Sun Fire servers are made by Sun Microsystems. These servers come in entry-level (like the Sun Fire v240), mid-range, and high-end capabilities. If you want to do business on the Internet, you can invest in a SunFire X2100. This entry-level server supports multiple operating systems and has reduced maintenance costs.

The X2100 is a single-processor server which was designed to be cost-effective for the small business user. With this server, you can offer Web services and hosting applications. This server can perform over 16,000 business operations per second, and is easy to scale. This server operates with the AMD Opteron processor. The Proliant 3000 is a larger server, able to handle a number of demanding business functions.

The Sun Fire V20z server is an entry-level server that simultaneously runs 32-bit and 64-bit applications. This server works with multiple operating systems and has up to 16 GB of memory. Grid computing and horizontally-scaled databases are other strong features of this server. The V20z is ideal for web serving and technical computing.

If you need larger servers that can handle heavier demands, the Sun Fire V490 can work with up to four CPUs, while the Sun Fire E6900 can handle up to 24. The maximum memory for the Sun Fire V490 is up to 32 GB, for the Sun Fire E2900 it's up to 96 GB, and for the E6900 it's up to 192 GB. The V480 is in the same family, and well worth a look, as is the V880. The maximum storage for the E6900 is an capacious 77 TB. The Sun Fire E20K is a massive server that can incorporate up to 72 processors working on the Solaris operating system.
