When Big Data Hurts

by Robin Izsak 5. December 2013 03:38

I recently spoke with Bell Mobility's Adam Moore, a member of the organization's OSS Systems Integration Team. Bell Mobility is Bell Canada's wireless division, employing a multitude of analysts who eat, sleep, and breathe Big Data. They capture metrics and run analytics on call failures, call drops, and call volume—helping the company provide better service to their customers.

Sure we hear a lot about Big Data these days, but we need these catch phrases to talk about abstract concepts. And Big Data is as important as it is abstract: it represents a smarter way to do business, to create value from all this data we have, and to make better decisions. Big Data enables Bell Mobility directors to pinpoint inefficiencies and see where optimization is needed to maintain optimal services to a broad customer base.

So on our call, Adam told me that things had slowed down. His users were dealing with longer and longer SQL query times, which was impacting their ability to do their jobs. Faced with significant data growth and a need for faster delivery of that data to meet SLAs with their users, Adam's team needed a solution to escalating performance problems, like right now. 

In assessing their options, Adam and team conducted an evaluation of V-locity® VM™. The results? A 61% reduction in I/O to the SAN, which led to 98% faster data processing times. And backups? "They used to run at 10MB per minute and sometimes didn't complete at all. Now they run at 60-120MB per minute and complete consistently."

The Notorious 45-Second Query

by Robin Izsak 19. November 2013 05:17

You just clicked OK. Now wait 45 seconds for your query to complete. Now do this a bunch more times until you've compiled all the data you need for a report. And right about now, frustrated, you think about getting a snack and more coffee. 

That's what was happening at SunCoke Energy, as sys admin Chris Mueller's business users started complaining of painfully slow queries and application response.

When the "45-second query" became notorious around the office, Chris and his team started a months' long troubleshooting mission, trying to tune Oracle performance and improve the speed of the business's Cognos VMs. “A bad day for my team is when our people can’t do their jobs—it’s like trying to find a needle-in-a-haystack, troubleshooting for performance.”

After a number of attempts, including consolidating all the VMs and updgrading the SAN, the team brought in V-locity® VM™ and dramatically improved speed—overnight.

For and By

Diskeeper has long been a popular compliment for design and engineering software systems, including by the the most popular design and enginerring software company itself:

“Diskeeper indeed provided the ROI we expected. We are very satisfied. I have been using your product on my personal desktop and at work for the past few versions. It always proved to be a valuable product for transparent defrag and overall performance. 

Prior to installing Diskeeper our systems were almost unresponsive. This easy deployment was done right away as Diskeeper was much needed. It is a fine product that we rely upon.  It was reported to me that the automatic defrag did not take any visible resources or produce any slower performance which was really appreciated. 

The automatic defrag also helped overall performance greatly on the files sytem access. One of the folders has millions of files in it with no subfolders and it was almost inaccessible before the Diskeeper implementation due to the fragmentation level being very high”

Two Benefits of V-locity on Virtual Platforms

by karen 16. August 2011 03:36

A major concern with virtual guest operating systems in a virtualized environment is the possible resource contention introduced as each virtual guest operates independent of the others.

With respect to storage, Diskeeper Corporation’s V-locity 3.0 virtual platform disk optimizer mitigates over-utilization in two ways:

First, each V-locity Guest installation coordinates resource scheduling with a centrally installed V-locity Host Agent.  These guests automatically discover the V-locity Host Agent following installation. Once connected together in this fashion, V-locity Guests cooperate to complete each of their defragmentation tasks in a manner most efficient to the virtual server's resources as a whole.  

Second, the automatic zeroing of free space feature ensures that unused space on virtual drives is zeroed out and compacted in such a way that when a virtual guest is migrated to a different virtual server via VMotion, only the allocated data is transferred.  This speeds up the VMotion process and decreases the load on the shared storage subsystem.

RainWorx specializes in Online Auction Software.  Our hosted web sites are mostly our Auction Software customers.  As such, every auction listing (for each customer, on each server) has one or more images associated, so we have a very high volume of images being uploaded which could potentially create a lot of fragmentation.

Diskeeper Extremely Shortened and Kept Backup Times Minimized

by Colleen Toumayan 5. April 2011 05:22

Daiwa Odakyu Construction Co., Ltd.  

Problem 

Daiwa Odakyu Construction Co., Ltd did back up of 15 Servers every day using Symantec Backup Exec. But the problem of latency of backup appeared. Initially the system was designed to finish backup within 3 hours at most. But the time grew to 8 hours. They thought additional hardware was needed but had no additional budget. At that time they discovered the cause of latency was fragmentation. First they tried to solve fragments with the built-in defrag. But it solved only 20%. Next a free defrag software was tried. It proceeded to 35% and shortened backup time by more than 1 hour. But 2 days after, the backup time got back to 8 hours. 

Solution 

Mr. Kawata, manager of the Information System Group of Daiwa Odakyu, found Diskeeper® via the internet and downloaded trialware from SOHEI. Diskeeper solved all fragmentation and shortened the backup times down to 1.3 hours. What’s more, IntelliWrite® prevented fragmentation up to 99%! In accordance with their trial, the system without Diskeeper added 1 hour a day to their backup times. 

 

Back up Time(hour) Number of Fragments Number of fragments prevented
Initial design 3.0 - -
Fragmented 8.5 10,000,000以上 -
After defrag by Diskeeper 1.3 250 3,000,0007,200,000
Improvement 85% 99.9975% (断片化防止率99%)

 “I couldn’t estimate such a big influence of fragmentation in the 50% used volume.  The incredible power of Diskeeper is surprising me. The massive fragmentation I gave up trying to solve is now easily defragmented and prevented by Diskeeper, and then this leads to prevent latency of back up completely.  

“The trial without Diskeeper, which resulted in adding 1 hour a day to backup time, scared me so much. With increasing numbers of files, the backup caused massive fragmentation and gets into a dangerous situation. Less than $1,000 investment in Diskeeper is equal to more than $10,000 worth of Servers. I think Diskeeper is vital for file servers and backup servers."  

“I’m thankful to the developers of this surprising software.”
