Dell PowerEdge R910 review

RAID options are present and correct as the Dell H700 controller can handle all 16 bays if required and includes support for RAID-6 arrays. It also comes as standard with 512MB of cache memory plus a battery backup unit.

Dell was first to add a bootable SD memory card for embedded hypervisors and with both the R810 and R910 it's gone one step beyond as you now get two of them on the same board. Dell advised us that customers wanted redundancy so you can now keep an onboard copy of the boot media in case it fails. However, Dell still only supports VMware's ESXi and not Hyper-V.

There's a lot going on inside the R910 but a peek under the lid shows an excellent design with every key component easily accessible. Dell has made it completely tool-less so you can leave your screwdrivers at home when it comes to maintenance or upgrade maneuvers.

At the front you have eight cold-swap memory modules each with eight DIMM slots allowing the R910 to support the full 1TB. With 64 addressable memory slots there's no need to support Dell's FlexMem Bridge. This feature is only available in the R810 rack server and the M910 server blade which have 32 DIMM slots.

The processors are laid out across the centre of the chassis and topped off with large passive heatsinks whilst cooling is handled by a bank of six 12cms diameter fans behind them. Each fan is hot-swappable but the entire assembly can also be easily removed by releasing a clamp on each side.

The review system came with all four 1100W hot-plug supplies for maximum redundancy but you can opt for 750W models if your hardware expansion plans are modest. And on that note, there's plenty of room for more inside with a total of seven PCI-e slots which can be extended to ten slots with an optional riser card. However, we did find that the distance between the fans and the backplates may not be enough for some full length cards.
