Why Docker is the new VMware

Good post by Erwin van Londen (thank you)

Server virtualisation is the result of software development incompetence

Yes, it has given me some grief given the fact 99% of respondents did not read beyond the title and made false assumptions saying I accused these developers for being stupid. Tough luck. You should have read the entire article.

How do I get to the next level?

Very good post by Duncan Epping (thank you)

Every week I get an email from someone asking if I can mentor them, if I can help them get to the next level, if I can help them become a VCDX, if I can explain to them what I did to progress my career. I figured I would write an article for those who wonder what I did, this is not a magic formula by any means, following the same path and putting in the same amount of effort is no guarantee for success. There is also that thing called “being at the right place, at the right time” and of course seeing opportunities, grabbing opportunities and taking risks.

What are IOPS and should you care?

Post by George Crump (thank you)

When evaluating a new storage system, especially an all-flash array, the number of IOPS (Inputs/Outputs per Second) that the storage system can sustain is often used to differentiate one storage system from another. But is this really a standard that has any merit given the demands of today’s data center and the capabilities of today’s storage systems?

There are three factors that when combined tell the full story of storage performance; bandwidth rate, latency and IOPS. Most storage vendors tend to focus on IOPS to brag about how fast their storage system is. But measuring storage system performance by IOPS only has value if the workloads using that storage system are IOPS demanding.

vSphere Virtual Volumes Interoperability: VAAI APIs vs VVOLs

Good post by Rawlinson Rivera (thank you)

In 2011 VMware introduced block based VAAI APIs as part of vSphere 4.1 release. This APIs helped improving performance of VMFS by providing offload of some of the heavy operations to the storage array. In subsequent release, VMware added VAAI APIs for NAS, thin provisioning, and T10 command support for Block VAAI APIs.

Now with Virtual Volumes (VVOLs) VMware is introducing a new virtual machine management and integration framework that exposes virtual disks as the primary unit of data management for storage arrays. This new framework enables array-based operations at the virtual disk level that can be precisely aligned to application boundaries with the capability of providing a policy-based management approach per virtual machine.

Archiving with HP StoreAll Storage: An answer to rampant unstructured data growth

Post by Stephen Bacon (thank you)

A frequently cited challenge by large organizations is the rampant growth of unstructured data. In the past, a common response has been to simply throw more primary storage at the problem. However, that’s usually a temporary bandage at best and wholly ineffectual at worst.

A closer look at SpringPath

Good post by Cormac Hogan (thank you)

Another hyper-converged storage company has just emerged out of stealth. Last week I had the opportunity to catch up with the team from SpringPath (formerly StorVisor), based in Silicon Valley. The company has a bunch of ex-VMware folks on-board, such as Mallik Mahalingam and Krishna Yadappanavar. Mallik and Krishna were both involved in a number of I/O related initiatives during their time at VMware. Let’s take a closer look at their new hyper-converged storage product.

Orchestrating Copy Data

Post by George Crump (thank you)

2015 will be THE year of copy data management. Multiple vendors will bring solutions to the market. Many of these solutions will leverage snapshot technology in one form or another in an effort to reduce the capacity requirements of secondary data copies needed to drive data protection, business analytics, and test/dev operations. But there is another key resource that needs to be saved; time. Copy data solutions need to provide a high level of orchestration and analysis so that system administrators can be more efficient and decrease the chance for error.

Musing: Who Cares About FCoE in 2015 ?

Good post by Greg Ferro (thank you)

While I continue to scratch my head about who is foolish enough to actually deploy FCoE, perhaps a more important question is which vendors care about it ?

Answer ? Brocade and Cisco.

vSphere 6.0 Storage Features Part 5: Virtual Volumes

Good post by Cormac Hogan (thank you)

I pushed this post out a bit as I know that there is a huge amount of information out there around virtual volumes already. This must be one of the most anticipated storage features of all time, with the vast majority of our partners ready to deliver VVol-Ready storage arrays once vSphere 6.0 becomes generally available. We’ve been talking about VVols for some time now. Actually, even I have been talking about it for some time – look at this tech preview that I did way back in 2012 – I mean, it even includes a video! Things have changed a bit since that tech preview was captured, so let’s see what Virtual Volumes 2015 has in store.

Understanding Software Defined Storage

Very good post by Pushpesh Sharma (thank you)

Storage systems are essential to the data center. Given the exponential rate of data growth, it is increasingly becoming more and more challenging to scale the enterprise storage infrastructure in a cost effective way.

Storage technology over the years has seen incremental technology advancements. The early days of enterprise storage were mainly direct-attached storage (DAS) with host bus adapters (HBAs)  and redundant array of independent disks (RAIDs.) The DAS advanced by more faster and more reliable protocols like ATA over Ethernet(ATA), serial attached technology adapters (SATA), external serial attached technology adapters (eSATA), small computer system interface (SCSI), serial attached SCSI (SAS), and fibre channel.
