Cisco UCS X-Sequence – 100G Unified Material for storage

Because the starting, one of many key differentiators for Cisco UCS has been Unified Material. The flexibility to have a community adapter (VIC) and Material Interconnect help knowledge, storage, and administration visitors. This offers a less complicated atmosphere for server I/O needing fewer adapters, cables, and switches. Moreover, we’ve got supported equipment ports on our Material Interconnects for the reason that first technology. An equipment port permits you to instantly connect with Ethernet storage without having a further change. The Material Interconnect can change a number of Ethernet and Fibre Channel switches which has each a TCO and sustainability affect (fewer issues to purchase, get rid of, energy, cool, and keep).


Maximize efficiency and effectivity with digital networking

A vNIC is a virtualized community interface that’s configured on a bodily VIC adapter and seems to be a bodily NIC to the working system of the server. A vHBA equally is a virtualized host bus adapter for Fibre Channel storage that additionally makes use of a VIC. A single bodily adapter could be carved up into many digital adapters. Why would you wish to do that? Not each software wants 100G of bandwidth itself. However with virtualization, having quite a lot of I/O bandwidth brings benefits. A single bodily VIC could be carved up into many digital adapters. I might need 4 10G Ethernet vNICs and two 16G Fibre Channel vHBAs and never even be at my most bandwidth. You get to determine what number of of which varieties of digital adapters finest meet your wants. Every digital adapter may also have its personal QoS so you’ll be able to prioritize the visitors flows. This lets you oversubscribe the precise bodily bandwidth (e.g. 2x25G Eth + 2x32G FC) with much less affect.


Unified Material in motion

Within the first video, we’ll see a UCS X210c Compute Node utilizing vHBAs to speak to a Fibre Channel storage array. With a number of 32G FC connections, we’ll obtain virtually full line fee of 100G efficiency. And since not all storage speaks Fibre Channel, within the second video we’ll see NFS over Ethernet with vNICs obtain most efficiency.


Within the movies, we’re utilizing the open-source Versatile I/O tester (FIO) written by Jens Axboe. FIO is a versatile testing / benchmarking suite for storage.




Wrapping up

Solely Cisco unifies networking and computing in a means that works for each server and community admins. We offer scale, aggregation, and manageability in a means that simplifies operations for IT. Unified Material offers each CapEx (fewer adapters, switches, and cables) and OpEx (energy & cooling reductions and fewer time spent managing the {hardware}) advantages that assist your organization.


As networking speeds enhance, the modularity and future proofing of X-Sequence turns into much more essential. We launched X-Sequence with 25G 4th Gen Unified Material. Now it’s 100G 5th Gen. With no midplane, the X9508 Chassis and X-Sequence are able to evolve to 400G and past .
