage for virtualization hosts
- Centralized storage for business applications
- Backup repositories and recovery targets
- Lower-cost SAN architecture using Ethernet
- Flexible expansion as capacity requirements grow
Design Still Matters
The network, switches, drives, RAID level, controller, workload, and backup strategy all affect the final result. Buying a box is not the same as designing a storage system.
