![]() ![]() In 12U they probably only have six controllers in three HA pairs. If I have 12KW per rack do I care If that’s 24U or 32U of kit in a 42U rack?ĭDN’s density comes at the price of having a lot of SSDs behind a small number of controllers. They run out of power and cooling at each rack long before all the rack slots are filled. ![]() When the Ceres box gets 60TB SSDs later in the year, that rackspace total will drop to 5 x 1.6PB 1RU enclosures plus 4RU for the controllers again – 9RU in total and just one more than DDN.Ī VAST source suggested that arguing about who can fit the most flash in a rack unit doesn’t make any more sense than arguing over how many angels can dance on the head of a pin because customers don’t care. A VAST Data Ceres-based system would need 10PB for 10 x 807.8TB 1 RU storage enclosures and, say, 4U more for 4 x CNodes (Controller nodes), making 14RU in total. He added that DDN provides “50x more IOPS/RU, 10x more writes/rack and 6x more capacity/watt.”ĭDN says its EXAScaler can provide up to 8PB in 12 RU of space. Kuckein told his audience that “DDN gives you 39x more writes per RU than a prominent newcomer to Nvidia data supply,” without naming the newcomer. It claims that its Universal Storage system is the first enterprise network-attached storage (NAS) system approved to support the Nvidia DGX SuperPOD.ĭDN’s customers, however, also include data-intensive organizations and enterprises. Startup VAST Data has been showing off its SuperPOD credentials by announcing that Nvidia has certified its QLC flash array as a SuperPOD data store. DDN says that, with large language model work, compute overlaps data transfer and faster transfer means compute completes faster. These 12 appliances also provide 780GBps writes. Review the FAQs for additional information.There is linear scaling to 900GBps reads from 24RU of storage – 12 x A1400X2 appliances with 90GBps/appliance.
