Samsung announced its 960 PRO and 960 Evo, the next generation M.2 PCIe SSDs. Like the 950 Pro, the 960 Pro and 960 Evo are PCIe 3.0 x4 drives using the latest NVMe protocol for data transfer. The 960 Pro offers a peak read speed of 3.5GB/s and a peak write speed of 2.1GB/s, while the Evo offers 3.2GB/s and 1.9GB/s respectively. The 950 topped out at a mere 2.5GB/s and 1.5GB/s.

The 960 Pro and the 960 Evo are planned for release in October. The Pro starts at $329 for 512GB of storage, rising up to a cool $1,299 for a 2TB version. The Evo price goes from $129 for a 250GB version to $479 for a 1TB version.

Is NVMe Really Revolutionary?
Posted by Jon Toigo on August 19, 2016
4/5 (1)

To hear advocates talk about NVMe – a de facto standard created by a group of vendors led by Intel to connect flash memory storage directly to a PCIe bus (that is, without using a SAS/SATA disk controller) – it is the most revolutionary thing that has ever happened in business computing.  While the technology provides a more efficient means to access flash memory, without passing I/O through the buffers, queues and locks associated with a SAS/SATA controller, it can be seen as the latest of a long line of bus extension technologies – and perhaps one that is currently in search of a problem to solve.

I am not against faster I/O processing, of course.  It would be great if the world finally acknowledged that storage has always been the red-headed stepchild of the Von Neumann machine.  Bus speeds and CPU processing speeds have always been capable of driving I/O faster than mechanical storage devices could handle.  That is why engineers used lots of memory – as caches ahead of disk storage or as buffers on disk electronics directly – to help mask or spoof the mismatch of speed.

Seagate introduces 60TB SSD drive
Posted by Oksana Zybinskaya on August 16, 2016
5/5 (1)

Seagate shows off two new SSD products: an 8TB NVMe drive and a spacious 60TB SSD prototype in a 3.5-inch form factor.

This 60TB consists of more than a 1,000 Micron 3D NAND dice fitted into a full-size, 3.5-inch disk form factor package. Apparently, it has dual port 12Gbit/s SAS interface and 150,000 random read IOPS, with undisclosed write IOPS. The sequential read/write numbers should be 1.5 and 1.0GB/sec.

Choosing ideal mini server for a home lab
Posted by Askar Kopbayev on August 11, 2016
5/5 (4)

Yesterday I saw a blog post in Homelab subreddit discussing what Intel NUC to choose. I have spent quite some time recently to choose the right server for my homelab expansion and I have considered a lot of options.

I was also looking at Intel  NUC as many other fellow IT professionals, but luckily last month I read on Tinkertry.com that Supermicro had just released new Mini-1U SuperServers – SYS-E300-8D and SYS-E200-8D.  I had some discussions with my colleagues and other people on Reddit and TinkerTry and I came to the conclusion that if you are aimed to run home lab for virtualization Intel NUC shouldn’t be considered. I believe SuperMicro is a new king on the market of mini servers for home lab.

The Kilocore chip represents a step change in CPU power and efficiency.

The significant increase in computing power over the past decades gave way to the most of todays advances in science and technology, such as artificial intelligence, secure global communications, or large-scale pharmaceutical analyses.

Comparing vSphere Distributed Switch and Cisco Nexus 1000v switch
Posted by Askar Kopbayev on July 7, 2016
5/5 (1)

When time comes to deciding whether to go with vSphere Distributed Switch or Cisco Nexus 1000v it is hard to tell which product is superior and you find many different and quite contradictory opinions.

While quite often it is the political decision based on the answer to the question “Who is going to manage the virtual networking?” there are many other aspects you, as an infrastructure designer, should be aware of.

Recently VMware announced End of Sale of Nexus 1000v which caused some confusion amongst clients. I know customers who were pretty sure Cisco discontinued Nexus 1000v, but rest assured, Cisco is still fully committed to continue development of virtual networking and to support Nexus 1000v in the latest and future versions of vSphere.

Google announced that its FASTER Cable system, an undersea fibre optic cable running from the US to Japan, is now online. This will give them up to 10 terabytes per second (about 1/6 of the cable’s total bandwidth). This is claimed to be the highest-capacity undersea cable ever built.

1. Introduction

With Windows Server 2016 we have gained some very welcome capabilities to do cost effective VDI deployments using all in box technologies. The main areas of improvement are in storage, RemoteFX and with Discrete Device Assignment for hardware pass-through to the VM. Let’s take a look at what’s possible now and think out loud on what solutions are possible as well as their benefits and drawbacks.
