Dell PowerEdge R820 review

Dell’s PowerEdge R820 is the first Xeon E5-4600 production server to market. We take a look at this compact four-socket server, which can be used to manage heavy duty databases, virtualisation, HPC and VDI hosting.

Price
£12,563

Dell consistently beats its rivals to market with new server technology, so it's no surprise the PowerEdge R820 sports Intel's latest Xeon E5-4600 processors.

When Intel launched its Xeon E5-2600 CPUs in March, their vital statistics were known well in advance, but not so with the E5-4600 family. This group consists of eight models ranging in speeds from 2GHz up to 2.9GHz with 4, 6 or 8 cores and 10MB, 12MB, 15MB, 16MB or 20MB L3 caches.

The R820 was equipped with a quartet of 6-core 2.2GHz E5-4607 Xeons which had a 12MB L3 cache, a 6.4GT/sec QPI and a low 95W TDP. These models support memory speeds up to 1066MHz and Intel's HyperThreading, but not Turbo Boost.

The E5-4600 family is designed for scalable dual and glue-less quad-socket platforms. As with the E5-2600s, they have two QPI links per socket supporting speeds up to 8GT/sec and in a 4P system will connect with adjacent sockets in a ring architecture.

Memory and storage aplenty

A key feature is memory capacity. The 4P system supports 48 DIMM sockets and can scale up to 1.5TB using 32GB LR-DIMMs. You may think this puts it in direct competition with the Xeon E7 but Intel has positioned the E5-4600 as a better choice where a balance of cost, performance, power consumption and memory capacity is required.

The R820 uses a similar chassis to the PowerEdge R720 and so has a good range of storage options. It supports 16 SFF hard disks and there's also an option with eight standard SSF bays and four hot-plug PCI-e Express Flash SSDs.

RAID options start with the basic PERC H310 entry-level adapter but review price includes the top dog PERC H710P PCI-e card which supports RAID-6 and has a 1GB NVRAM cache so doesn't need a battery backup. It uses an LSI chip and you can enable its optional CacheCade feature which optimises read activity from an SSD based cache.
