HP StorageWorks 6000-series Virtual Library System User Guide (AH809-96049, September 2010)

Disk array 02
Disk array 13
An optional third and fourth disk array can be added to a VLS6500 by purchasing one or two VLS
capacity bundles. A VLS capacity bundle includes a disk array with twelve SATA disks and a capacity
license for the additional disk array.
Adding a third and fourth disk array expands the VLS6500 storage capacity as shown in
VLS6500-series capacity. Adding a third and fourth disk array also increases the performance. See
the HP StorageWorks 6000 virtual library system Quickspec on the HP web site (http://
h18006.www1.hp.com/products/storageworks/6000vls) for performance data.
NOTE:
You can also re-use an existing MSA20 disk array with twelve blank SATA disks of the same, supported
type (all 250 GB, all 500 GB, or all 750 GB disks) and the latest MSA20 firmware. Purchase a
capacity license for the additional disk array separately.
