Product Overview 13
Product Overview
The HP StorageWorks Virtual Arrays are Fibre Channel disk arrays featuring
scalability, high performance, and advanced data protection. The VA 7000
Family includes the following models:
■VA 7100 - an entry level array that includes a single controller enclosure
with up to 15 disks.
■VA 7110 - a medium-capacity array that includes a controller enclosure
with up to 15 disks, and supports up to 2 additional external disk
enclosures each capable of housing 15 disks.
■VA 7400 - a high-capacity array that includes a controller enclosure with
up to 15 disks, and supports up to 6 additional external disk enclosures
each capable of housing 15 disks.
■VA 7410 - a higher-performance model of the VA 7400 that increases the
transfer speed between the array and disk enclosures to
2 Gbits/second, increases the amount of cache to 2 Gbytes, and adds
additional host and disk Fibre Channel ports.
Table 1 lists the VA 7000 Family configurations. Figure 1 illustrates the
enclosure configuration for the VA 7400/7410 products.
Both the controller enclosure and the disk enclosure can house up to 15 disk
modules in any combination of 18 GB, 36 GB, or 73 GB disk capacities. The
VA 7410 and VA 7110 also support 146 GB disk modules. The maximum
configuration for a VA 7400/7410 includes 105 disk drives with a total
capacity of 7.67 TB. The controller enclosure includes one or two array
controllers that use advanced storage technology to automatically select the
proper RAID level for storing data.
The array can be connected to one or more hosts, hubs, or switches via fiber
optic cables. Factory-racked products are shipped pre-configured in HP Rack
