Internal disk storage options

The x222 has two 2.5-inch simple-swap drive bays that are accessible from the front of the unit (Figure 2),

with one bay for each of the servers. Each server offers a 6 Gbps SATA controller that is implemented by

the Intel C600 chipset. As of Flex System code base 1.3.2 (announced May 13, 2014), the ServeRAID

C100 embedded RAID controller is enabled which provides firmware-based RAID capabilities.

The 2.5-inch drive bays support SATA hard disk drives (HDDs) or SATA solid-state drives (SSDs). Each

server in the x222 optionally supports 1.8-inch SSDs by first installing the Flex System SSD Expansion

Kit in to the 2.5-inch bay. This kit then provides two 1.8-inch hot-swap drive bays.

The ServeRAID C100 is an integrated SATA controller with RAID capabilities. When enabled in a server

in the x222 with two 1.8-inch SSDs, the RAID-1 feature of the C100 offers a cost-effective way to provide

fault-tolerant disk subsystem management to help safeguard your valuable data and enhance availability.

The ServeRAID C100 has the following specifications:

Supports RAID levels 0, 1



Supports 3 Gbps SATA ports



Support for up to two virtual drives



Support for virtual drive sizes greater than 2 TB



Fixed stripe unit size of 64 KB



Support for MegaRAID Storage Manager management software



The storage configurations on the two servers in the x222 can be different, however for factory orders, the

initial storage configuration selected must be identical.

The following table lists the supported drives.
