This is part two of a two-part post with our recommendations for purchasing “fit for purpose” desktops, laptops and servers for business use (with an emphasis on Small and Medium sized businesses).
Servers:
1) Hardware Specification. With a server you are looking for a machine that will be fit for purpose for between 3 and 5 years, depending on the function of the server. Therefore, you should build in a degree of room for growth within the specification, as follows:
- Hard Disk Capacity. Allow enough hard disk space for growth in your file storage needs. Depending on the industry you work in you can probably expect your storage needs to double (or even triple) each year. You should also allow extra storage for additional staff if you anticipate growing your business over the next 3 to 5 years.
- RAID. Redundant Array of Inexpensive Disks (RAID) is where you use a number of hard disks configured in such a way as to provide built-in redundancy against the hardware failure of any one disk. With an entry level server you should always go for RAID 1 (mirroring), where you have two disks, with one being a copy of the other. There are additional RAID “levels” for larger servers.
- Memory (RAM). Purchase enough memory to support your immediate needs and those further down the road. With a server, you can never really have too much memory; buy as much as you can afford.
- Maximum RAM. Modern servers can accommodate massive amounts of memory (up to 2TB), but each physical server model will have its own model-specific limitations. For example, entry level servers will have a maximum of 8GB, while the next level up will most likely have a limit of either 24GB or 32GB. When planning for growth you should think about whether or not you need to purchase a model that will allow you to expand the memory beyond 8GB in the future. Note: Microsoft Small Business Server 2008 requires a minimum of 4GB, but 8GB is recommended.
- Processor (CPU). As with desktops and laptops, most manufacturers will offer you a range of processors within each server model. In many cases the base processor will easily be sufficient for your needs. Some entry level servers may still be offered with the option of a Dual Core processor. If this is the case, then I would recommend stepping up to at least the first Quad Core processor offered. If you have a bit of room in your budget, then going for the best processor that you can afford will future proof your server more.
- Number of Processors. Entry level servers can accommodate one processor. The next level up will support two processors. One processor will be sufficient for most small business server requirements, unless you have a heavily used database server or are using virtualisation.
- Power Supplies. Ideally you should go for a server that has two power supplies. This provides built-in redundancy should one of the power supplies fail (they do occasionally). Many entry level servers do not come with, or offer the option to have, a second power supply.
2) Vendor Choice. Always purchase from tier-1 vendors, such as Dell, HP, and IBM. There was a time when Compaq (now part of HP) were the undisputed leader in the server market, with IBM coming second. These days, for small and medium sized business, there is no real difference (other than price) between Dell, HP and IBM.
3) Payment Options. If you are not cash rich then you should lease your server across 3, 4 or 5 years. Manufacturers like Dell will offer you various leasing packages, as do various asset finance companies. Solutions Shared can also finance your server purchase (plus the software and installation costs) via Microsoft Finance.
4) Warranty. Always take out a minimum of 3 years Next Business Day (NBD) warranty for your server. Depending on the business criticality of your server, you can take out additional warranty levels, such as 4 hour response, 4 hour fix, 24 x 7 coverage, etc. Running a server without the basic 3 NBD warranty is madness.
