Review: Dell PowerEdge VRTX hits the high notes
Dell's four-blade, 32-drive 'cluster in a box' packs high performance, high availability, and high-end management in a tidy package
Basically a small blade-server chassis, Dell's PowerEdge VRTX packs up to four server blades and as many as 32 small-form-factor disk drives into a self-contained, cluster-in-a-box solution. From a cost and convenience perspective, the cluster in a box is compelling for a wide range of use cases. It's an ideal hardware setup for virtualizing a branch office infrastructure or even certain small to medium-size enterprise workloads.
The PowerEdge VRTX has the horsepower to handle workloads like Microsoft Exchange and the storage space for a large Microsoft SharePoint deployment. The secret sauce is in the Series-8 Shared PowerEdge RAID Controller (PERC) that handles the sharing of storage among all of the blades in the chassis. Internally, the VRTX supports a variety of I/O fabric interfaces including 10GbE, though the current switch only supports 1Gb speeds. An integrated gigabit switch with eight external ports on the rear of the chassis can be used for connecting external Ethernet devices.
My review unit came equipped with two Dell M620 blades each containing two Intel Xeon E5-2650 CPUs and 96GB of memory. You could pack up to 768GB into the 24 DIMM slots inside the M620, if needed. The VRTX chassis will function in either an upright tower configuration or in a standard 19-inch, 5U rack mount. It supports the M620 or M520 blade servers, or a mix of both. Storage options include 12 full-sized drives in lieu of the small-form-factor drives.
