Expansion Arrays SANbloc S50s can be connected to a Snap Server 520, 550, 650, or 18000. Up to three SANbloc S50s can be connected to a Snap Server 4500. Note Specific configurations are recommended when SAS and SATA drives are combined in the same expansion array. Be sure to review the S50 Quick Start Guide before configuring a mixed-drive array. A SANbloc S50 expansion array is accessed and managed through the Snap Server to which it is connected. The expansion array has no physical connection to the network. After the SANbloc S50 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 The Snap Server 550 and 650 ship with a SAS HBA installed for connectivity to SANbloc S50 expansion arrays. If your server already has a SAS HBA, no further preparation (other than preparing rack space) is necessary. To connect a SANbloc S50 to a Snap Server 520, 4500, or 18000, you will need to purchase and install the SAS HBA, available from an authorized Snap Server reseller. Note If you plan to add a SAS HBA to a Snap Server 4500, make sure there is an available PCI slot. Managing Expansion Array Storage The 12 disk drives of the SANbloc S50 are not preconfigured, but are shipped as unassigned disk drives, allowing administrators to configure the array as appropriate.
