Expansion Arrays further preparation (other than preparing rack space) is necessary; the Snap Disk 30SA comes with the necessary cables. Otherwise, you will need to purchase and install the Snap Appliance fibre channel card, available from an authorized Snap Appliance reseller. The Snap Disk 32SA The Snap Disk 32SA expansion array works with a Snap Server 15000 or 18000. You can daisy chain up to seven Snap Disk 32SAs via optical cables. Each expansion array holds up to 16 disk drives. A Snap Disk 32SA expansion array is connected to the network and managed though the Snap Server to which it is connected. The expansion array has no physical connection to the network or independent IP address. After the Snap Disk 32SA is installed and powered on (see the quick start guide for details), the array's disk drives appear as unassigned drives, allowing the administrator to configure RAIDs as necessary. Preparing the Snap Server 15000 The Snap Server 15000s ships with an expansion array and no additional hardware or preparation is required for connectivity. Preparing the Snap Server 18000 Some Snap Server 18000s ship with a fibre channel card installed for connectivity to Snap Disk 32SA expansion arrays. If your server already has the fibre channel card, no further preparation (other than preparing rack space) is necessary; the Snap Disk 32SA comes with the necessary cables. Otherwise, you will need to purchase and install the Snap Appliance fibre channel card, available from an authorized Snap Appliance reseller. Managing Expansion Array Storage The four disk drives of a Snap Disk 10 are preconfigured as a RAID 5 with a single volume and a single share to the volume. The 16 disk drives of the Snap Disk 30SA and Snap Disk 32SA are not preconfigured but are shipped as unassigned disk drives, allowing administrators to configure the array as appropriate. Once connected to and integrated into the host Snap Server, the Snap Disk 10's storage configuration appears as an additional RAID, volume, and share in the host server's Administration Tool. For example, if the host server retains the default storage configuration and names (md0, VOL0, SHARE1), an array will appear in the host server's Administration Tool as md1, VOL1, and SHARE2. The disk drives of any attached Snap Disk 30SAs and Snap Disk 32SAs appear in the Administration Tool as unassigned drives. Chapter 4 Storage Configuration & Expansion 37
