In the Lab: Netgear Ethernet Networking Infrastructure
One of the more integral components in any lab is its traditional Ethernet networking infrastructure connecting servers, storage, networking and related components. While high-speed interconnects such as 10/40GbE, Infiniband or Fibre Channel might be the primary production links for storage or other means, gigabit is still needed to make all that gear manageable. For every switch, server or storage array, the management or KVM ports are required for day to day upkeep. This article covers what makes the StorageReview Test Lab tick when it comes to Ethernet fabric.

In the Lab: Studio Photography of Large Equipment
Behind the scenes at StorageReview, we go to great lengths to offer detail-oriented photography you see published in reviews. To make this possible, we have an on-site studio where we can shoot devices as small as micro-SD cards and as large multi-shelf storage arrays. This setup includes three main components; a large light tent, a dSLR camera and a ton of continuous lighting... 1000 watts of CFLs or roughly 65,000 lumens. Those compnents along with some heavy lifting make our images possible.

In the Lab: Smart Cooling
As the StorageReview Test Lab continues to grow in terms of testing capacity and testing load at any given time, the cooling requirements and associated costs balloon as well. With 2,000-6,000 watts of compute activity throughout the week, or about 7,000 to 20,000 BTU of heating capacity, the costs just to cool the space can get quite hefty. The approach we've taken to address HVAC in our lab and building not only helps save us money, but literally heats our building during the heating months. While our needs may not be representative, most small data centers that start as telco rooms then grow into a rack or more of compute and storage, can have similar problems.

In the Lab: Mellanox SX1024 Switch Configuration
In today's look into the StorageReview Lab, we are working on the initial configuration of a new Mellanox 10/40Gb Ethernet switch, the SX1024. Offering 48 10Gb SFP+ ports and 12 40/56Gb QSFP+ ports, it adds an immense number of ports to our top-of-rack connectivity for high-speed storage arrays and host connections. To get the switch up and running in our lab environment, we make a number of changes from the stock shipping configuration, which in most cases is a blank switch.

In the Lab: On-Site Testing Toolkit
At StorageReview, almost all reviews on the site are tested with hardware in our own lab on-premises in Cincinnati. As we grow and expand to testing larger storage systems, the need for proper on-site testing equipment grows. Rather than use gear supplied by a vendor for in-lab visits, we prefer to keep as much control as possible in these environments to ensure data reliability. Of course taking our lab on the road isn't possible, so we've endeavored to create the next best thing, a mini-lab built around an EchoStreams Innovative Solutions very short depth 1U dual-proc server that is easy to transport between locations.

In the Lab: Bulk SSD Secure Erasing
When reviewing large batches of SSDs for a certain project, the time always comes where to get back to a clean state, a bunch of SSDs need to be secure erased. This process can't be overlooked, since depending on the workload, not putting a drive back into its factory fresh condition can cause problems switching between workloads. In this lab tip we've documented how to secure erase SSDs by streamlining the process. We've created bulk erasing scripts for Linux server environments, which handle up to 23 SSDs at a time in a Supermicro SuperStorage Server 2027R-AR24NV.
