So electricity may be a problem only if there is a power supply failure (server has only one power source). | |
| Mar 14, 2017 at 9:41 | comment | added | Kinnectus | if the server is "in-house" (leased and is physically accessible by you/your team) then buy a UPS for up to a few hundred pounds. If your dedicated server is leased through, say, a data centre, then enquire with them as to why they haven't got UPS for their customers and/or if they provide them at additional cost. A UPS gives your server enough time to finish tasks and perform a normal shutdown rather than a sudden power loss and the small RAID battery only being able to flush its cache to disk but leave the OS in a potentially worse situation. | |
| Mar 14, 2017 at 9:16 | comment | added | Hennes | it is always a balance between money and features, but for this config I would worry more about an UPS (and thus no need for a battery backed cache on a RAID card) than on the RAID cards setup. Now if performance is an issue things might be different. | |
