6. Installation Guidelines

6.1 Emulex* LP1050Ex and Qlogic* QLE2360 Fibre Channel

Adapters Experience Delayed Write Failures during Extended

Stress Testing

Issue: During Intel’s extended stress test runs, fibre channel hard drives attached to the
Emulex* LP1050Ex or Qlogic QLE2360 PCI Express fibre channel adapters
begin experiencing delayed write failures and were eventually marked offline.
These failures have only been seen when running under Microsoft* Windows*
Server 2003. Failures have not been seen when running under Novell*
NetWare* 6.5 or Red Hat* Advanced Server 3.0.
Implication: Fiber channel hard drives may experience delayed write failures or the hard
drives may be marked offline if the Emulex* LP1050Ex or Qlogic QLE2360 PCI
Express fiber channel adapters are utilized in combination with the Intel® Server
Board SE7320SP2, SE7520BD2, SE7520AF2, SE7520JR2, or SE7320VP2 and
the Microsoft* Windows* Server 2003 operating system, if the system is
subjected to extended periods of intensive I/O application stress.
Guideline: The Emulex* LP1050Ex or Qlogic QLE2360 PCI Express fibre channel adapters
should not be utilized with the Intel® Server Board SE7320SP2, SE7520BD2,
SE7520AF2, SE7520JR2, or SE7320VP2 with the Microsoft* Windows* Server
2003 operating system. The Emulex LP1050Ex or Qlogic QLE236x PCI Express
fibre channel adapters may be used with these server boards with Novell*
NetWare* 6.5 or Red Hat* Advanced Server 3.0.
Status: Intel is currently working with Emulex and Qlogic to investigate a fix for this issue.

6.2 Adapter is supported only with Intel Server Board SE7520BD2

with C4 or later stepping Intel® E7525 server chipset (i.e.

SRCU42E)

Issue: This adapter has only been tested with Intel Server Board SE7520BD2 that
utilize C4 or later stepping Intel® E7525 server chipsets (PBA # C44689-701,
C44688-701, C444686-701 or later revisions).
Implication: This adapter has not been tested with and is not recommended for use with Intel
Server Board SE7520BD2 that utilize C2 stepping Intel® E7525 server chipsets
(PBA # C44689-605, C44688-605, C44686-605). Please reference TA 707-03
for further information.

for further information.
Status: The MCH component stepping change implemented on the Intel Server Board
SE7520BD2 in early Q4 2004 added support for broad PCI Express* adapter
