How does your business achieve server room energy efficiency – whilst working with computer systems that must be up and running 24/7? Balancing the need for an always on world against reducing carbon emissions, saving energy and reducing costs is a constant challenge. Organisations running critical applications simply cannot afford downtime / financial losses / loss of reputation or safety risks. So how do you achieve this?
Server virtualisation has been around for many years now and is an obvious way to consolidate the number of physical servers in use by carving up the available resources and applying applications into individual virtual machines that share the physical cores, RAM and disk space. So, rather than running say 6 individual servers with their associated power and consumables it makes sense to virtualise and run those applications on individual virtual machines instead. We still have 6 x separate software systems, now running on a single server (albeit a beefier version than the 6 individual ones) but overall using less power, less maintenance and less emissions.
But what happens if that server fails? Previously a single server failing wasn’t so bad – only one system was affected and needed attention but now ALL systems are affected. A term we have used several times is if you are putting all your eggs in one basket, then you need a very strong basket.
By introducing a second server and applying fault tolerant technology, your virtual server environment is now real time mirrored between the two physical servers in terms of disk, CPU and memory transactions. Any server faults are detected and tolerated, with the resources of the two physical servers being used as a single resource. The effect? less server hardware, INCREASED system availability and server room energy efficiency.
24/7 Uptime provide the highest possible levels of fault tolerance and server virtualisation as authorised partners of Stratus Technologies. Stratus provide 3 different levels of resilience with virtualisation:
everRun (software applied to standard off the shelf servers)
ztC Edge (dedicated industrial servers running Stratus fault tolerant software)
solid state ftServer – the ultimate in computing power and system resilience with more than 99.99999% levels of availability.
No shared storage, no failover outages, no downtime, no data loss = server room energy efficiency.
