Why Does An All-Flash Array Architecture Matter More Than Ever?

Posted by Tim Stoakes on Jan 20, 2015 5:03:29 PM

The beginning of a new year is often an opportunity to reflect and make resolutions. In storage, you may be part of a growing group of customers that has made the resolution to stop investing in disk, and make the move to flash. In this blog series, I will share with you why not all enterprise flash storage is made the same; and that architecture matters.

Introducing the “Architecture Matters” Blog Series

Posted by Tim Stoakes on Jan 19, 2015 5:01:05 PM

Inarguably, it has never been a better time to be a storage user deciding on a next-generation all-flash array. The last 18 months have been a phenomenal time for the storage industry, with a flurry of all-flash array product announcements, each claiming unique approaches to solving the challenges of getting rid of disk and going all-flash.

Cloud Computing

Posted by VIOLIN SYSTEMS on Jan 5, 2015 9:00:45 AM

Run a simple search. “What is Cloud Computing?”

It will yield thousands of whitepapers, blogs and videos, some a few short words, some that run to great length. All of them saying essentially the same thing: cloud computing is there when you need it and not there when you don’t.

Imagine that you are in a meeting on a new business iniative. Tremendous new data sets will be generated and required service levels will be high. You send a text to your leading cloud storage provider requesting 30 Terabytes of additional storage with the maximum available data protections applied, and it must be available ASAP… “Done” the reply text a few seconds later.

CIO Predictions 2015

Posted by VIOLIN SYSTEMS on Dec 23, 2014 12:05:20 PM

With smartphones now carrying more power than the original PC’s and laptops, IT has become a commodity to many C-level execs similar to chairs, machinery, or any other item used to run a company. CIO’s are now constantly challenged by other C-level execs – CEO's, CFO's, and Line-of-business owners – on what IT is doing to “impact the business.”

Violin Systems and OpenStack Momentum

Posted by VIOLIN SYSTEMS on Nov 20, 2014 3:21:55 PM

Much of the technology world descended on Paris recently as the OpenStack Summit held its semi-annual get-together for a meeting of the minds.  It was my good fortune to attend with colleagues from Violin Systems. We even managed to see a few local sights while we were there!

Latency Matters

Posted by VIOLIN SYSTEMS on Jan 24, 2014 1:41:06 PM

Independent studies by Google and Microsoft’s Bing team were seeking to understand the impact of latency on user behavior. Their studies generated surprising results. The companies presented their results jointly at the O’Reilly Velocity conference in San Jose CA in May of 2009.

They wanted to assure their investment in systems to deliver search results and advertising was indeed based on user results, and if possible, business impact. The fact that these two companies came to very similar conclusions after their independent experiments brings a lot of credibility to their joint conclusion. The result of their research: latency matters.

The Advantages of Inline Deduplication?

Posted by VIOLIN SYSTEMS on Dec 14, 2013 9:30:16 AM

Many vendors make some very interesting claims about their inline deduplication feature and why it is superior to post-processed deduplication.

Their claims:

  • Save you space
  • Increase the endurance of the flash by eliminating writes
  • Increase the performance by not sending writes to their SSDs

The purpose of this blog is not to  weigh in on which inline or post-processed dedupe is “better” but to make clear that the supposed advantages of inline dedupe, improved endurance and increased performance, DO NOT EXIST! 

How can this be? The key point to understand is that BLOCK STORAGE deduplication ratio and the WRITE ELIMINATION ratio due to deduplication have nothing whatsoever to do with each other.

Garbage Collection & XtremIO – Fiction & Fiction: Part III

Posted by VIOLIN SYSTEMS on Dec 10, 2013 3:56:05 PM

Part II of this series on the XtremIO product launch triggered some questions, which I will address in this post.

  • Is the performance of XtremIO “consistent” AND “predictable”?
  • Is it even “consistent” OR “predictable”? 
  • Is it “the only all-flash array that requires no system-level garbage collection yet maintains consistent and predictable performance.”?
  • Does it provide “the industry’s most consistent performance”?
  • Does it never happen that “IOPS suddenly drop and latency suddenly increases”?
  • Is their mixed R/W performance “stable”?

Let’s check the XtremIO Spec Sheet for the 2 brick system they were using in their demos during their product launch.

Garbage Collection & XtremIO – Fiction & Fiction: Part II

Posted by VIOLIN SYSTEMS on Dec 9, 2013 2:12:46 PM

In Part I of this series, I told you to take note of this slide and that we would revisit it to show just how misleading the XtremIO launch really was.

Now, before I get into what this says about XtremIO, let me first explore what it does not say about “Startup,” who, from context, appears to be Pure Storage. Pure Storage is my competitor and I am not going to tell you I think their product is even remotely as good as ours (I’m sure they would say the same thing), but that doesn't mean that I will let EMC make itself look better than Pure when I would argue that it is the other way around.

Let’s examine the numbers EMC presents and separate fact from fiction.
