The following examples show how customers like you have used storage solutions based on the HP StorageWorks Modular Smart Array family to solve their specific business challenges.
Two-node cluster with MSA2000sa
»
The HP MSA2000sa enables external storage to be configured within a four-node cluster without having to invest in a fibre-channel network. In this scenario, two servers are connected redundantly via SAS cables to the storage array, and act as fallback or recovery servers to each other. The cross-over connection is used as a heartbeat listening connection for the two servers.
Consolidation into an IP SAN
For small but growing environments, networked storage through an IP SAN offers a great balance between efficiency and affordability. This can be achieved either array based using the MSA2000i, or server-based using the HP ProLiant Storage Server with iSCSI Feature Pack. While it is possible to share the same network, HP recommends separating the storage network from the public LAN for performance reasons. When using an MSA2000i, you may design a redundant infrastructure using two switches.

Starter fibre channel SAN with the MSA2000fc
When consolidating storage from multiple servers (clustered or non-clustered), a SAN solution based on the MSA2000fc offers the best efficiency, flexibility and scalability. Here we see dual configuration that achieves full redundancy. If you want to lower cost, a single configuration is available, although you will have reduced availability in the event of a failure. scenario also shows servers which are usually not connected to a SAN.

Fully integrated high-availability SAN
In this scenario, the MSA2000sa provides the option of low-cost near-online storage based on SAS (Serial Attached SCSI) disks. A second SAN at a remote site using SAS is also shown. Data can be copied from SAN 1 to SAN 2 using IP replication - enabling data to remain available, even if a disaster occurs at the primary site.
