TO22-Z61, TO22-Z62 AMD EPYC compute nodes, 2OU height nodes, feature dual AMD EPYC 7000 series (Naples) processor sockets, with 8 channels of memory and 8 x DIMM slots per socket (16 x DIMM slots per node).
TO22-Z61 features a flexible combination of flash and SATA storage capacity with 4 x 2.5" frontal hot / swappable SSD / HDD drive bays that can feature maximum of 2 x NVMe drives + 2 x SATA drives - or up to 4 x SATA drives instead of NVMe. SAS storage drives may also be utilized with an add-on card.
Meanwhile, TO22-Z62 offers a large capacity of all flash high performance all flash storage, with 4 x 2.5" frontal hot swappable drive bays that can feature maximum of 4 x NVMe drives - or up to 4 x SATA drives instead of NVMe, as well as adding further internal capacity with another 4 x NVMe internal 2.5" drive bays. - for a total capacity possible of 8 x 2.5" NVMe drives.
TO22-Z61 and TO22-Z62 both feature two low profile PCIe x16 expansion slots for networking or storage expansion options. TO22-Z61 also has an additional OCP PCIe x16 mezzanine slot available - the OCP slot on TO22-Z62 is occupied by a U.2 HBA expander card. Networking wise, each node features dual 1GbE LAN ports, as well as a dedicated MLAN port for remote management.
Both TO22-Z61 and TO22-Z62 are designed to slide easily into GIGABYTE's three bay, 2OU node tray - for a total density of three compute nodes per 2OU rack height: either TO20-BT1 - an OCP Version 1.0 node tray compatible with GIGABYTE's 41OU DO20-ST0 or DO20-ST1 racks or our 12OU DO60-MR0 mini-rack, or TO21-BT0 - an OCP Version 2.0 node tray compatible with GIGABYTE's 41OU DO21-ST0 or DO21-ST1 racks.
What are the Open Rack Standards? They are a set of open source hardware design guidelines initially developed by Facebook and then transformed in 2011 into an open source project. Being open source means that anyone can contribute, so a large number and variety of different organisations involved in building data centres have contributed their expertise and experience in designing hardware that is faster and easier to deploy, less expensive, and have just the right features needed for scale and efficiency, with a design primarily geared around space and power savings.
The Open Rack Standards design can achieve this in several ways. Firstly, the rack width is 21" compared with a traditional 19" rack, with a server unit height of 1OU - 1.89" compared with the 1U height of 1.75" for a traditional rack, allowing for more horizontal and vertical space in each tray for more compute, networking and storage density or for better airflow or cabling space. Secondly, the power supply for each server rackmount is removed and consolidated in a separate, central unit. This not only frees up more space for other components but also allows for better cooling and maintenance efficiency of the consolidated power supply unit. Power supply is instead supplied to compute, storage and GPU nodes directly through a "bus-bar" system running along the rear of the rack.
In addition, the server nodes are designed like Lego bricks, which are small enough to be easily handled by a single person. This also adds to the design's ease of scalability: each node is available individually and can be ordered later in time to add capacity to existing infrastructure. The Open Compute Project states that these design features were found to be 38% more energy efficient to build and 24% less expensive to run than traditional 19" rack infrastructure for the first adopters of the Open Rack Standards.
GIGABYTE's RACKLUTION-OP OCP rack solutions product line-up features two different power supply designs based on two different versions of the Open Rack Standards: OCP Version 1.0 is a rack design that features power supply via three vertical 12V bus-bars, while OCP Version 2.0 is a rack design where power is supplied via a single vertical 12V bus-bar only. Each bus-bar connector can directly supply up to 960W (80A x 12V), therefore an OCP Version 1.0 rack (three bus-bars) can supply up to 2,880W per shelf (960W x 3 bus-bar connectors), making it suitable for a rack with GPU nodes that have heavy power consumption requirements, while an OCP Version 2.0 rack (single bus-bar) can supply up to 480W per node, making it a more cost efficient choice for compute and storage nodes where power requirements are not as heavy. Both versions co-exist with each other and customers can chose their design based on their specific system requirements.
GIGABYTE continues to lead the way in providing its data centre customers a range of innovative solutions to reduce their CAPEX and OPEX, and its RACKLUTION-OP product line is an important part of this offering.
