The IBM® System Storage® N6250 storage controllers are designed to interoperate with products capable of data transmission in the industry-standard iSCSI, CIFS, FCP, FCoE, and NFS protocols. Supported systems include the IBM eServer System p®, System i® (NFS only), System x®, and System z® (NFS only) servers.
The N6250 systems consist of Model E16 and Model E26, and associated software. All models can be configured, via optional features, to be either storage controllers or gateways. Dual-node configurations include Clustered Failover (CFO) support (via required feature), designed to provide failover and failback function, helping improve overall availability. All N6250 models must be mounted in a standard 19-inch rack. None of the N6250 models include storage in the base chassis.
See the Interoperability Matrix at the following web page for supported devices for your N series system.
