The Hybrid Solution: Best of Both Worlds? Not!
THERE ARE ADVANTAGES AND DISADVANTAGES TO MIXING LEGACY DISK WITH SSD
By Gareth Taube, Vice President Marketing, Kaminario
|
Hybrid is an up and coming enterprise storage architecture, advocated by many legacy storage vendors, that supposedly gives you the best of both worlds: the seasoned storage and reliability architecture of a longstanding enterprise storage leader combined with fast SSD, often from an up and coming SSD startup. One such solution, described in this InfoStor article Gridiron Launches SSD-Accelerated OneAppliance Array, combines NetApp’s E-5400 Series storage array with GridIron’s flash-based TurboCharger Appliance. On its face, this sounds like a great solution, as you get NetApp’s tried and tested high availability, replication, and synchronization features with the fast performance of GridIron’s SSD. However, if you’re considering a solution like this, make sure you ask the right questions.
Is SSD used as a cache or mainstream storage? Many of these solutions, including NetApp’s, use SSD as a cache sitting in front of legacy hard disk storage, not as direct storage. Cache can speed up many applications, but it’s not an ideal solution if you need the absolute highest performance you can get from random, write heavy applications such as online transaction processing (OLTP). First, until the architecture figures out which data to put in the cache you’re going to get slow hard-disk-style I/O performance. Second, with a cache architecture writes are often made directly to hard disk rather than to fast SSD, so write-heavy applications such as OLTP don’t benefit from cache as much as they do from direct SSD storage. Finally, you’re not getting maximum storage efficiency as most of the data in the cache is duplicated on the hard disk.

Series of Posts Highlight Importance of Evaluating Storage Performance in Context with your Applications
MARKS LOOKS AT IOPS, LATENCY, RAID AND OTHER METRICS
By Gareth Taube, Vice President Marketing, Kaminario
|
Network Computing published a three-part series on storage performance written by Howard Marks recently. Each of the posts touched on a different topic related to storage performance. The first installment covered metrics and the second part looked at considering IOPS and latency together. The third one discussed how RAID affects performance including reliability and availability.
I’m pointing this series out because the posts are worth a read if you care about storage performance. They serve as a good reminder that performance is not just about speed and reinforce the notion that evaluating performance in context with your applications is critical. Below I have highlighted the discussion in each of the three articles:

Application Performance Highlights Oracle OpenWorld
SSD CAN MAKE THE DIFFERENCE
By Gareth Taube, Vice President Marketing, Kaminario
|
This year’s Oracle OpenWorld proved both exciting and enlightening as Larry Ellison described Oracle’s cloud vision, including a new multitenant database robust enough for both public and private cloud deployments. There was also a lot of talk about hardware and software working together to achieve superfast DBMS performance, which was why we were happy to demonstrate a Flash-configured Kaminario K2 chugging through a typical database workload at more than 2 million IOPs and 20 GB/s throughput with an ultra-low latency of .98 milliseconds. Since performance and availability go hand in hand, we also demonstrated the K2’s DataProtect self healing and fast snapshot capabilities running an Oracle DBMS. Finally, we took the opportunity to survey more than 400 booth visitors about application performance, flash, and business impacts. The results were striking for the impact SSD can make not only on performance, but on the business.
Here are some of the highlights of our survey:

One Giant Leap Leads to Others
SEMINAL MOMENTS IN SSD EVOLUTION
By Gareth Taube, Vice President Marketing, Kaminario
|
This past weekend, Felix Baumgartner took a giant leap for mankind when he jumped from a balloon — at the edge of space — then proceeded to hurl toward Earth at approximately 800 miles-per-hour landing safely in New Mexico. Aside from Baumgartner’s guts to actually jump (and land safely), one of the most fascinating components of the event was all the technology involved in measuring and monitoring thousands of data points for future analysis. A great deal of the technology was custom built for this task and may lead to other innovations in areas such as video capture and remote monitoring. No doubt it was a seminal moment in aerospace history, but it can also be seen as a seminal moment in IT history as well.
This brings me back to how innovation in data storage has evolved. One of the great things about working in the solid-state drive (SSD) SAN storage market today is that you see firsthand how technologists have developed storage technology so that organizations can use the extra storage power and performance to achieve great business and customer benefits. SSD-powered applications enable companies to be more agile and responsive improving service and benefits to their customers. This means, for example, that environmental and computer network threats can be mitigated faster, investment decisions can be more precise and researchers can detect patterns in TBs of data faster. All because someone took a leap of faith on how this technology could be used.
Giant Leaps in SSD Solutions
As the mass adoption of flash SSD technology in the consumer sector has moved into the data center, we are seeing a lot of innovation first hand as SSD devices get more robust and higher performing. But unique designs in the SSD technology cannot be fully leveraged by older server-based or shared storage array architectures. Recently we have seen traditional storage vendors reach out to the next generation flash SSD devices such as in IBM’s acquisition of Texas Memory Systems and EMC’s grab of XtremIO. But as Randy Kerns point out in his article, Solid State Requires Redesign, these acquisitions are not an easy paring. Kerns warns that “Vendors who continue to sell systems designed for spinning disk will be at a disadvantage in an increasingly flash dominated world. That’s why solid-state technology acquisitions and development will set the stage for the next generation of storage systems.”
This validates the premise on which we built the K2 — high performance storage media requires a high performance storage architecture. And not just any storage architecture, but one that is flexible enough to incorporate new SSD technologies as they evolve, without a redesign to the overall system. This is why we designed the K2’s unique Scale-out Performance Storage Architecture (SPEAR) to readily accept each next generation of SSD media type and continue to deliver reliable and scalable performance. At first, it may have seemed like a big leap in conventional thinking about how to introduce new storage technologies seamlessly into the data center, but so far, our history has shown that with each new jump in the evolution of SSD devices, we, and our customers, have safely landed on our feet.

Kaminario Customer Comments on User Experience
TECHTARGET WRITES ABOUT TESTAMERICA’S K2 SOLUTION
By Gareth Taube, Vice President Marketing, Kaminario
|
Last summer, I posted a blog about Kaminario customer TestAmerica. The company analyzes natural resources such as gas, air and water for contaminants and purity. They deployed a K2 to consolidate about 25 databases to reduce the time required for managers to produce analytical reports.
Nick Mahmood, TestAmerica’s VP of IT, was kind enough to speak with a TechTarget reporter about his user experience. Searchsolidstatestorage published the resulting story on Friday.
According to the article, Mahmood said, “”Being early adopters, you are skeptical about getting into a new product. But we are pretty happy with what we have seen [with the K2].”
Deployment of the K2 has sped TestAmerica’s batch data processing by 50 percent and has improved the time for retrieving customer data by 75 percent.
With the K2 humming along, Mahmood said he is planning the company’s first disaster recovery site and aims to use another K2 to support disaster recovery operations.
Incidentally, Kaminario published a case study that contains additional details about TestAmerica’s K2 implementation.

It’s the Architecture, Stupid
ALL ENTERPRISE SSD SOLUTIONS ARE NOT CREATED EQUAL.
By Gareth Taube, Vice President Marketing, Kaminario
|
If you’re looking for a concise, level headed analysis of the enterprise SSD market checkout Benjamin Woo’s August 31 Neuralytix report entitled Full Spectrum Solid State. It presents a nice breakdown of enterprise SSD solution form factors, dividing the market into:
- PCI expansion boards
- Solid State storage arrays without advanced data management (which he calls SSSD’s)
- Inline storage network cache’s
- Solid State arrays with advanced data management services (which he calls SSSS’s)
- Cache extensions for storage system controllers
- Disk drive packages meant to replace legacy disk drives
The report further divides the market into solutions that are “north” of the storage network (PCI boards and SSD arrays without advanced data management) and those that are “south” of the storage network (the rest) and gives a clear, intelligent evaluation of the pros, cons, and best uses of each.
Kaminario falls into the SSSS category, according to Woo, which he says has the most potential for challenging the hard disk storage systems market head on, especially given the TCO and data center real estate benefits of flash arrays.

COMPUTERWORLD Highlights SSD Users
TheInfoPro Studies SSD Adoption Growth
By Gareth Taube, Vice President Marketing, Kaminario
|
While catching up on some end-of-the-summer reading, one story by Lucas Mearian in Computerworld caught my attention. It highlighted end-user research conducted by TheInfoPro about SSDs and featured three customer case studies.
Survey says —TheInfoPro survey of 255 IT managers and storage admins says that 37 percent of respondents indicated that they plan to deploy SSD technology, up 30 percent from a similar 2011 survey. The same study found that four percent of respondents plan to buy an all-Flash array (in six to 18 months).
It wouldn’t surprise me at all if the percentage of respondents that say they plan to purchase an all-Flash array in a 2013 survey gets a similar boost that the general SSD purchase question received in 2012. Many businesses are still figuring out their transition-to-SSD strategy. If the commitment isn’t there yet to SSD, it seems reasonable that a commitment to a particular type of SSD solution would be less common. A recent SPC-1 benchmark performance report has validated that if a system such as the Kaminario K2 is built from the ground up to maximize SSD performance then you gain in performance, price/performance and sustained performance. As George Crump from Storage-Switzerland concludes from these results:

Welcome to the Data Protection Party
SSD SPOTLIGHT NOT JUST FOR SPEED
By Gareth Taube, Vice President Marketing, Kaminario
|
Aside from enabling SPC-1 benchmark record-breaking speed, Kaminario’s big product focus has been on developing data protection features on its K2 solid-state SAN solutions. Last February, we announced DataProtect that provides users with advanced functionality including high-volume snapshots and non-disruptive operations.
News hit last week that Violin Memory is integrating Symantec’s data management tools with Violin’s memory operating system (vMOS). It is good news for data protection to be in the SSD spotlight. Speed may be sexy but confidence that you won’t lose your data is equally if not more important. SSDs have to be at least as reliable as HDDs for many data center managers to even consider adopting them for their most critical business applications. Read the rest of this entry »

Single-Storage-Vendor Solution or Best of Breed?
BEST OF BREED CAN PLAY WELL WITH OTHERS
By Gareth Taube, Vice President Marketing, Kaminario
|
In a recent blog entitled Pros and Cons of Buying a One-Vendor Storage Solution, Randy Kerns outlines the arguments for and against sticking with one storage vendor. Pro arguments include the simplicity of dealing with a single storage vendor vs. several for troubleshooting and support and the reduced costs that may come from rolling the price of a new technology into a bigger volume purchase. He also argues that single-vendor solutions have the advantage of easy integration. For cons, Kerns simply mentions possible higher cost from a more expensive vendor and the possibility of not getting the best solution. He concludes by predicting that single vendor solutions will predominate, thanks to lower complexity and reduced training and administration costs.

InfoStor Says We’re Hot
KAMINARIO IS WORTH WATCHING
By Gareth Taube, Vice President Marketing, Kaminario
|
This has been an exciting month for Kaminario, thanks to the release of the ground breaking K2 SPC-1 test results (See Kaminario Sits Atop Storage Performance Mountain with Record-Setting SPC-1 Result). However, even before the Storage Performance Council (SPC) announced those impressive results, we learned that InfoStor had named Kaminario one of 6 Storage Startups to Watch. InfoStor put us on the list with five other hot new companies, citing the K2’s architecture–built from the ground up for fast SSD performance–and its ability to provide “tens of GB of throughput and millions of IOPs.” InfoStor also points to the impressive benefits TestAmerica achieved deploying the K2. Thanks, InfoStor and SPC. We like it hot.
