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.

VMware’s high-wire balancing act: EVO might drag us ALL down

7845f-iwillsurvivethis

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

In the battle for the software-defined data centre, one of VMware’s challenges is how to deliver software-defined/controlled storage without screwing up parent EMC’s hardware-based storage revenues.

VMware is an overall EMC Federation member along with Pivotal and the EMC Information Infrastructure (EMC II) unit. The three are allowed to compete, but what will EMC’s chairman and overall CEO Joe Tucci say if one federation member screws up another’s revenues and strategy?

VMware Announces Software Defined Infrastructure with EVO:RAIL

Good Post by Chris Wahl (thank you)

Wow, the world of converged infrastructure sure is on fire. It seems that everyone is looking to stuff all of the data center food groups into an appliance-like node for simpler data center architecture models. Further validating this idea, VMware has entered the ring with their hyper-converged infrastructure offering called EVO (check out the landing page, here).For a moment, however, let’s take a step back and look at the various tiers of convergence that are available to data center customers today:

OmniStack Inside of Cisco? Yes You Can!

Post by Brian Knudtson (thank you)

For my first official post for SimpliVity, I have the distinct privilege of announcing the technical details of our new offering: OmniStack Integrated Solution with the Cisco UCS C240. With this announcement, you can easily purchase both Cisco’s C240 M3 server and SimpliVity’s OmniStack technology and have them factory integrated and configured. That’s right! You can now purchase SimpliVity’s ground-breaking technology in a Cisco-based appliance.

VMworld 2014 – EVO:RAIL and EMC’s approach

Good Post by Chad Sakac (thank you)

Before I go much farther in talking about EVO:RAIL, I want to quickly make a black and white statement – based on what I expect analysts/press misunderstanding today’s announcements (we’ll see if they do this):  VMware is NOT getting into the hardware business :-)

Looking at the PR, and even the way EVO:RAIL is positioned as a “product” (to me, it is a OEM program, and a VMware software product –  EVO:RAIL manager – that helps OEMs build hyper-converged appliance products) I can see why people may be confused.  Let me try to make this clear:

Let’s pop the hood on an HP StoreEver LTO-6 Tape Drive

Post by Mark Fleischhauer (thank you)

Whether it’s a classic car, a racecar or your everyday passenger vehicle, you always want to know what’s under the hood. You want to know its top speed, its fuel economy, or perhaps information about its advanced safety features. Just like our new modern cars, the HP StoreEver LTO tape drive has continued to make technological advancements with greater speed, better efficiency, more capacity, and advanced features to address growing user demands with big data that needs agility, performance and capacity.

Performance expectations with ISL compression

Good post by Erwin van Londen (thank you)

So this week I had an interesting case. As you know the Hitachi arrays have a replication functionality called HUR (Hitachi Universal Replicator) which is an advanced a-synchronous replication solution offered for Mainframe and OpenSystems environments. HUR does not use a primary to secondary push method but rather the target system is issuing reads to the primary array after which this one sends the required data. This optimizes the traffic pattern by using batches of data. From a connectivity perspective you will mostly see full 2K FC frames which means on long distance connections (30KM to 100KM) you can very effectively keep a fairly low number of buffer-credits on both sides whilst still maintain optimum link utilization.

Despite being declared dead, Fibre Channel continues to evolve with FC-BB-6

Good post by Greg Schulz (thank you)

Like many technologies that have been around for more than a decade or two, they often get declared dead when something new appears and Fibre Channel (FC) for networking with your servers and storage falls into that category. It seems like just yesterday when iSCSI was appearing on the storage networking scene in the early 2000s that FC was declared dead yet it remains and continues to evolve including moving over Ethernet with FC over Ethernet (FCoE).

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.
