What’s All The Fuss About Hyper-Converged Infrastructure?

Post by Anita Kibunguchy (thank you)

Technology has made it so easy that customers looking to purchase a product or service need to simply look online for reviews. Did you know that 80% of people try new things because of recommendations from friends? It’s the reason why e-commerce companies like Amazon have thrived! Customers want to hear what other customers have to say about: The product, their experience with the brand, durability, support, purchase decisions, recommendations … the list goes on. This is no different in the B2B space. That is why IT Central Station is such an invaluable resource for customers looking to adopt new technologies like hyper-converged infrastructure (HCI) with VMware Virtual SAN. Customers get a chance to read unbiased product reviews from the tech community which makes them smart and much more informed buyers.

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.

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.

Data Retention for Dummies

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

All is confusion. The old certainties are gone. New certainties just don’t exist. The shifting shapes, players, products and technologies in the storage landscape are seen through fog. How the heck does everything fit together?

After four days in Silicon Valley meeting startups the bewilderment ratio us even higher. It’s like Dragons’ Den, where each new player is shinier and brighter than the previous one, becomes your favourite but then, as sure as eggs are eggs, will be eclipsed by the next one.

Good post by Vladan Seget (thank you)

I somehow ignored this information but I think that it’s very useful to share, especially if you’re navigating the SMB or very SMB sector. In fact VMware VSAN for ROBO Two Node 10 GbE cross-connect support. So you have the possibility to cross connect ROBO nodes, via low cost 10GbE option and have a great performance because you’ll have dedicated VMkernel interface for VSAN traffic.

New Microsoft Exchange 2013 on Virtual SAN 6.1 Reference Architecture

Good post by Rawlinson Rivera (thank you)

A new Microsoft Exchange 2013 on Virtual SAN 6.1 is now available on the VMware Virtual SAN product Resource page.

This new VSAN-Exchreference architecture walks through the validation of Virtual SAN’s ability to support Microsoft Exchange 2013 designed to satisfy high IOPS mailbox configuration with Exchange Database Availability Groups (DAGs). The reference architecture is based on a resilient design that covers VMware vSphere clustering technology and Exchange DAG as well as data protection and recoverability design of Exchange Server 2013 with vSphere Data Protection and vSphere Site Recovery Manager.

Where VSAN doesn’t shine: Sources explain EMC’s ScaleIO purpose

Good post by Chris Mellor (thank you)

EMC introduced its scale-out ScaleIO Node virtual SAN a couple of weeks ago, with hybrid flash-disk and all-flash server chassises. It overlaps as a product with EMC-owned VMware’s VSAN, and therefore EMC’s EVO:RAIL implementation of that, and also competes with scale-out all-flash arrays.

Discussions with sources have clarified EMC’s thinking on the topic, and showed that the overlap is less than originally thought.

A closer look at the VSAN witness appliance

Good post by Cormac Hogan (thank you)

As part of the Virtual SAN 6.1 announcements at VMworld 2015, VMware announced two new, eagerly anticipated features. The first of these is VSAN stretched cluster, allowing you to protect your virtual machines across data centers, not just racks. And the second is 2-node VSAN, which will be an excellent solution for remote office/branch office (ROBO) configurations.
