Maximum logical drive capacity supported on Intel SAS RAID controllers

Intel SAS RAID or embedded controllers in Intel 5000 series, Intel S3200/S3210 and Intel® Server Boards with the Intel® X38 Express Chipset currently use two 64 bit memory addressing. This provides for the capability of supporting greater than 2 Terabytes (TB) logical drive capacity (up to 16 Exabytes).

For example, with SAS controllers you could have 10 TB of physical disks configured in an array and have one 10 TB logical drive if you wanted.

With logical drive capacities this large, not all operating systems may support these sizes. Contact your operating system vendor to determine the logical (raw) drive size supported by your operating system.

Maximum physical drive capacity supported by Intel® Server Boards or Intel® RAID Controllers can be limited by controller hardware.

RAID Controller Supported Logical Drive Capacity
ESRT2 <= 2 TB
LSI 1068 <= 2 TB
LSI 1078 <= 2 TB
LSI 2108 and 2008 > 2 TB
LSI 2208 and 2308 > 2 TB
LSI 3008 > 2 TB
LSI 3108 > 2 TB
Note Intel Embedded Server RAID Technology II (ESRT2) is server board host-based RAID that utilizes the chipset, processor(s), and memory of the server board to provide RAID modes 0, 1, and 10. RAID 5 is available with an optional Intel® RAID Activation Key AXXRAKSW5.
Note The Intel® RAID Controller SRCSATAWB and RT3WB080 are SATA only RAID controllers, but have the same maximum logical drive capacity.
