Windows Server 2008 R2 and Windows Server 2008 R2 with Service Pack 1 on HP Integrity Servers Release Notes v7.1

This error occurs if the IPMI driver was being updated when the Event
Synchronization Process tried to access IPMI SEL information.
Servers All Integrity
Workaround There is no workaround. After the IPMI driver update is completed, the Event
Synchronization Process can read the IPMI SEL entries successfully.
New events in the System Event Log (SEL)
Issue When viewing the SEL events from the MP SL viewer, you might see some new
events of type DC or DD.
Servers All Integrity
Workaround These are informational events. When the system is booted up, a type DC event
entry is generated in the SEL. When the system is gracefully shut down, one or
more type DD event entries are generated in the SEL.
Unknown IPMI Type-E1 event
Issue The iLO SL (Show Event Logs) menu might report an unknown IPMI Type-E1 event
after an OS boot completed event or after an OS graceful shutdown
occurred event.
Servers HP Integrity BL8x0 i2 Server Blade
Workaround You can ignore these unknown IPMI Type-E1 events as they are duplicates of the
OS boot completed and OS graceful shutdown occurred events.
Network Interface Cards (NICs)
Possible performance issues with 10 Gb NICs in systems with greater than 32 physical CPUs
Issue On systems with greater than 32 physical CPUs and AD385A-HP PCI-X 266MHz
10 Gb Ethernet SR multi-OS cards, under heavy networking traffic an issue with
the NDIS driver can cause system sluggishness and performance issues.
Servers Superdome SX2000
Workaround HP recommends placing the 10 Gb Ethernet cards in the I/O chassis attached
to the root cell. Additionally, if the task manager reports high utilization on CPU0,
HP recommends that you change the RssBaseCpu registry value for the 10 Gb
adapter from CPU0 to a non-zero CPU. See the Receive-Side Scaling
Enhancements in Windows Server 2008 in the Microsoft Knowledge Base for
instructions.
A driver with a workaround will be available soon on http://www.hp.com.
AD385A NIC card can affect server performance under a load
Issue When handling IPv6 traffic, a server with the Neterion AD385A NIC card installed
can exhibit sluggish performance. In some cases, a DPC Watchdog timeout event
occurs.
Servers Superdome SX2000, rx8640, rx7640, rx6600, rx3600, rx2660
Workaround Set the RssBaseCpu registry value in HLKM\System\CurrentControlSet\
Services\NDIS\Parameters to 8 (the default is 4). For more information,
see the Receive-Side Scaling Enhancements in Windows Server 2008 white paper

Server with A9899A or A9900A NIC cards does not reboot after a crash
Problem In the unlikely event of system crash, an Integrity server with the A9899A or
A9900A NIC card installed might fail to automatically restart.
