Original release.
|
HP Enterprise Virtual Array (EVA) performance and related
host I/O latencies can be affected by complex random and sequential
workloads that the HP EVA is processing. SAN performance depends on
many factors including workload patterns, application tuning, server
and SAN hardware, host bus adapter (HBA) driver settings, switch settings,
and storage array capabilities and configuration.
With
Windows 2003 and the initial release of Windows 2008 and the related
Emulex and QLogic HBAs and drivers, sequential workloads may result
in the maximum default data transfer or block size received by the
EVA of 512 KB. Given a sufficient workload demand on the EVA, including
one or more hosts and applications, and default HBA queue depths of
32, the host I/O latencies might be higher than desired. One tuning
option available with the HBA drivers is to tune the HBA queue depth
to lower values. Workload latencies, throughput and IOPs may see improvements
with reduced queue depth values as the demand on the EVA would be
less, resulting in better latency response times. Another option,
now available with the latest release of the Emulex and Qlogic HBA
drivers, allows the ability to tune the data transfer size to values
smaller than the default of 512 KB. The latest release of the Brocade
HBA driver allows the ability to tune the data transfer size to values
smaller than the default of 2048 KB.
SCOPE
Products affected
by this customer advisory are as follows:
HP 4400 Enterprise
Virtual Array
HP 6400/8400 Enterprise Virtual Array
HP 4000/6000/8000 Enterprise Virtual Array
HP
4100/6100/8100 Enterprise Virtual Array
HP 3000/5000
Enterprise Virtual Array
HP P6000 Enterprise Virtual
Array Systems
RESOLUTION
The Emulex and Qlogic drivers have been enhanced
to allow the ability to optionally tune the data transfer size to
less than 512 kbytes. The Brocade driver has been enhanced to allow
the ability to optionally tune the data transfer size to less than
2048 kbytes. The Smart Components for these components can be located
on the HP website at
www.hp.com
.
Emulex Driver
Emulex driver version 2.42.002 or later, along with OneCommand Manager
version 5.1.53.2 or later, have been enhanced to allow the ability
to optionally tune the data transfer size to less than 512 KB. OneCommand
is used to modify the maximum data transfer size. Emulex has added
a new parameter, LimTransferSize , which operates in conjunction with
the ExtTransferSize parameter to increase the selectable range of
the maximum transfer sizes. Both the LimTransferSize and ExtTransferSize
parameters are available at the server level and also at the port
level, which allows the data transfer size to be selected on a per
HBA port or Mezzanine port basis. The new range of data transfer size
values are as follows: 64 KB, 128 KB, 256 KB, 512 KB, 1 MB, and 2
MB. The data transfer size functionality is available for both the
fibre channel (FC) and fibre channel over Ethernet (FCoE) protocols
as follows.
-
LimTransferSize
valid values:
-
0 = default:
This enables the value selected via the ExtTransferSize parameter
to become the maximum transfer size allowed by the driver.
-
1 = 64kbytes — maximum transfer size
allowed by the driver
-
2 = 128kbytes
— maximum transfer size allowed by the driver
-
3 = 256kbytes — maximum transfer size allowed by the driver
-
ExtTransferSize valid values:
-
0 = default, 512kbytes — maximum transfer size allowed by the
driver
-
1 = 1 Mbyte — maximum transfer
size allowed by the driver
-
2 =
2 Mbytes — maximum transfer size allowed by the driver
Examples
to tune the server or port level transfer size:
-
128 kbytes, set the LimTransferSize = 2 and ExtTransferSize
= 0 (default)
-
512 kbytes, set
the LimTransferSize = 0 (default) and ExtTransferSize = 0 (default)
-
1 Mbytes, set the LimTransferSize =
0 (default) and ExtTransferSize = 1
QLogic Driver
QLogic driver, version 9.1.8.28 or later, has been enhanced
to allow the ability to optionally tune the data transfer size to
less than 512 KB.
The command line utility, \Program
Files\hp\qlogic\qlfc.exe is used to modify the maximum data transfer
size used by the HBA or mezzanine card. A help.txt file is located
in the directory with the utility which provides additional information.
The data transfer size functionality is available for both the FC
and FCoE protocols. The new range of data transfer size values are
64 KB, 128 KB, 256 KB, and 512 KB.
-
Execute the
qlfc.exe
utility without any arguments to display the following
help content:
-
qlfc [-list] [-trace] [-tsize [/fc | /fcoe [/set [64
| 128 | 256 | default] ] ]]
(QLogic
FC Utility)
-
-list
(List all HBA
instances)
-
-trace
(Capture driver trace of
all HBA instances)
-
-tsize
( Show current
transfer size setting for both fc & fcoe)
-
-tsize /fc
(Show current transfer size setting for fc)
-
-tsize
/fcoe & nbsp
(Show current transfer
size setting for fcoe)
-
-tsize /fc /set value
(Set transfer size parameter for fc)
-
-tsize /fcoe /set value
(Set transfer size parameter for fcoe)
Examples:
Brocade Driver
Brocade driver, version 2.3.0.2 or later, has been enhanced
to allow the ability to optionally tune the data transfer size to
values other than the default of 2048 KB.
The command
line utility,
\Program Files\HP\Brocade\util\bcu.exe
is used to modify the maximum data transfer size
bfa_max_xfer_len
used
by the HBA or mezzanine card. The new range of data transfer size
values are 64, 128, 256, 512, 1024, 2048, 4096, 8192, 16384. All values
represent the transfer size in kilobytes (KB).
-
Execute the
bcu.exe
utility to set the value of
bfa_max_xfer_len
(default 2048):
