Client / HPC Compute Cluster
Clients
64 PowerEdge R410 compute nodes with Red Hat Enterprise Linux
6.2 x86-64.
InfiniBand
Mellanox ConnectX-2 QDR HCA.
Mellanox OFED 1.5.3-3.0.0.
InfiniBand
fabric
All clients connected to a single large port count InfiniBand QDR
switch (Mellanox IS5100).
Both PowerEdge R620 NFS servers also connected to an InfiniBand
FDR switch (Mellanox SX6036), and the switch has three links each
to the QDR switch (IS5100).
Ethernet
Onboard 1GbE Broadcom 5716 network adapter.
bnx2 driver v2.1.6.
Ethernet
fabric
Two sets of 32 compute nodes connected to two Dell PowerConnect
7048 Gigabit Ethernet switches.
Both Dell PowerConnect 7048 switches have four links each to a 10
GbE Dell PowerConnect 8024F switch.
Both PowerEdge R620 NSS-HA servers connected directly to the Dell
PowerConnect 8024F switch.
Flow control was disabled on the Dell PowerConnect 8024F switch
and two Dell PowerConnect 7048 switches.
4.3. HA functionality
The HA functionality of the solution was tested by simulating several component failures. The design of
the tests and the test results are similar to previous versions of the solution since the broad
architecture of the solution has not changed in this release. This section reviews the failures and fault
