Demartek has a collection quad-processor, dual-processor and single-processor rack and blade servers, some having 60 or more cores, and up to 1.5 TB of memory in these servers, making them suitable for a wide variety of storage stress testing, virtualized server environment testing and for testing real-world applications such as Microsoft Exchange Server, SQL Server, SharePoint Server, Oracle database and more.
In September 2017, we received the first wave of servers with Intel® Xeon® Scalable (“Skylake”) processors in what are also known as “Purley” platforms, with more expected to arrive in the Demartek lab in October 2017. These servers, along with one we have from the prior generation, support NVDIMM memory technology. Also, in late 2017, we began to receive servers with the AMD EPYC™ processors. In December 2014, we added an eight-node cluster of servers to perform Hadoop and other distributed computing and storage platform testing.
The Demartek lab is equipped with Ethernet switches that have many ports of 1Gb Ethernet (1GbE), 10Gb Ethernet (10GbE), and several ports of 40Gb Ethernet (40GbE). We recently added a new 25GbE/100GbE switch that supports the new speeds of Ethernet. For 10GbE, we have both 10GBASE-R (SFP+) and 10GBASE-T (RJ45) switches and adapters. The 25GbE ports are SFP28. The 40GbE ports are QSFP+ and the 100GbE ports are QSFP28.
Demartek has appropriate copper and fiber optic cables for 1GbE, 10GbE, 25GbE, 40GbE and 100GbE. Demartek runs typical TCP/IP network and file server traffic, in addition to FCoE and iSCSI traffic. Demartek has 1GbE, 10GbE, 25GbE, 40GbE and 100GbE NICs, iSCSI offload adapters and FCoE CNAs. Some of the NICs support SR-IOV, RoCE (RDMA over Converged Ethernet) and/or iWARP.
Demartek has 32Gb, 16Gb and 8Gb Fibre Channel switches in its lab, along with 32Gb, 16Gb and 8Gb Fibre Channel HBAs and the appropriate fiber optic cables and transceivers (optics).
Demartek has 12Gb, 6Gb and 3Gb SAS HBAs and RAID controllers, including SSD caching versions. Demartek also has a SAS switch in its lab.
Demartek has a variety of direct attached storage (DAS), network attached storage (NAS) and storage area network (SAN) storage systems. The NAS and SAN storage systems connect via various speeds of Ethernet and Fibre Channel (see above). For DAS, we have a 60-drive JBOD available for testing that supports 3.5-inch (LFF) and 2.5-inch (SFF) SAS and SATA drives.
NVMe and NVMe over Fabrics
Demartek has a variety of NVMe devices (drive form factor and add-in-card form factor) that can be deployed in some of the servers. In addition, we have configured complete end-to-end NVMe over Fabrics (NVMe-oF) configurations using both RDMA (RoCE) and Fibre Channel. In our NVMe-oF testing, we have observed potential sources of bottlenecks, which we describe in our NVME over Fabrics Rules of Thumb commentary page.
Demartek has a electric power meters to measure electric power consumption of servers, network and storage equipment. For precise electrical power measurement, A/C sources are used to provide power with very tight tolerances for voltage and harmonic distortion.
We have a loading dock for receiving freight shipments.
ISO 17025:2005 Accreditation
In December 2013, Demartek was awarded International Standard ISO/IEC 17025:2005 accreditation as an electrical testing laboratory. In November 2015, and again in November 2017, Demartek’s accreditation was renewed.
ISO 17025:2005 is the international standard by which a laboratory’s commitment to quality is evaluated. Demartek achieved this accreditation by demonstrating technical competence for electrical energy efficiency testing of data center storage equipment with the operation and effectiveness of its laboratory. ISO 17025:2005 not only considers management and technical expertise, but also emphasizes continual product and process improvement.
ISO 17025:2005 accreditation is an important step in Demartek’s strategy to offer energy efficiency testing for data center storage and related data center equipment. Demartek’s strong experience with deploying and running data center storage equipment from a variety of manufacturers, combined with our interest in data center energy efficiency and power consumption puts us in the unique position of performing these energy efficiency tests in our lab in a seasoned, consistent manner.

The EPA ENERGY STAR Data Center Storage taxonomy is consistent with the taxonomy developed by the Storage Networking Industry Association (SNIA) Green Storage Initiative as defined in the SNIA Emerald™ Power Efficiency Measurement Specification. Demartek is an official SNIA Emerald™ Recognized Tester (see above).
Demartek presented at the first SNIA Emerald Power Efficiency Class in June 2013, and at the second class held in July 2014. We are skilled at finding the “best foot forward” (optimum) configuration for storage systems under test.
Demartek ENERGY STAR Datacenter Storage Certification Process
Experienced Storage Administrators
We have several years of experience deploying and running storage systems from major storage system manufacturers including EMC, NetApp, HP, IBM, Nimbus Data and others in our lab. We frequently run end-to-end validation and performance tests, configuring these storage systems into our server and networking infrastructure, and many of the results of these tests are public and available on our news page.
We have found that most modern storage systems have power supplies that support 100-250v, and perform most efficiently at 230v or 240v. However, we can run the EPA ENERGY STAR Data Center Storage tests at 115v, 120v, 230v, 240v or any other voltage required. We use A/C sources in our lab to guarantee a tight tolerance on voltage and related parameters, as required by the EPA ENERGY STAR Data Center Storage specification.
Parallel Test Execution
We have enough server and related infrastructure to run EPA ENERGY STAR Data Center Storage tests in parallel for multiple models of storage systems, which can help accelerate achieving the ENERGY STAR label.
