The IBM FlashSystem 5045 NL-SAS HDD 70TB is a 2U rackmount storage array with 64GB cache, dual active/active controllers, and 12 NL-SAS hard drives; it suits businesses building shared, high-capacity SAN storage with redundant hardware and Fibre Channel or iSCSI connectivity.
Recommended For
- IT teams at small or midsize organizations that need shared block storage for several servers or virtualized workloads, and want SAN features such as dual controllers, snapshots, and replication in one system.
- Organizations building a high-capacity storage tier for large, mostly sequential data—such as repositories, backup copies, or other data that does not need all-flash response times. IBM describes NL-SAS as better suited to streaming I/O than OLTP.
- Teams that need a secondary SAN for backup or replication alongside a faster primary array, and can use the 5045’s snapshots and remote-mirroring features for recovery workflows.
- Storage administrators who want IBM Storage Virtualize capabilities—such as thin provisioning, snapshots, encryption, and clustering—on a capacity-oriented HDD configuration rather than an NVMe all-flash array.
