Making All-Flash 3D TLC SSD Arrays Enterprise Ready

3d-nano-ssd-rcm992x0

Good post by George Crump (thank you)

All-Flash Array Vendors are now releasing systems with 3D TLC SSDs. They claim that they have reached price parity, without data efficiency, to mainstream data center hard disk arrays. 3D TLC NAND does bring the price per GB of flash storage down considerably, but it does carry the risk of device failure and data loss. Understanding how a vendor mitigates that risk is critical to vendor selection.

Is Deduplication Useless on Archive Data?

52425-338038_4786

Good post by George Crump (thank you)

One of the techniques that storage vendors use to reduce the cost of hard disk-based storage is deduplication. Deduplication is the elimination of redundant data across files. The technology is ideal for backup, since so much of a current copy of data is similar to the prior copy. The few extra seconds required to identify redundant data is worth the savings in disk capacity. Deduplication for primary storage is popular for all-flash arrays. While the level of redundancy is not as great, the premium price of flash makes any capacity savings important. In addition, given the excess performance of AFAs the deduplication feature can often be added without a noticeable performance impact. There is one process though where deduplication provides little value; archive. IT professionals need to measure costs differently when considering a storage destination for archive.

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.

Why i think VSAN is so desruptive

Post by Chuck Hollis (thank you)

Looking for a great disruption story in enterprise IT tech?  I think what VSAN is doing to the established storage industry deserves to be a strong candidate.

I’ve seen disruptions — small and large — come and go.  If you’re into IT infrastructure, this is one worth watching.

A few years ago, I moved from EMC to VMware on the power of that prediction.  So far, it’s played out pretty much as I had hoped it would.  There’s now clearly a new dynamic in the ~$35B storage industry, and VMware’s Virtual SAN is very emblematic of the changes that are now afoot.

What you won’t see in 2015

Good post by Enrico Signoretti (thank you)

After all the predictions I read about 2015 (…and many of them are pretty ridiculous indeed) I can’t help but make mine, which I would like to approach in a totally different manner, using common sense first and trying to make an anti-prediction for enterprise IT in 2015. So here is my opinion on what you won’t be seeing this year in your Datacenter.

One new tape innovation, one giant leap in storage technology

Post by Jack Arnold (thank you)

I reside at about 39 degrees north latitude in the United States, which means that it is fall here. I live in the middle of a mostly deciduous forest, so right now fall is at its peak. The only word that can be used to describe the scenery of yellows and reds is “spectacular.” I’m including a picture of a bush outside my house. I could put up a full portfolio, but since the intent of this post is technical rather than artistic, we’ll save that for another time and place.

The End of a Necessary Evil: Collapsing the Memory Hierarchy

Good Post by Martin Fink (thank you)

Four hours and 31 minutes.  That’s how much longer my HP Folio 1040 laptop estimates I can work given the energy stored in its battery.  Where does all that energy go? My CPU meter shows only slight activity. I’m only running a couple of apps and I’m not typing thatfast.

It turns out that today’s computers spend most of their time and energy shuffling data between tiers of storage and memory. In modern systems, this hierarchy can be more than 10 layers deep. In geek land, we call this “the volatility chain.” We’re all so used to this that few of us ever think to question it. But on the face of it, this is an odd way to go about computing. Why not hold all your data in main memory, all of the time?

Low expectations yield disappointing technology ideas

Good Post by Jon Toigo (thank you)

Warmed-over or half-baked technology ideas might produce profits for the vendors that manufacture them, but they won’t solve storage puzzles.

Maybe it’s a sign of the times: the earnings reports of leading storage array vendors are in the tank, product announcements tend to be humdrum “incremental releases,” and unemployed smart guys are contacting me to ask if I know of any job opportunities. Makes you wonder if the Great Recession is really over.

X-IO makes hardware-defined storage exciting

Post by Lauren Malhoit (thank you)

X-IO deals with disks within its systems in two impressive ways. Lauren Malhoit says these approaches make X-IO stand out from other storage vendors.

I attended Storage Field Day 5 (SFD) a couple of weeks ago; SFD is a part of the Tech Field Day. Before the actual SFD event, we attended a Software-Defined Data Center (SDDC) Symposium. SDDC is a new, sexy buzzword in tech.
