Storage servers
For the storage server option, the Cluster 1350 system communicates over a
Fibre-Channel connection and uses any of the following RAID-capable controllers:
v
FAStT600 storage controller (3 U). Each FAStT600 storage controller supports up
to 14 internal disk drive modules, supporting over 2 TB of storage capacity when
using 146 GB drives. Additional storage can be added to the FAStT600 with up
to seven FAStT EXP700 storage expansion units using optional EXP700
attachment features.
v FAStT700 storage controller (3 U). Each FAStT700 storage controller supports up
to 224 18 GB 15,000 RPM drives or 224 36 GB or 73 GB 10,000 RPM drives
contained in external expansion cabinets.
v
FAStT900 Storage Controller (4 U). Each FAStT900 storage controller supports
up to 16 EXP700 external expansion cabinets. All controllers interface with the
cluster so that the storage nodes communicate with large RAID-protected arrays
of storage.
Storage expansion units
The cluster supports the following disk storage expansion units:
v
EXP400: supports up to 14 Ultra320 SCSI hard disk drives.
v EXP700: supports up to 224 Fibre-Channel hard disk drives.
SCSI/RAID storage controller adapters
The Cluster 1350 supports the following SCSI/RAID storage controller adapters:
v
A ServeRAID
™
-6I Ultra320 SCSI controller supports up to 16 arrays with support
for a maximum of 160 hard disk drives.
v A ServeRAID-6M Ultra320 SCSI controller supports eight arrays with support for
a maximum of 30 hard disk drives.
Console
The console provides the monitor, keyboard, and mouse for the management node.
The monitor is a 1 U flat-panel display that folds down and retracts into the rack.
KVM switch
The keyboard/video/mouse (KVM) switch allows the console to connect to all the
nodes in the cluster from one terminal location. Storage and management nodes
are connected directly to the KVM switch. For cluster nodes in the same rack, you
can configure multiple nodes on one KVM switch port.
The Cluster 1350 can use the IBM NetBAY
™
2x8 console switch or the NetBAY
Remote Console Manager (RCM). The RCM is the only supported KVM switch
option that can be used with the
Eserver
325 server.
10/100 Mb Ethernet switch
The 10/100 Mb Ethernet switch provides 10/100 Mb Ethernet connections for the
cluster. The Cluster 1350 uses the Cisco Ethernet switch models 3550 XL (24-port)
and 3550 XL (48-port). You can partition the switch to set up multiple independent
LANs within the same switch.
Each model also provides two 1 Gb Ethernet ports for communication with the
management node.
