Server configuration

This section describes how to configure the PC servers, which must run a 64-bit OS. The Avaya Data
Solutions Test Lab setup uses five PC servers running CentOS 5.5 (x64-bit version).
You also have to install Coraid HBA cards in each PC server. The Coraid HBA provides functionality
similar to a NIC card. The Coraid HBA card requires a PCI Express slot. After installing the Coraid HBA
cards, you also have to install the Coraid HBA driver in each PC server.
Before you can use the SAN storage through your Coraid HBA, you have to configure one or more
Logical Unit Adapters (LUN) on the Coraid EtherDrive SRX-Series storage appliance. Figure 2 shows a
sample LUN configuration where with just three commands (make, spare and online), you can:
1) create RAID groups
2) assign hot spares
3) bring LUNs online
Use the following steps to configure the PC servers:
1) Use the make command to configure five different RAIDS of various sizes on the SRX-Series
appliances. Coraid EtherDrive SRX-Series appliances automatically create one LUN per RAID
group.
2) Use the spare command to assign hot spares.
3) Use the online command to bring the RAIDs online.
4) Use the ethdrv-stat command to confirm that each PC can communicate with the drives and the
drives are mountable.
5) Use the mkfs command to create and format a file system on each RAID. The AoE protocol
makes the RAID look like a local storage device:
mkfs -t ext3 /dev/<device>
