Disk Controller features and Queue Depth?

blueprint

Good post by Duncan Epping (thank you)

I have been working on various VSAN configurations and a question that always comes up is what are my disk controller features and queue depth for controller X? Note that this is not only useful to know when using VSAN, but also when you are planning on doing host local caching with solutions like PernixData FVP or SanDisk FlashSoft for instance. The controller used can impact the performance, and a really low queue depth will result in a lower performance, it is as simple as that.

Hyperconvergence is a lazy ideal

Post by Andy Warfield (thank you) – also have a look on the comments

This blog post has generated a bunch of attention over the past few days. Much of this is because Duncan Epping felt that I was trying to FUD VMware’s VSAN.  In particular, Duncan really seems to dislike my use of the term ”lazy” here.

I’m a bit surprised at the reaction, so let me quickly clarify a couple of things and then leave my original post to speak for itself:

Fast Sideways – A connectivity point of view

blueprint

Post by Erik Smith (thank you)

Although I mentioned this functionality in a previous blog post, the impact that this type of use case will have on connectivity automation is so significant that it deserves to have it’s own post.

The first time I heard the FAST Sideways concept mentioned publicly was by Brian Gallagher during an EMC World 2013 keynote.  Brian and Steve Todd then talked about the topic in just a bit more detail during an EMCBackstage interview.  Although I believe there will be a team of folks at EMC World this year taking about this concept in general, I’ll say the following about it from a Connectivity Automation perspective.

Rethinking Enterprise Storage

Post by Colm Keegan (thank you)

With soaring data growth occurring across all industries, IT planners need to rethink how they design and implement enterprise storage technology. Traditional NAS and SAN platforms have served as the bulwark of data center storage capacity for decades, however, storing information on these premium storage assets is becoming increasingly cost prohibitive for many organizations. As a result, a new paradigm is needed to augment existing data center storage assets to more efficiently store and protect the vast amounts of information piling up across enterprise environments.

Three Key Strategies to Allocating a Data Protection Service

Post by Reliant Technologies (thank you)

Backup-to-disk is a top priority for most of the IT directors we work with. Often we find that used EMC solutions will do the trick to get a quick backup-to-disk solution in place. This may include EMC drives or NetApp drives, but could also include VNX, EMC CX4 or refurbished NetApp, depending on your environment. By backing up data and storing it in a remote location, you can ensure that in the case of natural disaster, hacking, or data corruption, they will still have the information that they need for their business.

Rant about cool new tech vs Mainframes and SPARC

Good Post by Nigel Poulton (thank you)

Attended a Blogger Briefing at Dell Enterprise Forum today. Hmmmmmm….

From the off it was obvious that Dell wanted us bloggers (all 4 of us at the entire event!) to sit watch their panel run through a scripted discussion covering topics they wanted us to hear about.  Yeah.  Pretty cheesy and obviously doomed from the start. Literally the start.  For example, the first question got me annoyed.  It went something like this (names and companies changed)

Spintronics: Not Your Typical Memory

Good Post by Kevin Fogarty (thank you)

Researchers propose new designs that rely on an electron’s spin, rather than a circuit’s electrical charge, to process information. One goal: let computers run at normal speed with little or no electricity.

A team of Japanese researchers has proposed a model for the near future of computing based on identifying a 1 from a 0 according to the direction in which an electron spins, rather than where the chip had previously stashed an electrical charge.

HP StoreOnce VSA – An introduction

Good Post by Patrick Terlisten (thank you)

A side effect of data growth is the growth of the amount of data that must be backed up. The path of least resistance is buying more disks and/ or tapes. Another possible solution is data deplucation. With data deduplication you can’t reduce the amount of data that must be backed up, but you can reduce the amount of data that must be stored. HP StoreOnce Backup is HPs solution to address this problem.

VMware Offers Disaster Recovery As A Service

Post by Charles Babcock (thank you)

VMware disaster recovery service lets customers automatically replicate business systems and data in one of VMware’s five vCloud Hybrid Service datacenters.

VMware on Tuesday launched disaster-recovery-as-a-service from its vCloud Hybrid Service’s five datacenters. For VMware customers, it will offer an integrated way to implement disaster recovery for business-critical virtualized systems without needing to contract for a physical recovery site or buy VMware’s vCenter Site Recovery Manager.
