Comparison of technology-defined storage solutions: max IOPs, raw capacity, total cost, and cost per GB per IOP.

Original posted at https://www.freeitdata.com/.

Buzzwords suck. That’s right, I said it. Hybrid, All-flash, Converged, Hyper-converged, Data-aware, VM-aware, Software-defined, Object Storage, BigData, Scale-out – we get it, but why is it all so confusing? Or better yet, why is it all so similar?

In Spite of the Buzz - A Win for the Customer

Despite the overuse of buzzwords and re-classifications, the storage industry has actually seen dramatic improvements over the last 3-4 years. All of these changes are great for the customer. More efficient technologies & more competition have lead to lower operating cost, better pricing, and better solutions. But what good is saving all that time and money implementing and using these products, if it takes just as long to weed through all the jargon to find the right one?

Technology-Defined-Storage

There are plenty of options and a ton of overlap, but each of these unique solutions has a place in today’s modern data centers. Let’s take a moment and weed through the buzzwords to get a better understanding of where each one fits best.

  • Performance Centric – The top tier. The absolute must have NOW situations. There are several solutions that will fall into this section. Typically, the all-flash technologies that promise 300k IOPS. These types of solutions are best suited for your production database or VDI environments, but are often limited by budget and capacity.
  • Me Too (Hybrid) – The two trick ponies. These solutions typically combine a flash element with spinning disc to create a “best of both worlds” scenario. You can get speed and capacity at a reduced cost when compared to the performance tier. They also aren’t the cheapest, or the fastest.
  • Designed for the virtually minded – Sliding all my money to the middle of the table betting on “virtualization black”. Very specific and very good at what they do, these solutions focus on how they function within virtualized spaces.
  • Cheap-n-deep (Capacity Play) – Yes, they still have a place in our hearts. The “box of drives” are still very useful inside today’s modern data centers. Perfect for backup/archiving and large amounts of unstructured data. Typically these boxes won’t overwhelm you with performance or features, but they fit the wallet nicely.
  • All-in-one (Converged + Hyper-Converged) – I like Legos too. Like building blocks, these solutions allow you to group compute, storage and networking into one device and stack them as needed. This makes it super simple to manage your environment and allocate assets, but it’s an all or nothing type buy.

Below we have dissected a few of the industries leaders to look at IOPS, Capacity, cost and how they compare. This is a great snapshot, but doesn’t by any means tell the entire story.

Software Makes All the Difference

It’s all in the software. Obviously, reliant to some extent upon the hardware, the software really determines how the important stuff is handled...the data. De-dupe, compression, hot data, cold data, these features all play a big role in the IOPS and capacity capabilities of each solution. Not to mention the reporting and administration capabilities provided by these unique and elegant software platforms. Many of the hardware components inside each of these “boxes” are virtually the same. They are manufactured by the same companies, assembled in the same manner, with same CPUs, the same RAM. The software layered on top of this hardware really defines its capabilities.

Fit-Defined-Storage

In a perfect world, we just look at the speeds and feeds, features and functionalities and find the best technology to fix the problem, but there are many other business considerations when evaluating data center technologies. Installation, integration, usability, performance, the list goes on and on, but budget is often the biggest one.

Uh oh. More buzzwords - TCO, cost per GB, cost per IOP. All just ways to assess whether those features are worth the money. We couldn't just look at cost as a single determinant on picking the right solution, but looking at it relative to the performance and capacity is one easy way to determine “value.” Here is a look at the same data above by cost per GB.

How about looking at it by cost per GB, per IOP.

One size doesn’t fit all. At least not when you factor in more than just size. The process of evaluating solutions can become long, complex, and costly.

Scale-out, IOPS, TCO, cost per GB…all of these things together with budget, timing, integration & ease of use factor into finding the right fit. By themselves they’re just features, much like buzzwords.

It currently doesn't support NAS storage (CIFS and NFS), but the dashboard provides everything needed in a single view.

What is most valuable?

The dashboard of the product provides a lot of value to the administrator. It provides everything needed in a single view.

How has it helped my organization?

The product improved the organization functions by increasing system response time and productivity. Before the product was installed, applications ran poorly, and slow, which affected the productivity of the workforce. Once the product was in use, the applications ran quickly, and the workforce did not encounter any bottlenecks and became more productive.

What needs improvement?

The product could improve by providing the capability to support NAS storage – CIFS and NFS. Currently, the product only supports block storage (SAN).

For how long have I used the solution?

The solution has been in place for three years.

What do I think about the stability of the solution?

There weren’t any issues encountered other than firmware upgrades that needed to take place.

What do I think about the scalability of the solution?

The capacity we needed did not cause any issues with scalability. However, fairly large companies may have issues expanding. The controllers are limited to a certain amount of storage. When that capacity limit is reached on what the controllers can handle, another set of controllers will be needed to compensate for the additional storage.

How are customer service and technical support?

Customer Service:

Their support and customer service is excellent. They monitored our storage arrays and knew about issues we had when they were reported. They assisted and made themselves available for some work where help was needed.

Technical Support:

I would rate their level of support an 8/10. Only because issues require escalation during off hours, but they do respond when issues are escalated.

Which solution did I use previously and why did I switch?

The technology the company had were from two competing vendors, but none had flash storage. This was the first time the company ever used flash storage.

How was the initial setup?

The deployment was very quick. It is one of the easiest storage equipment to implement.

The initial setup was very simple. The storage array comes very compact with minimum amount of hardware so it’s not bulky equipment which gets delivered in pallets. The setup instructions are extremely easy.

What about the implementation team?

The product was installed by the vendor’s SE. Their level of expertise was a solid 10/10.

What was our ROI?

There was a case study on the product. The work performed by four people is now capable of being performed by one person because of the applications running faster.

What's my experience with pricing, setup cost, and licensing?

All the software is included in the hardware at no additional cost , unlike some of the other storage vendors who charge for certain features such as encryption, replication, etc.

Which other solutions did I evaluate?

We looked at the other offerings from existing vendors but we took advantage of the free POC and also the special introductory rate.

What other advice do I have?

Based on my experience with the product, I would recommend it. I have never experienced an outage with the product or had any support that was below excellent. But there are other products in the market which compete well, however, I do not have any experience with the other products’ pricings and support.

Very good product but it needs more effective de-duplication techniques

What is most valuable?

Flash Reduce - The data reduction methods employed by the Pure Storage array is one of the best that I have seen.

How has it helped my organization?

The Flash Reduce feature makes use of data de-duplication techniques which in turn reduces the amount of storage required thus reducing the need to procure additional storage.

What needs improvement?

With the introduction of Albireo technology and 81x data de-duplication reduction, Pure Storage better start looking at more effective de-duplication techniques.

For how long have I used the solution?

I used the Pure Storage All Flash Array over an eight month period.

What was my experience with deployment of the solution?

None whatsoever. The implementation partner was very efficient and knowledgeable.

What do I think about the stability of the solution?

An initial issue was encountered which had no business impact and was resolved after a firmware upgrade.

What do I think about the scalability of the solution?

None whatsoever. The product functions as designed.

How are customer service and technical support?

Customer Service:

The business partner performing the support/customer service is very knowledgeable and they even perform weekly visits to determine if all is well.

Technical Support:

Technical support is very helpful and the relevant Subject Matter Experts (SMEs) are readily available globally.

Which solution did I use previously and why did I switch?

Yes, the cost of the previous product (fibre channel array) versus the cost of an all flash array differs drastically. We were pleasantly surprised that we received fibre channel pricing for an all flash array.

How was the initial setup?

The array setup was very simple. In fact it was one of the simplest implementations I have ever experienced. The installation interface is self-explanatory, even a novice could perform the install.

What about the implementation team?

A vendor team performed the installation with the assistance of an in-house team. The vendor team performed the installation very professionally and have a wealth of knowledge across various vendor platforms.

Which other solutions did I evaluate?

Yes, we also looked at EMC, VMAX, and Oracle FS1.

What other advice do I have?

This is a very good product at a very good price, with very good support.

Pure Storage vs. XtremIO

Doing It Again: How Would I POC XtremIO and Pure?

We began our hands-on exploration of all-flash arrays in September 2013, and for all intents and purposes, the testing has never really concluded. If I knew then what I know now, I would have conducted a number of tests quickly during the official “Proof of Concept” (POC) phases.

All of the below tests are worth doing on the named products, as well as other similar products that official support the actions. Some tests particularly target a product architecture. Where applicable, I’ll note that. As with any storage array, the best and first test should be running real data (day-to-day workloads) atop it. The points build upon that being implied.

1. Capacity: Fill It Up!

This test is most practically focused on Pure Storage and its history and architecture. At the same time, the concept is worth processing with XtremIO.

In 2013 and before, Pure’s array dashboard showed a capacity bar graph that extended from 0% to 100%. At 80%, the array gave a warning that space was low, but failed to indicate the significance of this threshold. The code releases up to that point put an immediate write throttle on processing when the array passed that threshold. In short, everything but reads ground to a halt. This philosophy of what percentage truly is full was reassessed and redefined around the turn of the year to better protect the array and the user experience.

Pure’s architecture still needs a space buffer for its garbage collection (GC), which I believe is guarded by the redefinition of “full”. However, I have heard of at least one user experience where running near full caused performance issues due to GC running out of space (even with the protected buffer). If you’re testing Pure, definitely fill it up with a mix of data (especially non-dedupe friendly data) to see how it goes in the 80’s and 90’s.

For XtremIO, it’s a conceptual consideration. I haven’t filled up our array, but it doesn’t do anything that requires unprotected buffer space, so the risk isn’t particularly notable (feel free to still try!). The thing here is to think about what comes next when it does get full. The product road map is supposed to support hot-expansion, but today it requires swinging data between bricks (i.e. copy from an array of 1 x-brick to 2 x-bricks, 2 x-bricks to 4 x-bricks, etc).

2. Diversify & Observe: Block Sizes

Pure and XtremIO use different block sizes for deduplication and process those block sizes differently as well. Services and applications similarly use different block sizes when writing down to arrays. Microsoft Exchange favors 32KB blocks, while SQL Server tends toward 64KB blocks. Down the line, backup applications and jobs often times use blocks ranging from 256KB to 512KB. OS and miscellaneous writes stay on the smaller end around 4KB (or less).

Since Pure takes a bigger block size and then looks for duplicate patterns of various lengths, larger blocks like backup jobs have the potential to raise latency. It’s simple physics as I mentioned in the previous post–finding matching cards in 100 decks takes longer than finding them in 2 decks (take the analogy for what its worth). Your environment may not create any issues for a Pure array, and Pure arrays, code, and hardware may have moved beyond that by now, but test and verify.

XtremIO uses a fixed block size so bigger blocks don’t affect how its deduplication processes data. Everything is chopped down to 4KB (pre-3.0) or 8KB (3.0+) blocks. The thing to observe here is how deduplication and compression works. With the same data on both arrays (Pure & XtremIO), which provides the better data reduction? What are the trade-offs, if any, for that advantage?

3. Patch & Reboot: High Availability

My experiences with array software updates have almost always involved the words “non-disruptive”. In fact, since 2006 and our first EMC CLARiiON CX300, I can’t recall an update that required downtime. Sure, they recommended it and things were slower during updates, due to write-cache disabling, but one storage controller/processor was always online and serving data. Furthermore, in the storage array realm, “high availability” is pretty much a given. As the saying goes, though, “trust but verify”.

When you get your POC arrays, I’d recommend making sure that you can go through a software update during your evaluation. If the vendor doesn’t have one releasing during your POC, ask to have the POC unit loaded with the previous, minor revision of the code/software. Then, with your data fully loaded on it, schedule a time to perform that Non-Disruptive Update (NDU). This also provides the benefit of testing out the technical support experience with Pure and EMC Support (or any vendor).

Pure probably has an equivalent to this command, but you can also perform additional fail-over testing of XtremIO arrays by logging into the XMS CLI and running the following commands to see how an HA event is handled:

  • Open two SSH sessions to the XMS
  • In one session, run the following command. It repeats every 15 seconds. Open the XMS GUI to see more real-time data at the array level.
    show-targets-performance frequency=15
  • Observe/verify that traffic is flowing down all initiators evenly
  • In the second session, run the following command. Note that this will take a controller out of service (and may affect performance or availability).
    deactivate-storage-controller sc-id=2
  • Watch the first SSH session and the GUI for the effects of the fail over (recommend waiting five minutes at least before re-activating)
  • In the second session, run the following command to reactivate the controller:
    activate-storage-controller sc-id=2
  • Observe/verify that traffic returns to an even flow across all initiators

If real-world data on your array doesn’t generate at least 10,000 to 20,000 IOPS, I recommend running IOmeter on a few array-connected servers to create additional load. Four VMs/servers running IOmeter with the following characteristics provided roughly 34,o00 IOPS in my experiments.

  • Fully random I/O
  • Two disks checked per VM (in different datastores; mostly just to see how IOPS patterns affected different volumes)
  • Four outstanding IOPS
  • Access Specification on VM 1: All-In-One
  • Access Specification on VM 2: All-In-One
  • Access Specification on VM 3: 4K / 25% Read (OS simulation, heavy writes)
  • Access Specification on VM 4: 64K / 50% Read (SQL simulation)

4. Other Stuff: It Depends

This last part entirely depends on your environment and how you intend to use a new all-flash array. If you are fully virtualized like we are, look at the best practices, recommendations, and supported features. Compare your backup solution and architecture with array support. Do you need things like transportable snapshots for Veeam Backup & Replication, for example? If you use snapshots, how do you create, export, and delete them? Make sure any APIs that you use (or want to use) are supported.

At the end of the day, every environment and every use case is different. Relationships also matter, so your account team and VAR may sway your feelings toward, or away from, a given product. If all of the above tests go smoothly, smaller things like the UI and implementation process may make or break it. Or if you find the chinks in both products’ armor, support may be winning vote.

Either way, near the end of your evaluation, take some time to step back and write down the results and the pro’s/con’s to both or all of the products tested. Chances are you’ll find what matters to your organization on the page when you do.

I can't speak to the specific POC mentioned above or in the prior comments and why the parameters were set the way they were, but I have been part of several POCs and our recommendation is to ALWYAS use IDC's recommended parameters for testing an All Flash Array, which include filling the array up entirely and then wiping not once, not twice, but three times.

A valuable feature is the data reduction capabilities but scalability could be improved

What is most valuable?

The features of this product that are most valuable include the data reduction capabilities. Being able to write and read data at incredibly high rates of speed and reduce the footprint of your data by three to four times at least is invaluable. Also the ability to clone and snapshot the data with little to no additional size impact. In the database world this function has quickly become a must have and not just a nice option.

How has it helped my organization?

The organization in which the product is deployed had many instances of the cache databases. There were instances in production, backup, test, development and others. There were then copies of copies. There were updates to databases and refreshes, as well as exports for reporting. There were more than 20 instances of the same data that existed in production. The space reduction and cloning capabilities alone resulted in major cost and administrative overhead reductions across the board. That doesn’t even account for the ability to reduce RPO/RTO to very low expected time frames.

What needs improvement?

The overall scalability for this product could be improved as well as having a single console to management multiple arrays. The scale is constantly being addressed as SSD drives get larger so will the overall capabilities of the arrays.

For how long have I used the solution?

I have used this solution for less than a year from POC to production deployment. [Pure Storage FA-420 and (2)FA450 array.]

What was my experience with deployment of the solution?

There were no issues during the initial deployment of the array.

What do I think about the stability of the solution?

There have been no issues at all with stability. The only issue was on our side, procedurally - how we did our zoning needed to be modified. Instead of zoning in groups of hosts we needed to do individual zones for each host to the arrays separately. This had nothing to do with the array though.

What do I think about the scalability of the solution?

There have been no issues at this point. There has not been a need to scale yet, however the scale prior to deployment was more than sufficient.

How are customer service and technical support?

Customer Service:

Customer service has been outstanding. During the HA testing in the POC period we had people contacting us to verify that status of the array before we had completed the testing phase. They are thorough and capable.

Technical Support:

Implementation was flawless and any remote support they handled any questions we had with ease. There really haven’t been issues of any nature that required much technical savvy though.

Which solution did I use previously and why did I switch?

We had not previously used an all flash array. We POC’d the next best competitor, but feature wise, overall system stability and space reduction numbers made it so that Pure was the clear leader.

How was the initial setup?

It took about an hour to get multiple arrays installed and deployed. They were incredibly easy to setup and even easier to get online and provision storage.

What about the implementation team?

We implemented through a vendor, but the manufacturer did the actual installation. There were no PS hours incurred for the installation from the vendor.

Which other solutions did I evaluate?

We evaluated through technology research: Whiptail, SolidFire, XtremIO and Pure Storage. Ultimately we POC’d XtremIO and Pure Storage.

What other advice do I have?

Definitely take the time to perform a POC. There are multiple players in this market right now that have good offerings and specific environments are very different. Also, don’t get sucked into the IO race. At the end of the day, the number of thousands of IO didn’t really have that much impact on our product, because minimum IO reqs were far below anything, any of the arrays advertise and produce. Also, just because an array can do a million IOPs doesn’t mean it is the right fit for your environment.

This storage has to be the most well thought out and effective storage that I have had the privilege to work with.
