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.

Tracking down noisy neighbors

Good post by Frank Denneman (thank you)

A big part of resource management is sizing of the virtual machines. Right-sizing the virtual machines allows IT teams to optimize the resource utilization of the virtual machines. Right sizing has become a tactical tool for enterprise IT-teams to ensure maximum workload performance and efficient use of the physical infrastructure. Another big part of resource management is keeping track of resource utilization, some of these processes are a part of the daily operation tasks performed by specialized monitoring teams or the administrators themselves. Service Providers usually cannot influence the right sizing element, therefor they focus more on the monitoring part.

vSphere tackles the Hyperconverged Infrastructure World: VMware VSAN 6.2

Good Post by W. Curtis Preston (thank you)

VMware is releasing VSAN 6.2, the third major release of VSAN since its introduction in August of 2014. (Like other VMware companion products, the release number is tied to the vSphere release number it is associated with.) This release gives vSphere most if not all of the major features found in other hyperconverged infrastructure products.

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.

Network, your next big storage problem!

data

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.

SMR Drives: Are they too late to the game?

smr2

Good post by Petros Koutoupis (thank you)

The sudden popularity over NAND Flash has spelled doom for traditional magnetic Hard Disk Drives (HDD). For years we have been hearing how HDDs are reaching the end of their life. We have also heard the same about Tape drives, long before that. Although, it would seem that the prediction on HDDs may become a bit more of reality, sooner than expected.

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.

Peak Fibre Channel

out_of_the_fog_by_luethy-d7thzdf

Good post by Tony Bourke (thank you)

There have been several articles talking about the death of Fibre Channel. This isn’t one of them. However, it is an article about “peak Fibre Channel”. I think, as a technology, Fibre Channel is in the process of (if it hasn’t already) peaking.

There’s a lot of technology in IT that doesn’t simply die. Instead, it grows, peaks, then slowly (or perhaps very slowly) fades. Consider Unix/RISC.

Post by Joseph Griffiths (thank you)

A good friend recently reviewed the what’s new in vSphere 6 course and has some questions.  That generated a number of really great discussions and this blog article.   At about the same time I had a customer asking why their virtual machine was showing ballooning even thou there was no memory pressure.   This generated some research and though organization into this article
