== Storage description ==
The central storage is composed of 20 FC disks of 300Gb 10000RPM and 70 SATA II disks of 750Gb 7200RPM.
It is managed by using a double cotroller with 2+2 FC ports, connected to the SAN switch in a redundancy and fail over configuration.
Each controller also allows to connect 4 iSCSI hosts.

== Host connectivity ==
There are 2 hosts connected to the SAN by using 2 FC adapters for redundancy and failover capabilities and 6 hosts with a single FC connection to the SAN switch.

Four of the eight iSCSI ports on the storage processors are also used to initialize the storage volumes on the cluster nodes (have a look at the [[Hardware]] section for more information on cluster architecture).
