What Kind of SSD Solution is Best for your Needs?

STORAGE SWITZERLAND POST SUGGESTS QUESTIONS TO ASK

Judging from industry chatter and published articles, it is clear that the debate about all SSD versus a hybrid SSD/HDD array is picking up.  Our blog touched on this a little bit recently.  This strikes me as a good thing. While we believe the industry is on a journey to the time when HDDs will be used like tape is today, naturally there are waypoints.  People need to balance their storage needs and budget with all available options to them.

This brings me to an article I recently saw from Storage Switzerland titled Flash SSD May be the Answer, but It Raises Many Questions.  It highlights some of the questions storage managers should start asking their vendors about SSD storage to arrive at the best type of SSD solution for their needs.

The story suggests questions about sharing capabilities, high availability and a few other topics that organizations should ask vendors.  When we speak with customers, we try to ask questions of our own.  So here are three questions we always ask customers considering a hybrid or all-SSD solution:

Application Performance Highlights Oracle OpenWorld

SSD CAN MAKE THE DIFFERENCE

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:

TestAmerica Combines Kaminario & Dell Compellent for Faster Batch Processing & Data Replication

COOPERATION BETWEEN SSD AND HDD VENDORS PRODUCED A MORE EFFICIENT DATA CENTER OPERATION

The Leader in Environmental Testing — TestAmerica Inc. is a key player in ensuring that the environments surrounding our houses, cities and towns are safe. The Colorado-based company helps clients monitor and analyze the quality of natural resources such as air, gas, soil and water.

To support its approximately 40 labs and 3,000 employees across the United States, it has developed TALS, an information management system for sharing and processing data. Speed is an essential component of TALS because the company must be able to deliver customer reports very quickly because of the environmental impacts test results can have.

A new 10TB K2 is now part of the TALS system within a centralized data center delivering at least 300K IOPS and storing approximately 7TB of data. Prior to TALS, TestAmerica used a collection of 25 SQL Server databases that caused synchronization problems and delays in batch processing. They are enjoying great performance results now including a 50 percent improvement in batch processing time and a 75 percent improvement in customer data retrieval time. You can read the case study or the press release.

Free Buffer Wait

So far in the series of Oracle storage wait events we have covered several common events such as “db file sequential read”, “db file scattered read” wait events, direct path read and Direct path Read/Write temp. In this post, I will describe another wait event that in many cases is caused by weak storage performance.

Get the Most I/O Performance from Your SAP Oracle Applications

NEW ACCELERATING SAP PERFORMANCE AND SCALABILITY WHITEPAPER AVAILABLE NOW

By Gareth Taube, Vice President Marketing, Kaminario
Bookmark/FavoritesFacebookDeliciousDiggGoogle+LinkedInTechnorati FavoritesStumbleUponTumblrTwitterShare

We frequently speak with organizations that are considering consolidating their database applications to improve system management and flexibility as well as reduce costs.  One popular area where consolidation is a hot topic is ERP applications.  In a recent post, we talked about how the Israel Electric Company improved their SAP transaction speed by up to 25 times by using the Kaminario K2 all solid-state SAN storage solution. What this company and others like it found is that even if you put a lot of computing horsepower into your servers and databases, your application performance can suffer if your storage system can’t keep up.  And, simply adding more disks doesn’t solve the problem.  Read the rest of this entry »

Sometimes There’s No Other Way

TWO COMPANIES THAT SOLVED THEIR PERFORMANCE ISSUES WITH SSD.

By Gareth Taube, Vice President Marketing, Kaminario
Bookmark/FavoritesFacebookDeliciousDiggGoogle+LinkedInTechnorati FavoritesStumbleUponTumblrTwitterShare

SSD is often talked about as a performance solution for online transaction processing, high performance computing, and applications where cost per IOP is sometimes more important than cost per GB. However, SSD is about much more than that. There are times when there’s simply no other reasonable way to solve an I/O performance problem. There are two case studies on the Kaminario site you should check out if you want to know the breadth of what SSD can accomplish, particularly when you have the freedom of choice theK2 provides.

The first case study is about the Israel Electric Company (IEC), which provides electricity for more than 2.5 million Israelis in all sectors of the economy. The IEC has been replacing a hodge podge of different IT systems with a single SAP ERP solution. Shortly after the first round of ERP modules went live, users started complaining of performance issues with lots of transactions, queries, and reports, despite IEC’s use of some of the most powerful servers, disk storage systems, and databases on the market. A thorough analysis revealed I/O performance as main culprit, which brought the IEC to Kaminario and a K2 filled with DRAM. The result was an improvement in transaction speed by up to 25 times–10 times on average–and latency by up to 7 times, even during resource intensive operations that would formerly slow things down to a crawl. Imagine the productivity improvements.

“db file sequential read” wait event

By Eyal Markovich
Bookmark/FavoritesFacebookDeliciousDiggGoogle+LinkedInTechnorati FavoritesStumbleUponTumblrTwitterShare

In a previous post, I have discussed steps and methods to calculate I/O wait from an Oracle AWR report. The key and sometimes challenge task is to identify wait events which are related to the storage. While many waits may be caused by I/O related performance issues, the following waits are the main ones on which Oracle foreground session will be waiting:

  • db file sequential read
  • db file scattered read
  • direct path read
  • direct path read temp
  • direct path write temp
  • free buffer wait
  • log file sync
  • read by other session

In the next few posts, I will explain these waits. This important information is taken from the Oracle performance white paper written by Bartal Vindzberg (availability of this white paper will be posted in a future blog article).  Read the rest of this entry »

Ain’t it Hot, Hot, Hot

SSD IS HOT, BUT DO YOUR HOMEWORK SO YOU DON’T GET BURNED.

By Gareth Taube, Vice President Marketing, Kaminario

There’s been a lot of buzz in the SSD market in the past few months, including a public offering, multiple instances of major new funding, and commitments to SSD from the big storage vendors. Fusion-io, maker of Flash memory PCIe server cards, completed its initial public offering on June 9, closing at $22.50 a share and raising $237 million. Kaminario closed a $15 million series C funding round. Violin Memory, maker of flash memory arrays and caching systems, closed a $40 million Series C funding round shortly after raising $35 million in February. Pure Storage raised $28 million in venture capital even though its solution is still in private beta testing and has yet to be revealed. EMC has made a commitment to boosting several of its arrays with flash and of course Oracle bases its Exadata appliance on Flash. Anyone how knows anything about this market is probably already weary of hearing the phrase, “Flash is the new disk and disk is the new tape.”
