Server Racks – Do We Need Them?
Category : IT Infrastructure Setup 24 Sep 2009 09:36 AM
If you have any doubt whatsoever as to whether or not we need servers racks, simply visit two computer installations one with server racks and one without - and you'll instantly agree that yes we do need server racks. Utilizing server racks is one of the ways that can help you to achieve a structured cabling system within your network solutions to data communications.
Why you need a server rack.
Visiting a computer installation without a server rack you'll see cables trailing over the floor, hubs, switches and routers balanced on desks or shelves and the server itself in what can only be described as an unprotected location; where it is liable to get knocked down or have things spilt on it - causing interruptions to its ability to work efficiently. In contrast network servers installed into a server rack will be rigidly fixed in a frame-work above ground level, with any hubs, switches or local routers all also secured in the rack. Cabling will enter the frame-work housing the racked components at one point and certainly above ground level. In other words utilizing server racks fixes all of the network components in one place allowing you to arrange things logically - making it easier to locate any cabling faults and thereby reducing any down-time.
Server racks and physical server security.
The physical aspect of the IT security of your servers can also be improved by having them in an appropriate rack system. Rack servers can be screwed and bolted into the rack making them far less susceptible to theft, compared to servers just left standing on floors. Racked servers will also have clearance between each unit, allowing air to circulate around them properly, keeping them cool and less likely to fail due to over-heating.
Choosing a server rack.
The importance of choosing the right server rack for your computer installation cannot be overstated and seeking expert advice from a Hong Kong IT services provider like Dual Layer Solutions cannot also be over-stated. I have literally seen a network manager resorting to hitting a server rack with a sledge hammer - whilst the servers are resting in the rack - in order to make the rack fit the servers! This is, of course, not to be recommended. Furthermore, ordering a server rack that exactly fits only your existing servers and equipment could turn out to be a false or short term savings. OK, so by buying a server rack exactly to meet what you have now might save a few dollars – it is likely that a company will increase their IT operations in the future, thus needing more space. A company offering services like Dual Layer Systems Solutions will advise you to buy a server rack with excess capacity, not just to increase their sales - but so that in a few months or years time you're not having to buy a completely new server rack, as your IT demands increase. They can also advise you on the best location for it and can provide an IT outsourcing service to fit and install it, without needing to use a sledgehammer!
New equipment for your server rack.
Chances are that if you're considering buying a new server rack you're probably looking to buy new server equipment too, if not, this may be an ideal time. Servers, hubs, switches and routers are available from many manufacturers from the top international names like HP, IBM and Sun etc, through to less well known but equally reliable Hong Kong manufacturers. The one piece of advice that is usually best to follow through with states than when possible and according to your budget, buy all of the components from the same manufacturer. This will make maintenance, upgrades and updates far easier as a manufacturer will always want to minimize any legacy issues for their own equipment; ahead of worrying about other manufacturers. Not to mention that any trouble-shooting will only require you to deal with one company, rather than trying to explain a particular situation to several.
