An overview of the new Virtual SAN 6.2 features

Good Post by Cormac Hogan (thank you)

If you were wondering why my blogging has dropped off in recent months, wonder no more. I’ve been fully immersed in the next release of VSAN. Today VMware has just announced the launch of VSAN 6.2, the next version of VMware’s Virtual SAN product. It is almost 2.5 years since we launched the VSAN beta at VMworld 2013, and almost 2 years to the day since we officially GA’ed our first release of VSAN way back in March 2014. A lot has happened since then, with 3 distinct releases in that 2 year period (6.0, 6.1 and now 6.2). For me the product has matured significantly in that 2 year period, with 3,000 customers and lots of added features. VSAN 6.2 is the most significant release we have had since the initial launch.

Protecting Compliance in the Public Cloud

Post by Christine Taylor (thank you)

When it comes to compliance, different regulations exist for different industries. For example, the Health Insurance Portability and Accountability Act (HIPAA) is the granddaddy of healthcare-related compliance. Payment Card Industry Data Security Standard (PCI DSS) oversees the credit card industry, while Sarbanes–Oxley (SOX) regulates the reliability of financial reporting by public companies and their accounting firms. The Gramm-Leach-Bliley Act (GLBA) administers a large set of compliance regulations for banks, investment institutions and insurance firms. And there are many more including US–EU Safe Harbor, ISO, FDA and a whole set of federal regulations around information processing, security management and risk management.

More data services in VSAN 6.2

Good Post by Andrea Mauro (thank you)

As announced some months ago, the new Virtual SAN (VSAN 6.2) will add new data services making this solution more rich that before. Version 6.1 was announced during the last VMworld editions with some interesting features, including a ROBO scenario.

But was still limited in data service: better snapshot technologies, better VMFS, but still some limits and no deduplication, no compression, no erasure coding at all.

Traffic Isolation Zoning – The mistake of FOS

Good post by Erwin van Londen (thank you)

If there is one thing I would consider “the” blunder of FOS engineering it has to be Traffic Isolation zoning. I mean, creating such an administrative nightmare with obscure directions causing confusion and nasty pitfalls when one thing goes wrong is in many occasions a recipe for disaster.

NVMe fabric flash and deduping VSAN lead

The Future Road Sign with dramatic clouds and sky.

Good post by Chris Mellor (thank you)over at El Reg

EMC has new storage products coming in both external shared array form and in its converged and hyper-converged systems lines of products, using new VSAN capabilities.

These will be announced over the next two quarters and will change the shape of EMC’s product lines. We think we now have an overall view of what the mainstream product lines will look like.

This information comes from EMC’s latest quarterly results earnings call, from various sources, and from blogs by EMC VCE president Chad Sakac.

The background includes the point that VMware’s VSAN/EVO:RAIL/EMC VSPEX Blue products have not apparently been successful, hence the need for a revamp of the core VSAN software.

Good post by Lazlo Creates (thank you)

Just like any other area of technological innovation, cloud is a massive industry which has developed in ways few would predict a couple of years ago. As more individuals and enterprises embrace cloud technologies, the security and usability questions become a central focus of many providers. But consumer expectations aren’t the only factor shaping the state of cloud. Here are 10 key cloud trends to watch in 2016.

Making All-Flash 3D TLC SSD Arrays Enterprise Ready

3d-nano-ssd-rcm992x0

Good post by George Crump (thank you)

All-Flash Array Vendors are now releasing systems with 3D TLC SSDs. They claim that they have reached price parity, without data efficiency, to mainstream data center hard disk arrays. 3D TLC NAND does bring the price per GB of flash storage down considerably, but it does carry the risk of device failure and data loss. Understanding how a vendor mitigates that risk is critical to vendor selection.

Network, your next big storage problem!

Good post by Enrico Signoretti (thank you)

A few days ago I had an interesting chat with Andy Warfield at Coho Data and the topic of Network/Storage relationship came up several times. (Quick disclaimer: I’m currently doing some work for Coho)

In a couple of my latest articles (here and here) I talked about why many large IT organizations prefer PODs to other topologies for their datacenters but I totally forgot to talk about networking (I also have to admit that networking is not my field at all). So, this article could be the right follow-up for those posts.

HPE tops IDC’s all-flash array list. But look who’s not on the list

Good post by Chris Mellor (thank you) over at El Reg

Severely narrow view of AFA industry

Research house IDC has put out an all-flash array marketscape which deliberately excludes most of the available all-flash arrays. HPE tops its AFA list.

IDC identifies three leaders:

  • EMC with its XtremIO product
  • HPE with its 3PAR 7450c
  • Pure Storage and its FlashArray //m

Can we put them in a 1-2-3 order?

Network change – who is in control?

Post by John Harrington (thank you)

Network Change

Nothing sparks engineering debate quite as much as ‘network change control’. It’s one of those topics we love to hate. We feel buried by useless bureaucracy. We ask, ‘Why can’t our managers just trust us, instead of weighing us down with meaningless process and red tape’?
