HP StorageWorks 4400 Scalable NAS for File Serving cluster configuration guide (AN595-96010, October 2009)

1 Initial cluster configuration
The HP StorageWorks 4400 Scalable NAS system is shipped with the cluster already
configured.
Networks
HP Clustered File System uses a local network for its administrative traffic. This network
has been configured with IP addresses in the 172.31.0.n network using VLAN #2
on the ProCurve 2910 network switch. VLAN #2 includes the first eight ports on the
switch. This private network must not be connected to your network.
VLAN #1 on the ProCurve switch is intended to be uplinked to your network using
port 24 to allow access to iLO2 on the cluster servers. These Ethernet connections
are configured to obtain IP addresses using DHCP. You will need to update their
configurations if you want to configure them statically.
Storage
The first 12 disks in the storage array are included in the EVA Default Disk Group.
This disk group has three mirrored 1GB disks used as membership partitions for the
cluster and six 250GB RAID5 vdisks used for filesystems. The six filesystem disks are
configured into three volumes with two vdisks each using 1MB stripes. Each vdisk in
the volume pair has one vdisk defaulting to use EVA 4400 controller A and the other
vdisk defaulting to use EVA 4400 controller B. Striping each volume across both
controllers balances the I/O load for better throughput.
The remaining disks in the storage array can be used as necessary for other
filesystems. For best performance, all disks with the same size and performance
should be part of the same disk group.
