Unified IBM System Storage N Series N3150

System Storage N3150 Series from IBM Corp. consists of single-node (Model A15) and dual-node (Model A25) (active-active) base units.

Both models are designed to provide fast data access, simultaneous multiprotocol support, expandability, upgradability, and low maintenance.

Model 2857-A15
N3150 Model A15 is designed to provide a single-node storage controller with HTTP, CIFS, NFS, and iSCSI support via optional features. The N3150 Model A15 is a 2U storage controller that must be mounted in a standard 19-inch rack. Model A15 can be upgraded to a Model A25, however, this is a disruptive upgrade.

Model 2857-A25
N3150 Model A25 is designed to provide identical functions as the single-node Model A15, but with the addition of a second processor control module (PCM) and the Clustered Failover (CFO) licensed function. Model A25 consists of two PCMs that are designed to provide failover and failback function, helping improve overall availability. Model A25 is a 2U rack-mountable storage controller.

Key prerequisites
NFS, CIFS, or iSCSI protocol function.
