Storage areas networks--the most powerful technology available for block-level storage--have been part of the enterprise landscape for years. But new products aimed at small and midsize businesses have come off the drawing boards at such companies as Dell and HP, putting the technology within reach of companies with smaller pocketbooks. But before recommending a SAN solution for a client, keep in mind the company's budget, applications, workload, and projected growth. Here's a roundup of seven solutions worth investigating.

This array supports up to 16 SATA or SAS drives per chassis and is available with single or dual controllers. It scales to 192 TB per PS Series group and supports up to 512 servers. The PS5000E also comes with a soup-to-nuts collection of features such as snapshots, replication, and thin provisioning that are often extra-cost options on competing products.
Dell PowerVault MD3000i iSCSI SAN
The MD 3000i is an entry-level iSCSI SAN that supports up to 16 servers and is available with single or dual controllers. Up to 15 SATA or SAS drives may be used per enclosure, up to a maximum of 15 TB, and up to two expansion enclosures may be added for a total capacity of 45 TB. Snapshots are an option.
