Why We Love to DASH (And You Should, Too!)

Post by Brian Mitchell (thank you)

Nobody likes slow backups.

Take, for example, “Synthetic Full” backups. This type of backup allows for the creation of a new “full” backup image by combining a previous full backup with the associated incremental backups – essentially implementing an “Incremental Forever” strategy.

Generally speaking, a synthetic full means less time is needed to perform a backup and system restore times are reduced.

Microsoft’s Scale-Out File Server Overcomes SAN Cloud Barriers

Good post by Paul Schnackenburg (thank you)

There are no SANs in the cloud because the venerable storage technology just doesn’t scale to that level. But there are ways around it, and Microsoft shops should start with the company’s Scale-Out File Server.

There’s a revolution going on in storage. Once the domain of boring but dependable storage-area network (SAN) arrays, there’s now a plethora of choice, including all flash storage (with varying different underlying technology) and server-message block (SMB)-based storage.

HP Storage and Veeam integration demo

Good post by Calvin Zito (thank you) on HP BURA and Veeam

It’s BURA Sunday and normally I have my team of experts doing these posts on Sunday but this week, they needed a break. The timing was perfect because I just finished editing a video demo that I did when I was at VeeamOn a few weeks ago.

The demo shows the integration between HP Storage – StoreVirtual, 3PAR StoreServ, StoreOnce, and StoreEver – to use snapshots for high availability, backup and archive.  Here’s a summary of that:

  • Instant recovery from StoreVirtual and 3PAR of virtual machines, files and more
  • Backup to disk and offsite replication (for disaster recovery) to StoreOnce
  • Archive backup to StoreEver tape for longer term retention.

Performance buffers for Brocade ISLs


Good post by Sebastian Thaele (thank you)

Sometimes we notice that an ISL is actually a bottleneck in a fabric. Not a congestion bottleneck where the throughput demand is just too high for the ISL’s bandwidth. This one could be solved by putting another cable between the both switches. But if you have a latency bottleneck your ISL won’t be running at the maximum of the bandwidth. The contrary is the case: it lacks the buffer credits to ensure a proper utilization. If you see a latency bottleneck on an ISL it’s often back pressure from a slow drain device attached to the adjacent switch. But every now and then I get a case where it’s just the ISL. Sometimes in one direction, sometimes in both. Even with lengths were you don’t think about using long distance settings at all.

What is coming for vSphere and VSAN? VMworld reveals…

Good Post by Duncan Epping (thank you)

I’ve been prepping a presentation for upcoming VMUGs, but wanted to also share this with my readers. The session is all about vSphere futures, what is coming soon? Before anyone says I am breaking NDA, I’ve harvested all of this info from public VMworld sessions. Except for the VSAN details, those were announced to the press at VMworld EMEA. Lets start with Virtual SAN…

The Virtual SAN details were posted in this Computer Weekly article, and by the looks of it they interviewed VMware’s CEO Pat Gelsinger and Alberto Farronato from the VSAN product team. So what is coming soon?

X-IO: Zero Maintenance, Low Latency, VDI Storage

Post by Marco Broeken (thank you)

At VMworld Barcelona, I was invited by Stephen Foskett to join the #TFDx event (short for Tech Field Day Extra). I’m writing about X-IO because their presentation actually triggered me. They handle a lot of things very differently. And as you can read below, I like how they do that.

HP Labs and the Future of Technology

What if you could release 4TB of storage in every 10TB with no business impact?

Good post by Andrew Dickerson (thank you)

What a waste of space!

If you’re responsible for data storage, you already know that storing and managing more than 30% annual data growth is eating up your budget faster than just about anything else in IT. In fact, industry analysts estimate that anything between 25% and 40% of the total IT budget will be spent on storage in 2014.

Now’s the time for hyper-convergence

Post by Kate Davis (thank you)

The New Style of IT is an opportunity for change – change to propel your business, to prepare for what may come, to make environments more efficient and simplified.

One of the ways we’ve been enacting change for our customers is through convergence – a move to bring the components of the data center closer together by simplifying management, optimizing workloads and increasing efficiency.

Short stroking disk drives to improve performance

Good Post by Erwin van Londen (thank you)

Reading a post from Hans DeLeenheer (VEEAM) which ramped up quite a bit including responses from Calvin Zito (HP), Alex McDonald (NetApp) and Nigel Poulton. The discussion started on a comment that XIO had “special” firmware which improved IO performance. Immediately the term “short-stroking” came up which leads to believe X-IO is cheap-skating on their technologies. I was under the same impression at first right until the moment I saw that Richard Lary is (more or less) the head of tech at X-IO together with Clark Lubbers and Bill Pagano who also come out of that same stable.
