Internal storage

The x240 M5 server has two 2.5-inch hot-swap drive bays that are accessible from the front of the blade server

(see

Figure

2). These bays connect to the integrated ServeRAID M1210e 12 Gbps SAS/SATA controller.

The integrated ServeRAID M1210e controller has the following features:

Based on the LSI SAS3004 RAID-on-Chip (ROC)

12 Gbps controller with four ports

PCIe x4 Gen 2 host interface

Two SAS ports routed internally to the two hot-swap drive bays

Supports RAID-0, RAID-1 and RAID-1E

Optional support for SED drives

Optional support for RAID-5 and 4x 1.8-inch drive bays

The onboard M1210e controller optionally supports self-encrypting drives (SEDs) with the addition of Features

on Demand license upgrade, ServeRAID M1200 Series Zero Cache/RAID 5 Upgrade, 00AE930. This license

upgrade enables the LSI MegaRAID SafeStore service which offers instant secure erase and local key

management for SEDs.

The two 2.5-inch front-accessible drive bays can be replaced with four 1.8-inch drive bays by using the

ServeRAID M1200 RAID 5 Enablement Kit (00JX141). This kit contains a replacement backplane to connect the

four 1.8-inch SSDs, however, to enable RAID 5 you will also need the ServeRAID M1200 Series Zero

Cache/RAID 5 Features on Demand upgrade (00AE930).

The two standard 2.5-inch SAS/SATA drive bays can also be replaced with new NVMe (Non-Volatile Memory

Express) drives that are directly connected to the PCIe bus of the second processor. Such connectivity, when

combined with SSD drives, ensures the lowest possible latency while still using a standard drive form factor.

2nd processor required : Support for NVMe PCIe SSDs requires a replacement drive backplane for the two

2.5-inch drives, plus the second processor must also be installed in the server. The kit containing the backplane,

NVMe Enterprise PCIe SSD Enablement Kit for Flex System x240 M5, is listed in the following table. The

second processor is ordered separately.

ServeRAID M5215 SAS/SATA controller

The ServeRAID M5215 SAS/SATA controller is an advanced RAID controller based on the LSI SAS 3108

chipset. The M5215 replaces the onboard SAS controller in the compute node and supports high-performance

RAID-0 and RAID-1 to the two internal 2.5-inch drive bays. The M5215 is installed at the front of the server over

the top of the drive bays, as shown in the following figure.

Note: The use of the ServeRAID M5215 requires that the second processor be installed.
