What Condusiv’s Diskeeper Does for Me

by Tim Warner, Microsoft Cloud & Datacenter MVP 4. November 2019 05:36

I'm a person who uses what he has. For example, my friend Roger purchased a fancy new keyboard, but only uses it on "special occasions" because he wants to keep the hardware in pristine condition. That isn't me--my stuff wears out because I rely on it and use it continuously.

To this point, the storage on my Windows 10 workstation computer takes a heavy beating because I read and write data to my hard drives every single day. I have quite an assortment of fixed drives on this machine:

·         mechanical hard disk drive (HDD)

·         "no moving parts" solid state drive (SSD)

·         hybrid SSD/HDD drive

Today I'd like to share with you some ways that Condusiv’s Diskeeper helps me stay productive. Trust me--I'm no salesperson. Condusiv isn't paying me to write this article. My goal is to share my experience with you so you have something to think about in terms of disk optimization options for your server and workstation storage.

Diskeeper® or SSDKeeper®?

I've used Diskeeper on my servers and workstations since 2000. How time flies! A few years ago it confused me when Condusiv released SSDkeeper, their SSD optimization tool that works by optimizing your data as its written to disk.

Specifically, my confusion lay in the fact you can't have Diskeeper and SSDkeeper installed on the same machine simultaneously. As you saw, I almost always have a mixture of HDD and SSD drives. What am I losing by installing either Diskeeper or SSDkeeper, but not both?

You lose nothing because Diskeeper and SSDkeeper share most of the same features. Diskeeper like SSDkeeper can optimize solid-state disks using IntelliMemory Caching and IntelliWrite, and SSDkeeper like Diskeeper can optimize magnetic disks using Instant Defrag. Both products can automatically determine the storage type and apply the optimal technology.

Thus, your decision of whether to purchase Diskeeper or SSDkeeper is based on which technology the majority of your disks use, either HDD or SSD.

Allow me to explain what those three product features mean in practice:

·         IntelliMemory®: Uses unallocated system random access memory (RAM) for disk read caching

·         IntelliWrite®: Prevents fragmentation in the first place by writing data sequentially to your hard drive as its

created

·         Instant Defrag™: Uses a Windows service to perform "just in time" disk defragmentation

In Diskeeper, click Settings > System > Basic to verify you're taking advantage of these features. I show you the interface in Figure 1.

What about external drives?

In Condusiv's Top FAQs document you'll note that Diskeeper no longer supports external drives. Their justification for this decision is that their customers generally do not use external USB drives for high performance, input/output (I/O) intensive applications.

If you want to run optimization on external drives, you can do that graphically with the Optimize Drives Windows 10 utility, or you can run defrag.exe from an elevated command prompt.

For example, here I am running a fragmentation analysis on my H: volume, an external SATA HDD:

PS C:\users\tim> defrag H: /A

Microsoft Drive Optimizer

Copyright (c) Microsoft Corp.

Invoking analysis on TWARNER1 (H:)...

The operation completed successfully.

Post Defragmentation Report:

         Volume Information:

                Volume size                 = 1.81 TB

                Free space                  = 1.44 TB

                Total fragmented space      = 0%

                Largest free space size     = 1.43 TB

         Note: File fragments larger than 64MB are not included in the fragmentation statistics.

         You do not need to defragment this volume.

PS C:\users\tim>              

Let's look at the numbers!

All Condusiv products make it simple to perform benchmark analyses and run progress reports, and Diskeeper is no exception to this rule. Look at Figure 2--since I rebuilt my Windows 10 workstation and installed Diskeeper in July 2018, I've saved over 20 days of storage I/O time!

Figure 2. Diskeeper dashboard.

Those impressive I/O numbers don't strain credulity when you remember that Diskeeper aggregates I/O values across all my fixed drives, not only one. This time saving is the chief benefit Diskeeper gives me as a working IT professional. The tool gives me back seconds that otherwise I'd spend waiting on disk operations to complete; I then can use that time for productive work instead.

Even more to the point, Diskeeper does this work for me in the background, without my having to remember to run or even schedule defragmentation and optimization jobs. I'm a huge fan of Diskeeper, and I hope you will be.

Finance Company Deploys V-locity I/O Reduction Software for Blazing Fast VDI

by Dawn Richcreek 27. November 2018 05:27

When the New Mexico Mortgage Finance Authority decided to better support their users by moving away from using physical PCs and migrating to a virtual desktop infrastructure, the challenge was to ensure the fastest possible user experience from their Horizon View VDI implementation.

“Anytime an organization starts talking about VDI, the immediate concern in the IT shop is how well we will be able to support it from a performance standpoint to ensure a pristine end user experience. Although supported by EMC VNXe flash storage with high IOPS, one of our primary concerns had to do with Windows write inefficiencies that chews up a large percentage of flash IOPS unnecessarily. When you’re rolling out a VDI initiative, the one thing you can’t afford to waste is IOPS,” said Joseph Navarrete, CIO, MFA.

After Joseph turned to Condusiv’s “Set-It-and-Forget-It®” V-locity® I/O reduction software and bumped up the memory allocation for his VDI instances, V-locity was able to offload 40% of I/O from storage resulting in a much faster VDI experience to his users. When he demo’d V-locity on his MS-SQL server instances, V-locity eliminated 39% of his read I/O traffic from storage due to DRAM read caching and another 40% of write I/O operations by solving Windows write inefficiencies at the source.

After seeing the performance boost and increased efficiency to his hardware stack, Joseph ensured V-locity was running across all his systems like MS-Exchange, SharePoint, and more.

“With V-locity I/O reduction software running on our VDI instances, users no longer have to wait extra time. The same is now true for our other mission critical applications like MS-SQL. The dashboard within the V-locity UI provides all the necessary analytics about our environment and view into what the software is actually doing for us. The fact that all of this runs quietly in the background with near-zero overhead impact and no longer requires a reboot to install or upgrade makes the software truly “set and forget,” said Navarrete.

Fix SQL Server Storage Bottlenecks

by Spencer Allingham 23. October 2018 20:58

No SQL code changes.
No Disruption.
No Reboots.
Simple!

 

Condusiv V-locity Introduction

 

 

Whether running SQL in a physical or virtualized environment, most SQL DBAs would welcome faster storage at a reasonable price.

The V-locity® software from Condusiv® Technologies is designed to provide exactly that, but using the storage hardware that you already own. It doesn't matter if you have direct attached disks, if you're running a tiered SAN, have a tray of SSD storage or are fortunate enough to have an all-flash array; that storage layer can be a limiting factor to your SQL Server database productivity.

The V-locity software reduces the amount of storage I/O traffic that has to go out and be processed by the disk storage layer, and streamlines or optimizes the data which does have to still go out to disk.

The net result is that SQL can typically get more transactions completed in the same amount of time, quite simply because on average, it's not having to wait so much on the storage before being able to get on with its next transaction.

V-locity can be downloaded and installed without any disruption to live SQL servers. No SQL code changes are required and no reboots. Just install and typically you'll start seeing results in just a few minutes.

Microsoft SQL Server I/O Reliability Certification LogoBefore we take a more in-depth look at that, I would like to briefly mention that last year, the V-locity software was awarded the Microsoft SQL Server I/O Reliability Certification. This means that whilst providing faster storage access, V-locity didn't adversely affect the required and recommended behaviors that an I/O subsystem must provide for SQL Server, as defined by Microsoft themselves.

Microsoft ran tests for this in Azure, with SQL 2016, and used HammerDB to generate an online transaction processing type workload. Not only was V-locity able to jump through all the hoops necessary to achieve the certification, but it was also able to show an increase of about 30% more SQL transactions in the same amount of time.

In this test, that meant roughly 30% more orders processed.

They probably could have processed more too, if they had allowed V-locity a slightly larger RAM cache size.

Use the V-locity software to not only identify those servers that cause storage I/O issues, but fix those issues at the same time.

Financial Sector Battered by Rising Compliance Costs

by Dawn Richcreek 15. August 2018 08:39

Finance is already an outlier in terms of IT costs. The industry devotes 10.5% of total revenue to IT—and on average, each financial industry IT staffer supports only 15.7 users, the fewest of any industry.

All over the world, financial services companies are facing skyrocketing compliance costs. Almost half the respondents to a recent Accenture survey of compliance officers in 13 countries said they expected 10% to 20% increases, and nearly one in five are expecting increases of more than 20%.

Much of this is driven by international banking regulations. At the beginning of this year, the Common Reporting Standard went into effect. An anti-tax-evasion measure signed by 142 countries, the CRS requires financial institutions to provide detailed account information to the home governments of virtually every sizeable depositor.

Just to keep things exciting, the U.S. government hasn’t signed on to CRS; instead we require banks doing business with Americans to comply with the Foreign Account Tax Compliance Act of 2010. Which requires—surprise, surprise—pretty much the same thing as CRS, but reported differently.

And these are just two examples of the compliance burden the financial sector must deal with. Efficiently, and within a budget. In a recent interview by ValueWalk entitled “Compliance Costs Soaring for Financial Institutions,” Condusiv® CEO Jim D’Arezzo said, “Financial firms must find a path to more sustainable compliance costs.”

Speaking to the site’s audience (ValueWalk is a site focused on hedge funds, large asset managers, and value investing) D’Arezzo noted that finance is already an outlier in terms of IT costs. The industry devotes 10.5% of total revenue to IT, more than government, healthcare, retail, or anybody else. It’s also an outlier in terms of IT staff load; on average, each financial industry IT staffer supports only 15.7 users, the fewest of any industry. (Government averages 37.8 users per IT staff employee.)

To ease these difficulties, D’Arezzo recommends that the financial industry consider advanced technologies that provide cost-effective ways to enhance overall system performance. “The only way financial services companies will be able to meet the compliance demands being placed on them, and at the same time meet their efficiency and profitability targets, will be to improve the efficiency of their existing capacity—especially as regards I/O reduction.”

At Condusiv, that’s our business. We’ve seen users of our I/O reduction software solutions increase the capability of their storage and servers, including SQL servers, by 30% to 50% or more. In some cases, we’ve seen results as high as 10X initial performance—without the need to purchase a single box of new hardware.

If you’re interested in working with a firm that can reduce your two biggest silent killers of SQL performance, request a demo with an I/O performance specialist now.

Which Processes are Using All of My System Resources?

by Gary Quan 17. July 2018 05:50

Over time as more files and applications are added to your system, you notice that performance has degraded, and you want to find out what is causing it. A good starting point is to see how the system resources are being used and which processes and/or files are using them.

Both Diskeeper® and SSDkeeper® contain a lesser known feature to assist you on this. It is called the System Monitoring Report which can show you how the CPU and I/O resources are being utilized, then digging down a bit deeper, which processes or files are using them.

Under Reports on the Main Menu, the System Monitoring Report provides you with data on the system’s CPU usage and I/O Activity.

 

The CPU Usage report takes the average CPU usage from the past 7 days, then provides a graph of the hourly usage on an average day. You can then see at which times the CPU resources are being hit the most and by how much.

Digging down some more, you can then see which processes utilized the most CPU resources.

 

The Disk I/O Activity report takes the average disk I/O activity from the past 7 days, then provides a graph of the hourly activity on an average day. You can then determine at which times the I/O activity is the highest.

Digging down some more, you can then see which processes utilized the I/O resources the most, plus what processes are causing the most split (extra) I/Os.

 

You can also see which file types have the highest I/O utilization as well as those causing the most split (extra) I/Os.  This can help indicate what files and related processes are causing this type of extra I/O activity.

 

So, if you are trying to see how your system is being used, maybe for performance issues, this report gives you a quick and easy look on how the CPU and Disk I/O resources are being used on your system and what processes and file types are using them. This along with some other Microsoft Utilities, like Task Manager and Performance Monitor can help you tune your system for optimum performance.
