A few advices that will make your VDI sizing easier

Server virtualization helped businesses increase productivity and efficiency of their IT infrastructures by abstracting physical servers’ workloads from the underlying hardware with little to no loss of functionality, VDI applied quite the same logic. Desktops and applications run inside virtual machines that are hosted centrally, either on a server or in the cloud. The purpose of VDI is to deliver fully-featured user desktops to a variety of devices including conventional PCs, thin clients, and even zero-client endpoints. But how something that was seen as a bright alternative to the traditional server-based computing model used by Citrix and Microsoft Terminal Services a decade ago ended up being a niched deployment?

How is NVMe-oF doing? Part 1: Linux NVMe-oF Initiator + Linux SPDK NVMe-oF Target

NVMe is quite a promising technology that becomes more and more prevalent in IT environments of any size. PCIe SSDs deliver awesome performance, low latencies… still, they are far too expensive. Anyway, money, in this case, seems a problem of secondary importance. The main reason why many have not added NVMe drives to their servers yet is inability of this storage media to be presented effectively over the network: iSCSI seems to be inefficient for flash, so it is an issue. Solution? NVMe over Fabrics (NVMe-oF or NVMf, how it was called before) – the protocol created to present NVMe flash over the network!
