HP PCIe IO Accelerator for ProLiant Servers

Introduction 6
 Microsoft Windows 2008 Server 64-Bit, R1 (with SP2 or higher)
 Microsoft Windows 2008 Server 64-Bit, R2
NOTE: All operati
ng systems must be 64-bit architecture to support the PCIe IO Accelerator.
Running the latest Service Pack of a release is strongly recommended.
Hardware Requirements
The PCIe IO Accelerator requires at least:
 An open PCI-Express slot. The PCIe IO Accelerator requires a minimum of a half-length,
half- height slot with an x4 physical connector. All four lanes must be connected for full
performance. The PCIe IO Accelerator Duo requires a minimum of a full-height, half-
length slot with an x8 physical connection. If your system is using PCI 1.1, all x8
signaling lanes must be connected for full performance. If your system is using PCI 2.0,
only x4 signaling lanes must be connected for full performance.
 300 LFM of airflow at no higher than 50°C
 Sufficient RAM to operate. The amount of RAM that the driver requires to manage the
NAND flash varies according to the block size you select when formatting the device
(filesystem format, not low-level format). The following table shows the amount of RAM
required per 80GB of storage space, using various block sizes:
Average Block Size (bytes) RAM Usage (megabytes)
8192 400
4096** 800
2048 1500
1024 2900
512 5600
* For a PCIe IO Accelerator, using PCIe slots greater than x4 does not provide
additional performance.
