What’s in a server?

A ‘proper’ server
Another big drawback to a Nas appliance is that most can only be used to provide shared network storage.

If you want to be able to run other applications, such as your own web, email or database server, for example, then a general-purpose server running Windows or Linux will be needed, and that can involve lots of decisions to make sure it’s right for you.

The golden rule is to ‘buy the best you can afford’. That means fixing a budget to include both hardware and software and choosing one of the big brand names, such as Dell, Fujitsu-Siemens, HP, IBM, or NEC.

That way you make sure you have the best technology, together with good backup and support services. It also means opting for a server specification that will suit your current requirements and allow for further expansion and changes.

Unfortunately, sizing a server is something of a fine art and you may want to seek expert help before parting with any cash.

However, we have listed below the key features to look for, together with a number of general recommendations that are applicable to small-business buyers.

Processor
Dual-core processors are worth buying, even for basic file-server duties, although on a small network very little processing work is involved. If you w ant to run server-based email, web or database servers, look for multiprocessor servers and choose SMP for virtualisation.

Memory
Choose Error Checking and Correction (ECC) memory for reliability. At least 1GB will be required, even for basic file and print sharing, with more needed to handle additional applications – check what the software vendors recommend and then double their suggestions.

Storage
Size the disk storage carefully. You’ll need enough space for the operating system and any applications you want to run, plus all your shared data.

If possible, go for storage that can be easily expanded should your requirements increase. Hot-swapping of disks isn’t something most small businesses require.

Consider multiple disks, or mirrored and Raid-protected storage arrays for additional reliability.
