Death by 1,000 cuts: Mainstream storage array suppliers are bleeding

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

Great beasts can be killed by a 1,000 cuts, bleeding to death from the myriad slashes in their bodies – none of which, on their own, is a killer. And this, it seems, is the way things are going for big-brand storage arrays, as upstarts slice away at the market with converged systems, virtual SANs, all-flash kit, hybrid devices, object storage, software-defined storage and the cloud.

Atlantis USX 2.0: more than Software-Defined Storage

Post by Andrea Mauro (thank you)

I’ve already write about Atlantis ILIO USX in some previous posts (for example look at the one related to Virtualization Field Day 3). Their solution is a in-memory software-defined storage solution that pools existing SAN, NAS and DAS from across the datacenter and then optimizes how server applications and VMs consume this storage.

A Tale of Two Architectures — Engineering for the 99.999% versus the 0.001%

Good Post by Rob Ren (thank you)

Today’s enterprise storage arrays follow one of five different architectural approaches to clustering their controllers for high availability.  We’ve represented them here in order of increasing complexity (from a “how difficult is it to build” perspective), robustness, and performance.

HP StoreVirtual VSA – An introduction

Good Post by Patrick Terlisten (thank you)

In 2008 HP acquired LeftHand Networks for “only” $360 million. In relation to the acquiration of 3PAR in 2010 ($2.35 billion) this was a  really cheap buy. LeftHand Networks was a pioneer in regard of IP based storage build on commodity server hardware. Their secret was SAN/iQ, a linux-based operating system, that did the magic. HP StoreVirtual is the TAFKAP (or Prince…? What’s his current name?) in the HP StorageWorks product familiy. ;) HP LeftHand, HP P4000 and now StoreVirtual.

Why is DataGravity Such a Big Deal?

Good Post by Stephen Foskett (thank you)

DataGravity just released their embargo and my little techie corner of the Internet is on fire. There’s a very good reason for that, but it might not be obvious at a glance. Read on to learn why DataGravity is a Big Deal even though it might not work out.

HP XP7 Active-Active High Availability Solution ChalkTalk

The HP XP7 Storage was introduced earlier in 2014 and now gets a very cool enhancement: Active-Active HA uses XP7 multi-array virtualization to allow active active access to virtual LUNS across two XP7 arrays. Learn more in this ChalkTalk from HPStorageGuy Calvin Zito.

Demartek Commentary — Flash Memory Summit 2014

Post by Dennis Martin (thank you)

I attended the Flash Memory Summit 2014, held in Santa Clara, California. The organizers told me that registration for this year’s annual event was approximately 5000 people, with somewhere in the vicinity of 3500-4000 people attending, which should certainly be considered a success. There were approximately 130 sessions covering a wide range of topics relating to flash memory or future technologies beyond flash memory.

Understanding the Oracle Data Protection Gap

Post by Colm Keegan (thank you)

For many, snapshots are the go to data protection method for protecting Oracle databases. They can provide efficient, rapid protection from database corruption with high data integrity. But snapshot data protection has its limitations. First, snapshot copies can become corrupted if there is an application corruption issue. Secondly, snapshots will be lost if the storage system fails. And then of course there are retention limitations with maintaining snapshot data on primary storage as most systems only support around 250 snapshot copies. Therefore data has to be copied to another device that is independent of the primary storage device.

Will Phase Change Memory Upstage Flash?

Post by Jim O’Reilly (thank you)

HGST is touting a solid-state drive with a record 3 million IOPS using PCM. The technology looks to be a game changer, but it faces several challenges.

The nonvolatile memory space just got very interesting with the recent demonstration of a super-fast phase change memory (PCM) drive by HGST, a Western Digital company.

Fibre Channel or Ethernet?

There’s been a lot of discussion about the emergence of Ethernet as a storage protocol. Analyst George Crump of Storage Switzerland interviews Scott Shimomura of Brocade about the differences between FC and FCoE with regards to performance, price, and complexity. With 60% to 80% of the market still using FC and with the FCIA announcement of Gen 6, the majority of FC customers have compelling reasons to continue using fibre channel.
