Lenovo Flex System x240 M5 Product Guide 14

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 LSI SAS3004 12 Gbps SAS/SATA

RAID-on-Chip (ROC) controller.

The integrated LSI SAS3004 ROC has the following features:

Four-port LSI SAS3004 controller with 12 Gbps throughput per port



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



The onboard 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, two 1.8-inch

bays replacing each 2.5-inch bay, by using the ServeRAID M1200 RAID 5 Enablement Kit, 00JX141. This

kit contains a replacement backplane to connect the four 1.8-inch SSDs. The kit also includes ServeRAID

M1200 Zero Cache/RAID 5 Upgrade (Feature on Demand license), which adds RAID 5 support.

The two standard 2.5-inch SAS/SATA drive bays can also be replaced with new PCIe 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.

Support for NVMe drives 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.
