IBM Flex System Storage Expansion Node

IBM Flex System Storage Expansion Node

IBM Redbooks Product Guide

The IBM® Flex System™ Storage Expansion Node is a locally attached storage node that is dedicated

and directly attached to a single half-wide compute node. The Storage Expansion Node provides storage

capacity for Network Attach Storage (NAS) workloads, providing flexible storage to match capacity,

performance, and reliability needs.

Ideal wokloads include distributed database, transactional database, NAS infrastructure, video

survellance and streaming solutions.

Figure 1 shows the IBM Flex System Storage Expansion Node attached to an IBM Flex System x240

Compute Node.

Did you know?

The Storage Expansion Node adds 12 drive bays to the attached compute node and all bays in the

expansion node are hot-swap. The drive bays slide out on an internal rail system; provided that a suitable

RAID level is employed, a failed drive can be removed while the system is still running. With storage

capacity of up to 12 TB, the Storage Expansion Node is ideal for applications that can use large amounts

of additional local storage.
