Vls9000-Series Configurations; Tb System With Expansion Disk Array Enclosures - HP StorageWorks 12000 - Virtual Library System EVA Gateway Manual

• With VLS12000 Gateway, VLS6600, and VLS9000, data compression is provided by a hardware
compression card that does not impede performance.
• The VLS12000 Gateway and the VLS9000 provide high reliability, dual paths between the node
and the storage pools, and redundant power supplies and cooling.
• The VLS9000–series is scalable enough to be a single or multi-node device
node configuration, it retains the manageability of a single device. VLS9000 also offers the ability
to easily expand the device's performance and capacity after the initial purchase.
VLS9000–series Configurations
At the smaller end, the VLS9000 7.5 TB and 10 TB systems consist of one node, one Ethernet switch,
one base disk array enclosure, and up to three expansion disk array enclosures. See
typical, larger VLS9000-series system consists of at least one VLS9000 node, at least one VLS9000
array (one base disk array enclosure and three expansion disk array enclosures), and one VLS9000
connectivity kit (two Ethernet switches for internal inter-node connections and two Fibre Channel
switches for disk storage connections).
If you have a 20–port connectivity kit, you can install a total of ten devices, consisting of a combination
of arrays and nodes. If you have a 32–port connectivity kit, you can install a total of 16 devices. By
interconnecting two 32–port connectivity kits with an interswitch link kit, you can further expand the
scalability of VLS9000–series.
kits. This system fills four racks and includes eight nodes, 16 arrays, four Fibre Channel switches, and
four Ethernet switches.
