Expansion Arrays The Snap Disk 10 The Snap Disk 10 expansion array allows you to expand the capacity of a Snap Server 4500 (only) without increasing administrative tasks. You can attach up to two Snap Disk 10s via a Serial ATA cable to a Snap Server 4500. Each expansion array holds four disk drives. A Snap Disk 10 expansion array is powered on, connected to the network, and managed though the Snap Server 4500 to which it is connected. The expansion array has no power button, physical connection to the network, or independent IP address. After the array is installed and the host server is powered on, the expansion array automatically powers on as well. The Snap Server 4500 adopts the four new disk drives of the array into its storage configuration. Preparing the Snap Server 4500 The following modifications must be made to the host Snap Server 4500 before the installation of a Snap Disk 10 expansion array. • Serial ATA Card - You must purchase (from an authorized Snap Appliance reseller) and install a SATA card on the Snap Server 4500 before connecting a Snap Disk 10. • OS Requirements - The Snap Server 4500 must have GuardianOS v2.6 or higher installed to interoperate with the Snap Disk 10. The Snap Disk 30SA The Snap Disk 30SA expansion array works only with a Snap Server 15000 head unit or Snap Server 18000. You can daisy chain up to seven Snap Disk 30SAs via optical and copper fibre channel cables. Each expansion array holds 16 disk drives. A Snap Disk 30SA 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 30SA 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 30 expansion arrays. If your server already has the fibre channel card, no 36 Snap Server Administrator Guide

Snap Server Administrator Guide
The Snap Disk 10
The Snap Disk 10 expansion array allows you to expand the capacity of a Snap
Server 4500 (only) without increasing administrative tasks. You can attach up to
two Snap Disk 10s via a Serial ATA cable to a Snap Server 4500. Each expansion
array holds four disk drives.
A Snap Disk 10 expansion array is powered on, connected to the network, and
managed though the Snap Server 4500 to which it is connected. The expansion array
has no power button, physical connection to the network, or independent IP
address. After the array is installed and the host server is powered on, the
expansion array automatically powers on as well. The Snap Server 4500 adopts the
four new disk drives of the array into its storage configuration.
Preparing the Snap Server 4500
The following modifications must be made to the host Snap Server 4500 before the
installation of a Snap Disk 10 expansion array.
•
Serial ATA Card —
You must purchase (from an authorized Snap Appliance
reseller) and install a SATA card on the Snap Server 4500 before connecting a
Snap Disk 10.
•
OS Requirements —
The Snap Server 4500 must have GuardianOS v2.6 or higher
installed to interoperate with the Snap Disk 10.
The Snap Disk 30SA
The Snap Disk 30SA expansion array works only with a Snap Server 15000 head
unit or Snap Server 18000. You can daisy chain up to seven Snap Disk 30SAs via
optical and copper fibre channel cables. Each expansion array holds 16 disk drives.
A Snap Disk 30SA expansion array is connected to the network and managed

physical connection to the network or independent IP address. After the Snap Disk
30SA 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 30 expansion arrays. If your server already has the fibre channel card, no
