Hardware First – Designing All-Flash Arrays From a Hardware First Perspective

Good post by George Crump (thank you)

Data centers have to meet the increasing performance demands of scale out databases, big data analytics, and dense virtual environments. These data centers need to meet these demands without requiring more data center floor space or consuming more power. All-flash arrays seem to be the “default” answer to today’s storage performance problems. But all of these systems are not created equal. How the all-flash hardware and software are designed, and how these two components work together, will impact short-term results and long-term potential of the flash investment.

DCIG 2015 AFA Buyer’s Guide is Fantastically Horrible

Good post by Brian Beeler (thank you)

Last week DCIG published their “2015-16 All-Flash Array Buyer’s Guide.” We’ve grown accustomed to ignoring most “Magic” and “Best Of” quadrants and awards respectively because almost every time they’re garbage. Analysts or media members anoint some vendor or technology best, shiniest, most rectangle or whatever else they can come up with to promote their own brand. What’s worse are the awards that are paid for, an even more disturbing part of enterprise IT sales and marketing.

Where VSAN doesn’t shine: Sources explain EMC’s ScaleIO purpose

Good post by Chris Mellor (thank you)

EMC introduced its scale-out ScaleIO Node virtual SAN a couple of weeks ago, with hybrid flash-disk and all-flash server chassises. It overlaps as a product with EMC-owned VMware’s VSAN, and therefore EMC’s EVO:RAIL implementation of that, and also competes with scale-out all-flash arrays.

Discussions with sources have clarified EMC’s thinking on the topic, and showed that the overlap is less than originally thought.

Flash, Trash and data-driven infrastructures!

Post by Enrico Signoretti (thank you)

I’ve been talking about two-tier storage infrastructures for a while now. End users are targeting this kind of approach to cope with capacity growth and performance needs. The basic idea is to leverage Flash memory characteristics (All-flash, Hybrid, hyperconvergence) on one side and implement huge storage repositories, where they can safely store all the rest (including pure Trash) at the lowest possible cost, on the other. The latter is lately also referred to as a data lake.

Flash + Object – The Emergence of a Two Tier Enterprise

Post by George Crump (thank you)

For as long as there has been data there has been a quest to consolidate that data onto a single, consolidated storage system, but that quest seems to never be satisfied. The problem is that there are essentially two types of data; active and archive. Active data typically needs fast I/O response time at a reasonable cost. Archive needs to be very cost effective with reasonable response times. Storage systems that try to meet both of these needs in a single system often end up doing neither particularly well. This has led to the purchase of data and/or environment specific storage systems and storage system sprawl.

Pure Storage FlashArray//m

Post by Justin Warren (thank you)

What I like most about the FlashArray//m is the combination of very dull things that combine to make this an interesting piece of infrastructure.

I tweeted out a cheeky picture of a 6509 with a Pure Storage logo on it, because that’s what the FlashArray//m reminds me of: a modular chassis with a backplane that was the workhorse core switch at multiple clients for over a decade. I quite liked them. We’ve had modular chassis like this for years in networking and server gear, so it’s somewhat astounding that storage doesn’t do this, at least, not in the same ubiquitous way (software based things on x86 servers notwithstanding).

Everything you need to know about flash storage performance

Good post by Jim Bahn (thank you)

Due to the unique characteristics of flash, performance validation testing is immensely challenging and critically important; follow these best practices.

All-flash storage arrays (AFAs) are receiving lots of attention these days and for good reason. Compared to spinning disks, AFAs provide dramatically better performance, take up less floor space, and even offer overall cost of ownership advantages. Nevertheless, the cost per gigabyte is still relatively expensive, which means that AFAs should not be deployed for every application workload. The obvious questions are which workloads are most cost-effectively deployed on flash storage and which vendor has the optimal flash storage product for your workloads.

HP Announces A Series Of Innovations To Speed Flash Adoption In The Datacenter

Post by Adam Armstrong (thank you)

Today HP made a series of announcements around its 3PAR StoreServ Storage family. These announcements include lowering the price of flash capacity, new highly scalable all-flash arrays, and flash-optimized data services. These new innovations are aimed at accelerating the adoption off all flash in datacenters.

As we’ve seen over the past few years, flash technology is continuing to be adopted in many areas. With their increased density, performance, and predictability, all-flash arrays will continue to grow, in fact IDC forecasts that flash arrays will see a 46% compound annual growth rate over the next five years. Customers are looking to extend the benefits of flash into the datacenter.

Flurry of new data storage technology can bring confusion

Post by Rich Castagna (thank you)

Confusion reigns in the storage world, as new data storage technology tries to find its place in the data center.

In a blizzard, it’s hard to see a single snowflake. And with the avalanche of new data storage technology that has swirled around data centers the past couple of years, it can be pretty tough to pick out that exemplary piece of engineering innovation and dexterity. They say no two snowflakes are alike (how “they” came to that conclusion, I’ll never know) and, similarly, this data storage maelstrom is marked by a staggering number of new products and product categories. In other words, it’s tough to figure out.

New X-IO ISE 800 All-Flash Array

Good post by Chris Mellor (thank you) over at El Reg

X-IO’s five-year warranty, maintenance-free sealed disk and disk+flash arrays have a new brother: the all-flash ISE. It’s sprinted right to the top of the SPC-1 price/performance benchmark charts.

The ISE 800 comes in a standard 3U X-IO enclosure and uses X-IO’s Gen 3 architecture, which first appeared in the ISE 780 in January. There are three models:

  • 820 – to 6.4TB pre-RAID capacity (2.7TB RAID 10, 4.3TB RAID 5)
  • 850 – to 25.6TB pre-RAID capacity (11.4TB RAID 10, 18.3TB RAID 5)
  • 860 – to 51.2TB pre-RAID capacity (22.9TB RAID 10, 36.6TB RAID 5)

All provide a max of 400,000 IOPS, or 260,000 IOPS with what is called an OLTP workload. There is up to 5GB/sec of bandwidth available.
