Expansion Arrays

Chapter 4 Storage Configuration & Expansion 37

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.
