Eudora is the Analysis Node of the Hyades cluster. It is a Dell PowerEdge R820 server, equipped with four (4x) 8-core Intel Sandy Bridge Xeon E5-4640 processors at 2.40GHz, and 512 GB memory.
Dell OpenManage Server Administrator (OMSA) reports that the RAID controller is a PERC H310 (see also Dell OpenManage):
# /opt/dell/srvadmin/bin/omreport storage controller Controller PERC H310 Adapter(Slot 7)but is actually a rebranded LSI MegaRAID SAS 2008:
# lspci | grep RAID 02:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS 2008 [Falcon] (rev 03)
There are two (2x) 600GB Intel 320 Series SSDs on the RAID controller.
For maximum performance, a RAID-0 virtual disk (volume) is created from the 2 SSDs:
# /opt/dell/srvadmin/bin/omreport storage vdisk controller=0 Virtual Disk 0 on Controller PERC H310 Adapter (Slot 7) Controller PERC H310 Adapter (Slot 7) ID : 0 Status : Ok Name : VD0 State : Ready Hot Spare Policy violated : Not Applicable Encrypted : Not Applicable Layout : RAID-0 Size : 1,116.75 GB (1199101181952 bytes) T10 Protection Information Status : No Associated Fluid Cache State : Not Applicable Device Name : /dev/sda Bus Protocol : SATA Media : SSD Read Policy : No Read Ahead Write Policy : Write Through Cache Policy : Not Applicable Stripe Element Size : 64 KB Disk Cache Policy : Enabled
There are 4 on-board Broadcom Ethernet interfaces:
# lspci | grep Ethernet 01:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM57800 1/10 Gigabit Ethernet (rev 10) 01:00.1 Ethernet controller: Broadcom Corporation NetXtreme II BCM57800 1/10 Gigabit Ethernet (rev 10) 01:00.2 Ethernet controller: Broadcom Corporation NetXtreme II BCM57800 1/10 Gigabit Ethernet (rev 10) 01:00.3 Ethernet controller: Broadcom Corporation NetXtreme II BCM57800 1/10 Gigabit Ethernet (rev 10)The first 2 (em1 & em2) are 10GbE interfaces; and remaining 2 (em3 & em4) are GbE interfaces.
There is a Mellanox ConnectX-2 VPI single-port adapter:
# lspci | grep Mellanox 41:00.0 InfiniBand: Mellanox Technologies MT26428 [ConnectX VPI PCIe 2.0 5GT/s - IB QDR / 10GigE] (rev b0)which can be configured either as QDR InfiniBand or 10 GbE. Since the interface is InfiniBand by default, there is no need to modify /etc/rdma/mlx4.conf, which can be left blank (see also Pleiades).
The IP addresses of the network interfaces are (see also Hyades Networks):
