Maximum Logical Drive Capacity Supported on SAS Intel® RAID Controllers
Which products use two 64-bit memory?
These products currently use two 64-bit memory:
- SAS Intel® RAID Controllers or embedded controllers in Intel® Server Board 5000 series
- Intel® Server Boards S3200/S3210
- Intel® Server Boards with the Intel® X38 Express Chipset
What does this memory enable me to do?
This memory provides for the capability of supporting greater than 2 terabytes logical drive capacity (up to 16 Exabytes).
For example, with SAS controllers you could have 10 terabytes of physical disks configured in an array and have one 10-terabyte logical drive.
What if my operating system doesn't support this size?
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. Controller hardware can limit the maximum physical drive capacity supported by Intel® Server Boards or Intel® RAID Controllers.
| Intel® RAID Controller | Supported Logical Drive Capacity |
| Intel® Embedded Server RAID Technology II | <= 2 terabytes |
| LSI 1068 | <= 2 terabytes |
| LSI 1078 | <= 2 terabytes |
| LSI 2108 and 2008 | > 2 terabytes |
| LSI 2208 and 2308 | > 2 terabytes |
| LSI 3008 | > 2 terabytes |
| LSI 3108 | > 2 terabytes |
