1.1.3 ExaSAN A12S2-PS Components and Accessories
This section provides detailed description of each system component and accessory.
1.1.3.1 ExaSAN PCIe RAID Disk System
The A12S2-PS is a 2U rack mounted RAID system supporting up to 12 hot swappable
hard drives (sold separately).
Also note that the RAID disk system comes with a chassis, RAID controller, and disk trays
only. The hard disk drives (HDDs) are not included. See Section 1.1.3.2 for considerations
concerning HDDs.
Further note that a QSFP Host Bus Adapter is packaged with the PCIe RAID system. In a
DAS (Direct Attached Storage)/SAN (Storage Area Network) configuration, this card is
to be installed in the host system to provide the PCIe interface with the RAID system.
1.1.3.2 Hard Disk Drive (HDD) for the RAID System
This component is ordered separately from a third-party vendor. The quantities depend
on the number and model of RAID systems you have. Consult your RAID system User
Guide for additional information.
Hard disk drives come in different storage capacities performance levels. However, be
aware that all hard drives in a RAID system should match in size and speed.
Furthermore, all hard drives in an array should be of identical model with the same
firmware version.
Accusys recommends the SAS and SATA Enterprise HDDs for your RAID disk systems.
1.1.3.3 ExaSAN QSFP Host Bus Adapter (ACS-63200NT)
Make sure that each client system in your workgroup has an available PCIe x4, x8, or
x16 slot. Note that the PCIe slots on some motherboards are for graphics cards only.
Check your motherboard documentation or verify with the motherboard vendor for
compatibility with the Accusys-supplied HBA. Also note that some PCIe x4 or x8 slots only
