Future of Data Storage: 8 Technologies Changing Storage

Good post by Paul Rubens (thank you)

Data storage is undergoing dramatic evolution, in the near, medium and long term. The following new disk, solid state and tape storage technologies will offer enterprises cheaper, faster and more energy efficient storage.

Near term:

1) Ethernet hard drives
Seagate recently announced its Ethernet-connected Kinetic HDD, which the company claims will offer storage application performance that’s four times greater than now possible.

In a Battle of Hardware, Software Innovation Comes Out On Top

Good post by Joy Das (thank you)

Database appliances, as well as servers configured for databases, need a smart and simplified combination of hardware and software that supports performance, scale and ease of management. And if your business is committed to building the fastest database appliances in the market, like Alex Alexander and SpringbokSQL, then you need to constantly be testing the various building blocks of the complete IO stack to ensure they are truly the fastest in the world.

Will the “Tape is Dead” Folks Please Sit Down?

Post by Christine Taylor (thank you)

A storage newsletter that shall go unnamed (we all make mistakes) discussed the dwindling of tape in 2012. Their opinion was that tape was on its way out. They pointed out that backup was moving to VTLs and that this change would be the death knell of tape.

The article granted archiving as a use case but questioned tape’s reliability over disk, and questioned tape’s slower access numbers over disk. Finally, the article reported that the only tape maker that was sharing numbers was SpectraLogic because news at other tape vendors was not good.

Should you be able to turn All-Flash Deduplication off?

Good post by George Crump (thank you)

Deduplication, along with compression, provides the ability to more efficiently use premium priced flash capacity. But capacity efficiency comes with at least some performance impact. This is especially true on all-flash arrays where data efficiency features can’t hide behind hard disk drive latency. This has lead some all-flash vendors, like Violin Memory, to claim that an on/off switch on all-flash should be a requirement. Is that the case?

Slow backup of VM on VSAN Datastore

Good post by Duncan Epping (thank you)

Someone at out internal field conference asked me a question around why doing a full back up of a virtual machine on a VSAN datastore is slower then when doing the same exercise for that virtual machine on a traditional storage array. Note that the test that was conducted here was done with a single virtual machine. The best way to explain why this is is by taking a look at the architecture of VSAN. First, let me mention that the full backup of the VM on a traditional array was done on a storage system that had many disks backing the datastore on which the virtual machine was located.

FLASH better than DISK for archiving, say academics.

Post by Chris Mellor (thank you) over at El Reg

An academic paper claims flash could be better than disk for archiving. So just how did this unlikely result come about?

The SSRC* paper, An Economic Perspective of Disk vs. Flash Media in Archival Storage, was published earlier this year, at the 22nd IEEE International Symposium on Modelling, Analysis, and Simulation of Computer and Telecommunication Systems (MASCOTS 2014).

In it, lead author Preeti Gupta and her colleagues found that “archives based upon alternative media [such as flash] are surprisingly cost competitive [when compared with] archives based upon traditional disk media over the long-term”.

New flash features with latest HP 3PAR OS 3.2.1

Good post by Clavin Zito (thank you)

Looking back at the blog for the last week and I’ve had other subject matter experts writing blogs so I thought today’s news would be a perfect chance for me to jump back into the mix!

We released HP 3PAR OS 3.2.1 a few weeks ago but haven’t publicly announced what that OS release brings to HP 3PAR StoreServ. Since the enhancements are substantial, I’ll talk today at a high-level and over the next few days I’ll have some of those other subject matter experts posting articles to go deeper on some of the news.

Speed mismatch is the death-trap for shared storage

Good post by Erwin van Londen (thank you)

I’ve been focusing on the implications of physical issues a lot in my posts over the last ~2 years. What I haven’t touched on is logical performance boundaries which also cause extreme grief in many storage infrastructures which lead to performance problems, IO errors, data-corruption  and other nasty stuff you do not want to see in your storage network.

New Generation Storage Arrays

Post by Harsha Hosur (thank you)

I recently read a blog by Josh Odgers about the the requirement for hardware support specifically availability of the storage controllers or lack thereof (link:http://www.joshodgers.com/2014/10/31/hardware-support-contracts-why-24×7-4-hour-onsite-should-no-longer-be-required/). So I wanted to share my experience with storage controller availability and how modern storage systems provide availability as well as performance. I have used examples of system I have worked on extensively (XtremIO) and also other vendor technology that I read up on (EMC VMAX and Solidfire).
