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; each couple of iSCSI ports coming from a single storage processor is connected to an half part of the cluster (28 nodes), featuring a dedicated access to the storage for each part of the cluster.
Have a look at the Hardware section for more information on cluster composition.
