Collecting Transaction Per Minute from SQL Server and HammerDB

Storage I/O trends

Collecting Transaction Per Minute from SQL Server and HammerDB

When using benchmark or workload generation tools such as HammerDB I needed a way to capture and log performance activity metrics such as transactions per minute. For example using HammerDB to simulate an application making database requests performing various transactions as part of testing an overall system solution including server and storage I/O activity. This post takes a look at the problem or challenge I was looking to address, as well as creating a solution after spending time searching for one (still searching btw).

The Problem, Issue, Challenge, Opportunity and Need

The challenge is to collect application performance such as transactions per minute from a workload using a database. The workload or benchmark tool (in this case HammerDB) is the System Test Initiator (STI) that drives the activity (e.g. database requests) to a System Under Test (SUT). In this example the SUT is a Microsoft SQL Server running on a Windows 2012 R2 server. What I need is to collect and log into a file for later analysis the transaction rate per minute while the STI is generating a particular workload.

Server Storage I/O performance

Understanding the challenge and designing a strategy

If you have ever used benchmark or workload generation tools such as Quest Benchmark Factory (part of the Toad tools collection) you might be spoiled with how it can be used to not only generate the workload, as well as collect, process, present and even store the results for database workloads such as TPC simulations. In this situation, Transaction Processing Council (TPC) like workloads need to be run and metrics on performance collected. Lets leave Benchmark Factory for a future discussion and focus instead on a free tool called HammerDB and more specifically how to collection transactions per minute metrics from Microsoft SQL Server. While the focus is SQL Server, you can easily adapt the approach for MySQL among others, not to mention there are tools such as Sysbench, Aerospike among other tools.

The following image (created using my Livescribe Echo digital pen) outlines the problem, as well as sketches out a possible solution design. In the following figure, for my solution I’m going to show how to grab every minute for a given amount of time the count of transactions that have occurred. Later in the post processing (you could also do in the SQL Script) I take the new transaction count (which is cumulative) and subtract the earlier interval which yields the transactions per minute (see examples later in this post).

collect TPM metrics from SQL Server with hammerdb
The problem and challenge, a way to collect Transactions Per Minute (TPM)

Finding a solution

HammerDB displays results via its GUI, and perhaps there is a way or some trick to get it to log results to a file or some other means, however after searching the web, found that it was quicker to come up with solution. That solution was to decide how to collect and report the transactions per minute (or you could do by second or other interval) from Microsoft SQL Server. The solution was to find what performance counters and metrics are available from SQL Server, how to collect those and log them to a file for processing. What this means is a SQL Server script file would need to be created that ran in a loop collecting for a given amount of time at a specified interval. For example once a minute for several hours.

Taking action

The following is a script that I came up with that is far from optimal however it gets the job done and is a starting point for adding more capabilities or optimizations.

In the following example, set loopcount to some number of minutes to collect samples for. Note however that if you are running a workload test for eight (8) hours with a 30 minute ramp-up time, you would want to use a loopcount (e.g. number of minutes to collect for) of 480 + 30 + 10. The extra 10 minutes is to allow for some samples before the ramp and start of workload, as well as to give a pronounced end of test number of samples. Add or subtract however many minutes to collect for as needed, however keep this in mind, better to collect a few extra minutes vs. not have them and wished you did.

-- 
DECLARE @cntr_value bigint;
DECLARE @loopcount bigint; # how many minutes to take samples for

set @loopcount = 240

SELECT @cntr_value = cntr_value
 FROM sys.dm_os_performance_counters
 WHERE counter_name = 'transactions/sec'
 AND object_name = 'MSSQL$DBIO:Databases'
 AND instance_name = 'tpcc' ; print @cntr_value;
 WAITFOR DELAY '00:00:01'
-- 
-- Start loop to collect TPM every minute
-- 

while @loopcount <> 0
begin
SELECT @cntr_value = cntr_value
 FROM sys.dm_os_performance_counters
 WHERE counter_name = 'transactions/sec'
 AND object_name = 'MSSQL$DBIO:Databases'
 AND instance_name = 'tpcc' ; print @cntr_value;
 WAITFOR DELAY '00:01:00'
 set @loopcount = @loopcount - 1
end
-- 
-- All done with loop, write out the last value
-- 
SELECT @cntr_value = cntr_value
 FROM sys.dm_os_performance_counters
 WHERE counter_name = 'transactions/sec'
 AND object_name = 'MSSQL$DBIO:Databases'
 AND instance_name = 'tpcc' ; print @cntr_value;
-- 
-- End of script
--

The above example has loopcount set to 240 for a 200 minute test with a 30 minute ramp and 10 extra minutes of samples. I use the a couple of the minutes to make sure that the system test initiator (STI) such as HammerDB is configured and ready to start executing transactions. You could also put this along with your HammerDB items into a script file for further automation, however I will leave that exercise up to you.

For those of you familiar with SQL and SQL Server you probably already see some things to improve or stylized or simply apply your own preference which is great, go for it. Also note that I’m only selecting a certain variable from the performance counters as there are many others which you can easily discovery with a couple of SQL commands (e.g. select and specify database instance and object name. Also note that the key is accessing the items in sys.dm_os_performance_counters of your SQL Server database instance.

The results

The output from the above is a list of cumulative numbers as shown below which you will need to post process (or add a calculation to the above script). Note that part of running the script is specifying an output file which I show later.

785
785

785
37142
1259026
2453479
3635138

Implementing the solution

You can setup the above script to run as part of a larger automation shell or batch script, however for simplicity I’m showing it here using Microsoft SQL Server Studio.

The following image shows how to specify an output file for the results to be logged to when using Microsoft SQL Studio to run the TPM collection script.

With the SQL Server script running to collect results, and HammerDB workload running to generate activity, the following shows Quest Spotlight on Windows (SoW) displaying WIndows Server 2012 R2 operating system level performance including CPU, memory, paging and other activity. Note that this example had about the system test initiator (STI) which is HammerDB and the system under test (SUT) that is Microsoft SQL Server on the same server.

Results and post-processing

As part of post processing simple use your favorite tool or script or what I often do is pull the numbers into Excel spreadsheet, and simply create a new column of numbers that computes and shows the difference between each step (see below). While in Excel then I plot the numbers as needed which can also be done via a shell script and other plotting tools such as R.

In the following example, the results are imported into Excel (your favorite tool or script) where I then add a column (B) that simple computes the difference between the existing and earlier counter. For example in cell B2 = A2-A1, B3 = A3-A2 and so forth for the rest of the numbers in column A. I then plot the numbers in column B to show the transaction rates over time that can then be used for various things.

Note that in the above results that might seem too good to be true they are, these were cached results to show the tools and data collection process as opposed to the real work being done, at least for now…

The SSD Place (collection of flash and SSD resources)

I/O, I/O how well do you know about good or bad server and storage I/Os?

What this all means and wrap-up

There are probably many ways to fine tune and optimize the above script, likewise there may even be some existing tool, plug-in, add-on module, or configuration setting that allows HammerDB to log the transaction activity rates to a file vs. simply showing on a screen. However for now, this is a work around that I have found for when needing to collect transaction activity performance data with HammerDB and SQL Server.

Ok, nuff said, for now…

Cloud conversations: If focused on cost you might miss other cloud storage benefits

Storage I/O trends

Cloud conversations: If focused on cost you might miss other cloud storage benefits

Drew Robb (@robbdrew) has a good piece (e.g. article) over at InfoStor titled Eight Ways to Avoid Cloud Storage Pricing Surprises that you can read here.

Drew start’s his piece out with this nice analogy or story:

Let’s begin with a cautionary tale about pricing: a friend hired a moving company as they quoted a very attractive price for a complex move. They lured her in with a low-ball price then added more and more “extras” to the point where their price ended up higher than many of the other bids she passed up. And to make matters worse, they are already two weeks late with delivery of the furniture and are saying it might take another two weeks.

Drew extends his example in his piece to compare how some cloud providers may start with pricing as low as some amount only for the customer to be surprised when they did not do their homework to learn about the various fees.

Note that most reputable cloud providers do not hide their fees even though there are myths that all cloud vendors have hidden fees, instead they list what those costs are on their sites. However that means the smart shopper or person procuring cloud services needs to go look for those fee’s and what they mean to avoid surprises. On the other hand if you can not find what extra fee’s would be along with what is or is not included in a cloud service price, to quote Jenny’s line in the movie Forest Gump, "…Run, Forest! Run!…".

In Drew’s piece he mentions five general areas to keep an eye on pertaining cloud storage costs including:

  • Be Duly Diligent
  • Trace Out Application Interaction
  • Avoid Fixed Usage Rates
  • Beware Lowballing
  • Demand Enterprise Visibility

Beware Lowballing

In Drew’s piece, he includes a comment from myself shown below.

Just as in the moving business, lowballing is alive and well in cloud pricing. Greg Schulz, an analyst with StorageIO Group, warned users to pay attention to services that have very low-cost per GByte/TByte yet have extra fees and charges for use, activity or place service caps. Compare those with other services that have higher base fees and attempt to price it based on your real storage and usage patterns.

“Watch out for usage and activity fees with lower cost services where you may get charged for looking at or visiting your data, not to mention for when you actually need to use it,” said Schulz. “Also be aware of limits or caps on performance that may apply to a particular class of service.”

As a follow-up to Drew’s good article, I put together the following thoughts that appeared earlier this year over at InfoStor titled Cloud storage: Is It All About Cost? that you can read here. In that article I start out with the basic question of:

So what is your take on cloud storage, and in what context?

Is cloud storage all about removing cost, cost cutting, free storage?

Or perhaps even getting something else in addition to free storage?

I routinely talk with different people from various backgrounds, environments from around the world, and the one consistency I hear when it comes to cloud services including storage is that there is no consistency.

What I mean by this is that there are the cloud crowd cheerleaders who view or cheer for anything cloud related, some of them actually use the cloud vs. simply cheering.

What does this have to do with cloud costs

Simple, how do you know if cloud is cheaper or more expensive if you do not know your own costs?

How do you know if cloud storage is available, reliable, durable if you do not have a handle on your environment?

Are you making apples to oranges comparisons or simple trading or leveraging hype and fud for or against?

Similar to regular storage, how you choose to use and configure on-site traditional storage for high-availability, performance, security among other best practices should be applied to cloud solutions. After all, only you can prevent cloud (or on premise) data loss, granted it is a shared responsibility. Shared responsibility means your service provider or system vendor needs to deliver quality robust solution that you can then take responsibility for configure to use with resiliency.

For some of you perhaps cloud might be about lowering, reducing or cutting storage costs, perhaps even getting some other service(s) in addition to free storage.

On the other hand, some of you might be

Yet another class of cloud storage (e.g. AWS EBS) are those intended or optimized to be accessed from within a cloud via cloud servers or compute instances (e.g. AWS EC2 among others) vs. those that are optimized for both inside the cloud as well as outside the cloud access (e.g. AWS S3 or Glacier with costs shown here). I am using AWS examples; however, you could use Microsoft Azure (pricing shown here), Google (including their new Nearline service with costs shown here), Rackspace, (calculator here or other cloud files pricing here), HP Cloud (costs shown here), IBM Softlayer (object storage costs here) and many others.

Not all types of cloud storage are the same, which is similar to traditional storage you may be using or have used in your environment in the past. For example, there is high-capacity low-cost storage, including magnetic tape for data protection, archiving of in-active data along with near-line hard disk drives (HDD). There are different types of HDDs, as well as fast solid-state devices (SSD) along with hybrid or SSHD storage used for different purposes. This is where some would say the topic of cloud storage is highly complex.

What this means

In my opinion there are cheap clouds (products, services, solutions) and there are low-cost options as well as there are value and premium offerings. Avoid confusing value with cheap or low-cost as something might have a higher cost, however including more capabilities or fees included that if useful can be more value. Look beyond the up-front cost aspects of clouds also considering ongoing recurring fees for actually using a server or solution.

If you can find low-cost storage at or below a penny per GByte per month that could be a good value if it also includes many free access, retrieval GETS head and lists for management or reporting. On the other hand, if you find a service that is at or below a penny per GByte per month however charges for any access including retrieval, as well as network bandwidth fees along with reporting, that might not be as good of a value.

Look beyond the basic price and watch out for statements like "…as low as…" to understand what is required to get that "..as low as.." price. Also understand what the extra fee’s are which most of the reputable providers list these on their sites, granted you have to look for them. If you are already using cloud services, pay attention to your monthly invoices and track what you are paying for to avoid surprises.

From my InfoStor piece:

For cloud storage, instead of simply focusing on lowest cost of storage per capacity, look for value, along with ability to configure or use with as much resiliency as you need. Value will mean different things depending on your needs and cloud storage servers, yet the solution should be cost-effective with availability including durability, secure and applicable performance.

Shopping for cloud servers and storage is similar to acquiring regular servers and storage in that you need to understand what you are acquiring along with up-front and recurring fee’s to understand the total cost of ownership and cost of operations not to mention making apples to apples vs. apples to oranges comparisons.

Btw, instead of simply using lower cost cloud services to cut cost, why not also use those capabilities to create or park another copy of your important data somewhere else just to be safe…

What say you about cloud costs?

Ok, nuff said, for now…

    VMware announces vSphere V6 and associated virtualization technologies

    VMware announces vSphere V6 and associated virtualization technologies

    server storage I/O trends

    VMware has announced version 6 (V6) of its software defined data center (SDDC) server virtualization hypervisor called vSphere aka ESXi. In addition to a new version of its software defined server hypervisor along with companion software defined management and convergence tools.

    VMware

    VMware vSphere Refresh

    As a refresh for those whose world does not revolve around VMware, vSphere and software defined data centers (believe it or not there are some who exist ;), ESXi is the hypervisor that virtualizes underlying physical machines (PM’s) known as hosts.

    software defined data center convergence
    The path to software defined data center convergence

    Guest operating systems (or other hypervisors using nesting) run as virtual machines (VM’s) on top of the vSphere hypervisor host (e.g. ESXi software). Various VMware management tools (or third-party) are used for managing the virtualized data center from initial configuration, configuration, conversion from physical to virtual (P2V) or virtual to virtual (V2V) along with data protection, performance, capacity planning across servers, storage and networks.

    virtual machines

    VMware vSphere is flexible and can adapt to different sized environments from small office home office (SOHO) or small SMB, to large SMB, SME, enterprise or cloud service provider. There are a free version of ESXi along with paid versions that include support and added management tool features. Besides the ESXi vSphere hypervisor, other commonly deployed modules include the vCenter administration along with Infrastructure Controller services platform among others. In addition, there are optional solution bundles to add support for virtual networking, cloud (public and private), data protection (backup/restore, replication, HA, BC, DR), big data among other capabilities.

    What is new with vSphere V6

    VMware has streamlined the installation, configuration and deployment of vSphere along with associated tools which for smaller environments makes things simply easier. For the larger environments, having to do less means being able to do more in the same amount of time which results in cost savings. In addition to easier to use, deploy and configure, VMware has extended the scaling capabilities of vSphere in terms of scaling-out (larger clusters), scaling-up (more and larger servers), as well as scaling-down (smaller environments and ease of use).

    cloud virtual software defined servers

    • Compute: Expanded support for new hardware, guest operating systems and general scalability in terms of physical, and virtual resources. For example increasing the number of virtual CPU (vCPUs), number of cluster nodes among other speeds and feeds enhancements.

    server storage I/O vsan

    • Storage: This is an area where several enhancements were made including updates for Storage I/O controls (Storage QoS and performance optimizations) with per VM reservations, NFS v4.1 with Kerberos client, Virtual SAN (VSAN) improvements (new back-end underlying file system) as well as new Virtual Volumes (vVOLs) for Storage Policy Based Management.
    • Availability: Improvements for vMotion (ability to live move virtual machines between physical servers (vmware hosts) including long distance fault-tolerance. Other improvements include faster replication, vMotion across vCenter servers, and long distance vMotion (up to 100ms round trip time latency).
    • Network: Network I/O Control (NIOC) provides per VM and dat (VM and data repository) bandwidth reservations for quality of service (QoS) performance optimization.
    • Management: Improvements for multi-site, virtual data centers, content-library (storage and versioning of files and objects including ISOs and OVFs (Open Virtualization Format files) that can be on a VMFS (VMware File System) dat or NFS volume, policy-based management and web-client performance enhancements.

    What is vVOL?

    The quick synopsis of VMware vVOL’s overview:

    • Higher level of abstraction of storage vs. traditional SCSI LUN’s or NAS NFS mount points
    • Tighter level of integration and awareness between VMware hypervisors and storage systems
    • Simplified management for storage and virtualization administrators
    • Removing complexity to support increased scaling
    • Enable automation and service managed storage aka software defined storage management

    vVOL’s are not LUN’s like regular block (e.g. DAS or SAN) storage that use SAS, iSCSI, FC, FCoE, IBA/SRP, nor are they NAS volumes like NFS mount points. Likewise vVOL’s are not accessed using any of the various object storage access methods mentioned above (e.g. AWS S3, Rest, CDMI, etc) instead they are an application specific implementation. For some of you this approach of an applications specific or unique storage access method may be new, perhaps revolutionary, otoh, some of you might be having a DejaVu moment right about now.

    vVOL is not a LUN in the context of what you may know and like (or hate, even if you have never worked with them), likewise it is not a NAS volume like you know (or have heard of), neither are they objects in the context of what you might have seen or heard such as S3 among others.

    Keep in mind that what makes up a VMware virtual machine are the VMK, VMDK and some other files (shown in the figure below), and if enough information is known about where those blocks of data are or can be found, they can be worked upon. Also keep in mind that at least near-term, block is the lowest common denominator that all file systems and object repositories get built-up.

    server storage I/O vVOL basics
    How VMware data storage accessed and managed with vVOLs (read more here)

    Here is the thing, while vVOL’s will be accessible via a block interface such as iSCSI, FC or FCoE or for that matter, over Ethernet based IP using NFS. Think of these storage interfaces and access mechanisms as the general transport for how vSphere ESXi will communicate with the storage system (e.g. their data path) under vCenter management.

    What is happening inside the storage system that will be presented back to ESXi will be different than a normal SCSI LUN contents and only understood by VMware hypervisor. ESXi will still tell the storage system what it wants to do including moving blocks of data. The storage system however will have more insight and awareness into the context of what those blocks of data mean. This is how the storage systems will be able to more closely integrate snapshots, replication, cloning and other functions by having awareness into which data to move, as opposed to moving or working with an entire LUN where a VMDK may live.

    Keep in mind that the storage system will still function as it normally would, just think of vVOL as another or new personality and access mechanism used for VMware to communicate and manage storage. Watch for vVOL storage provider support from the who’s who of existing and startup storage system providers including Cisco, Dell, EMC, Fujitsu, HDS, HP, IBM, NetApp, Nimble and many others. Read more about Storage I/O fundamentals here and vVOLs here and here.

    What this announcement means

    Depending on your experiences, you might use revolutionary to describe some of the VMware vSphere V6 features and functionalities. Otoh, if you have some Dejavu moments looking pragmatically at what VMware is delivering with V6 of vSphere executing on their vision, evolutionary might be more applicable. I will leave it up to you do decide if you are having a Dejavu moment and what that might pertain to, or if this is all new and revolutionary, or something more along the lines of technolutionary.

    VMware continues to execute delivering on the Virtual Data Center aka Software Defined Data Center paradigm by increasing functionality, as well as enhancing existing capabilities with performance along with resiliency improvements. These abilities enable the aggregation of compute, storage, networking, management and policies for enabling a global virtual data center while supporting existing along with new emerging applications.

    Server and Storage I/O Benchmarking 101 for Smarties

    Server Storage I/O Benchmarking 101 for Smarties or dummies ;)

    server storage I/O trends

    This is the first of a series of posts and links to resources on server storage I/O performance and benchmarking (view more and follow-up posts here).

    The best I/O is the I/O that you do not have to do, the second best is the one with the least impact as well as low overhead.

    server storage I/O performance

    Drew Robb (@robbdrew) has a Data Storage Benchmarking Guide article over at Enterprise Storage Forum that provides a good framework and summary quick guide to server storage I/O benchmarking.

    Via Drew:

    Data storage benchmarking can be quite esoteric in that vast complexity awaits anyone attempting to get to the heart of a particular benchmark.

    Case in point: The Storage Networking Industry Association (SNIA) has developed the Emerald benchmark to measure power consumption. This invaluable benchmark has a vast amount of supporting literature. That so much could be written about one benchmark test tells you just how technical a subject this is. And in SNIA’s defense, it is creating a Quick Reference Guide for Emerald (coming soon).

    But rather than getting into the nitty-gritty nuances of the tests, the purpose of this article is to provide a high-level overview of a few basic storage benchmarks, what value they might have and where you can find out more. 

    Read more here including some of my comments, tips and recommendations.

    Drew’s provides a good summary and overview in his article which is a great opener for this first post in a series on server storage I/O benchmarking and related resources.

    You can think of this series (along with Drew’s article) as server storage I/O benchmarking fundamentals (e.g. 101) for smarties (e.g. non-dummies ;) ).

    Note that even if you are not a server, storage or I/O expert, you can still be considered a smarty vs. a dummy if you found the need or interest to read as well as learn more about benchmarking, metrics that matter, tools, technology and related topics.

    Server and Storage I/O benchmarking 101

    There are different reasons for benchmarking, such as, you might be asked or want to know how many IOPs per disk, Solid State Device (SSD), device or storage system such as for a 15K RPM (revolutions per minute) 146GB SAS Hard Disk Drive (HDD). Sure you can go to a manufactures website and look at the speeds and feeds (technical performance numbers) however are those metrics applicable to your environments applications or workload?

    You might get higher IOPs with smaller IO size on sequential reads vs. random writes which will also depend on what the HDD is attached to. For example are you going to attach the HDD to a storage system or appliance with RAID and caching? Are you going to attach the HDD to a PCIe RAID card or will it be part of a server or storage system. Or are you simply going to put the HDD into a server or workstation and use as a drive without any RAID or performance acceleration.

    What this all means is understanding what it is that you want to benchmark test to learn what the system, solution, service or specific device can do under different workload conditions.

    Some benchmark and related topics include

    • What are you trying to benchmark
    • Why do you need to benchmark something
    • What are some server storage I/O benchmark tools
    • What is the best benchmark tool
    • What to benchmark, how to use tools
    • What are the metrics that matter
    • What is benchmark context why does it matter
    • What are marketing hero benchmark results
    • What to do with your benchmark results

      • server storage I/O benchmark step test
      Example of a step test results with various workers and workload

    • What do the various metrics mean (can we get a side of context with them metrics?)
    • Why look at server CPU if doing storage and I/O networking tests
    • Where and how to profile your application workloads
    • What about physical vs. virtual vs. cloud and software defined benchmarking
    • How to benchmark block DAS or SAN, file NAS, object, cloud, databases and other things
    • Avoiding common benchmark mistakes
    • Tips, recommendations, things to watch out for
    • What to do next

    Wrap up and summary

    We have just scratched the surface when it comes to benchmarking cloud, virtual and physical server storage I/O and networking hardware, software along with associated tools, techniques and technologies. However hopefully this and the links for more reading mentioned above give a basis for connecting the dots of what you already know or enable learning more about workloads, synthetic generation and real-world workloads, benchmarks and associated topics. Needless to say there are many more things that we will cover in future posts (e.g. keep an eye on and bookmark the server storage I/O benchmark tools and resources page here).

    Server Storage I/O Benchmark Tools: Microsoft Diskspd (Part I)

    Server Storage I/O Benchmark Tools: Microsoft Diskspd (Part I)

    server storage I/O trends

    This is part-one of a two-part post pertaining Microsoft Diskspd.that is also part of a broader series focused on server storage I/O benchmarking, performance, capacity planning, tools and related technologies. You can view part-two of this post here, along with companion links here.

    Background

    Many people use Iometer for creating synthetic (artificial) workloads to support benchmarking for testing, validation and other activities. While Iometer with its GUI is relatively easy to use and available across many operating system (OS) environments, the tool also has its limits. One of the bigger limits for Iometer is that it has become dated with little to no new development for a long time, while other tools including some new ones continue to evolve in functionality, along with extensibility. Some of these tools have optional GUI for easy of use or configuration, while others simple have extensive scripting and command parameter capabilities. Many tools are supported across different OS including physical, virtual and cloud, while others such as Microsoft Diskspd are OS specific.

    Instead of focusing on Iometer and other tools as well as benchmarking techniques (we cover those elsewhere), lets focus on Microsoft Diskspd.


    server storage I/O performance

    What is Microsoft Diskspd?

    Microsoft Diskspd is a synthetic workload generation (e.g. benchmark) tool that runs on various Windows systems as an alternative to Iometer, vdbench, iozone, iorate, fio, sqlio among other tools. Diskspd is a command line tool which means it can easily be scripted to do reads and writes of various I/O size including random as well as sequential activity. Server and storage I/O can be buffered file system as well non-buffered across different types of storage and interfaces. Various performance and CPU usage information is provided to gauge the impact on a system when doing a given number of IOP’s, amount of bandwidth along with response time latency.

    What can Diskspd do?

    Microsoft Diskspd creates synthetic benchmark workload activity with ability to define various options to simulate different application characteristics. This includes specifying read and writes, random, sequential, IO size along with number of threads to simulate concurrent activity. Diskspd can be used for testing or validating server and storage I/O systems along with associated software, tools and components. In addition to being able to specify different workloads, Diskspd can also be told which processors to use (e.g. CPU affinity), buffering or non-buffered IO among other things.

    What type of storage does Diskspd work with?

    Physical and virtual storage including hard disk drive (HDD), solid state devices (SSD), solid state hybrid drives (SSHD) in various systems or solutions. Storage can be physical as well as partitions or file systems. As with any workload tool when doing writes, exercise caution to prevent accidental deletion or destruction of your data.


    What information does Diskspd produce?

    Diskspd provides output in text as well as XML formats. See an example of Diskspd output further down in this post.

    Where to get Diskspd?

    You can download your free copy of Diskspd from the Microsoft site here.

    The download and installation are quick and easy, just remember to select the proper version for your Windows system and type of processor.

    Another tip is to remember to set path environment variables point to where you put the Diskspd image.

    Also stating what should be obvious, don’t forget that if you are going to be doing any benchmark or workload generation activity on a system where the potential for a data to be over-written or deleted, make sure you have a good backup and tested restore before you begin, if something goes wrong.


    New to server storage I/O benchmarking or tools?

    If you are not familiar with server storage I/O performance benchmarking or using various workload generation tools (e.g. benchmark tools), Drew Robb (@robbdrew) has a Data Storage Benchmarking Guide article over at Enterprise Storage Forum that provides a good framework and summary quick guide to server storage I/O benchmarking.




    Via Drew:

    Data storage benchmarking can be quite esoteric in that vast complexity awaits anyone attempting to get to the heart of a particular benchmark.

    Case in point: The Storage Networking Industry Association (SNIA) has developed the Emerald benchmark to measure power consumption.

    In addition to Drew’s benchmarking quick reference guide, along with the server storage I/O benchmarking tools, technologies and techniques resource page (Server and Storage I/O Benchmarking 101 for Smarties.

    How do you use Diskspd?


    Tip: When you run Microsoft Diskspd it will create a file or data set on the device or volume being tested that it will do its I/O to, make sure that you have enough disk space for what will be tested (e.g. if you are going to test 1TB you need to have more than 1TB of disk space free for use). Another tip is to speed up the initializing (e.g. when Diskspd creates the file that I/Os will be done to) run as administrator.

    Tip: In case you forgot, a couple of other useful Microsoft tools (besides Perfmon) for working with and displaying server storage I/O devices including disks (HDD and SSDs) are the commands "wmic diskdrive list [brief]" and "diskpart". With diskpart exercise caution as it can get you in trouble just as fast as it can get you out of trouble.

    You can view the Diskspd commands after installing the tool and from a Windows command prompt type:

    C:\Users\Username> Diskspd


    The above command will display Diskspd help and information about the commands as follows.

    Microsoft Diskspd (Part II): Server Storage I/O Benchmark Tools

    Microsoft Diskspd (Part II): Server Storage I/O Benchmark Tools

    server storage I/O trends

    This is part-two of a two-part post pertaining Microsoft Diskspd.that is also part of a broader series focused on server storage I/O benchmarking, performance, capacity planning, tools and related technologies. You can view part-one of this post here, along with companion links here.

    Microsoft Diskspd StorageIO lab test drive

    Server and StorageIO lab

    Talking about tools and technologies is one thing, installing as well as trying them is the next step for gaining experience so how about some quick hands-on time with Microsoft Diskspd (download your copy here).

    The following commands all specify an I/O size of 8Kbytes doing I/O to a 45GByte file called diskspd.dat located on the F: drive. Note that a 45GByte file is on the small size for general performance testing, however it was used for simplicity in this example. Ideally a larger target storage area (file, partition, device) would be used, otoh, if your application uses a small storage device or volume, then tune accordingly.

    In this test, the F: drive is an iSCSI RAID protected volume, however you could use other storage interfaces supported by Windows including other block DAS or SAN (e.g. SATA, SAS, USB, iSCSI, FC, FCoE, etc) as well as NAS. Also common to the following commands is using 16 threads and 32 outstanding I/Os to simulate concurrent activity of many users, or application processing threads.
    server storage I/O performance
    Another common parameter used in the following was -r for random, 7200 seconds (e.g. two hour) test duration time, display latency ( -L ) disable hardware and software cache ( -h), forcing cpu affinity (-a0,1,2,3). Since the test ran on a server with four cores I wanted to see if I could use those for helping to keep the threads and storage busy. What varies in the commands below is the percentage of reads vs. writes, as well as the results output file. Some of the workload below also had the -S option specified to disable OS I/O buffering (to view how buffering helps when enabled or disabled). Depending on the goal, or type of test, validation, or workload being run, I would choose to set some of these parameters differently.

    diskspd -c45g -b8K -t16 -o32 -r -d7200 -h -w0 -L -a0,1,2,3 F:\diskspd.dat >> SIOWS2012R203_Eiscsi_145_noh_write000.txt

    diskspd -c45g -b8K -t16 -o32 -r -d7200 -h -w50 -L -a0,1,2,3 F:\diskspd.dat >> SIOWS2012R203_Eiscsi_145_noh_write050.txt

    diskspd -c45g -b8K -t16 -o32 -r -d7200 -h -w100 -L -a0,1,2,3 F:\diskspd.dat >> SIOWS2012R203_Eiscsi_145_noh_write100.txt

    diskspd -c45g -b8K -t16 -o32 -r -d7200 -h -S -w0 -L -a0,1,2,3 F:\diskspd.dat >> SIOWS2012R203_Eiscsi_145_noSh_test_write000.txt

    diskspd -c45g -b8K -t16 -o32 -r -d7200 -h -S -w50 -L -a0,1,2,3 F:\diskspd.dat >> SIOWS2012R203_Eiscsi_145_noSh_write050.txt

    diskspd -c45g -b8K -t16 -o32 -r -d7200 -h -S -w100 -L -a0,1,2,3 F:\diskspd.dat >> SIOWS2012R203_Eiscsi_145_noSh_write100.txt

    The following is the output from the above workload command.
    Microsoft Diskspd sample output
    Microsoft Diskspd sample output part 2
    Microsoft Diskspd sample output part 3

    Note that as with any benchmark, workload test or simulation your results will vary. In the above the server, storage and I/O system were not tuned as the focus was on working with the tool, determining its capabilities. Thus do not focus on the performance results per say, rather what you can do with Diskspd as a tool to try different things. Btw, fwiw, in the above example in addition to using an iSCSI target, the Windows 2012 R2 server was a guest on a VMware ESXi 5.5 system.

    Reporting including CPU usage (you can’t do server and storage I/O without CPU) along with IOP’s (activity), bandwidth (throughout or amount of data being moved), per thread and total results along with optional reporting. While a GUI would be nice particular for beginners, I’m used to setting up scripts for different workloads so having an extensive options for setting up different workloads is welcome. Being associated with a specific OS (e.g. Windows) the CPU affinity and buffer management controls will be handy for some projects.

    Diskspd has the flexibility to use different storage interfaces and types of storage including files or partitions should be taken for granted, however with some tools don’t take things for granted. I like the flexibility to easily specify various IO sizes including large 1MByte, 10MByte, 20MByte, 100MByte and 500MByte to simulate application workloads that do large sequential (or random) activity. I tried some IO sizes (e.g. specified by -b parameter larger than 500MB however, I received various errors including "Could not allocate a buffer bytes for target" which means that Diskspd can do IO sizes smaller than that. While not able to do IO sizes larger than 500MB, this is actually impressive. Several other tools I have used or with have IO size limits down around 10MByte which makes it difficult for creating workloads that do large IOP’s (note this is the IOP size, not the number of IOP’s).

    Oh, something else that should be obvious however will state it, Diskspd is free unlike some industry de-facto standard tools or workload generators that need a fee to get and use.

    Where Diskspd could be improved (Cons)

    For some users a GUI or configuration wizard would make the tool easier to get started with, on the other hand (oth), I tend to use the command capabilities of tools. Would also be nice to specify ranges as part of a single command such as stepping through an IO size range (e.g. 4K, 8K, 16K, 1MB, 10MB) as well as read write percentages along with varying random sequential mixes. Granted this can easily be done by having a series of commands, however I have become spoiled by using other tools such as vdbench.

    Summary

    Server and storage I/O performance toolbox

    Overall I like Diskspd and have added it to my Server Storage I/O workload and benchmark tool-box

    Keep in mind that the best benchmark or workload generation technology tool will be your own application(s) configured to run as close as possible to production activity levels.

    However when that is not possible, the an alternative is to use tools that have the flexibility to be configured as close as possible to your application(s) workload characteristics. This means that the focus should not be as much on the tool, as opposed to how flexible is a tool to work for you, granted the tool needs to be robust.

    Having said that, Microsoft Diskspd is a good and extensible tool for benchmarking, simulation, validation and comparisons, however it will only be as good as the parameters and configuration you set it up to use.

    Check out Microsoft Diskspd and add it to your benchmark and server storage I/O tool-box like I have done.

    The best server and storage I/O (input/output operation) is the one that you do not have to do, the second best is the one with the least impact.

    server storage I/O locality of reference

    This is where the idea of locality of reference (e.g. how close is the data to where your application is running) comes into play which is implemented via tiered memory, storage and caching shown in the figure above.

    Cloud virtual software defined storage I/O

    Server storage I/O performance applies to cloud, virtual, software defined and legacy environments

    What this has to do with server storage I/O (and networking) performance benchmarking is keeping the idea of locality of reference, context and the application workload in perspective regardless of if cloud, virtual, software defined or legacy physical environments.

    I/O, I/O how well do you know good bad ugly server storage I/O iops?

    How well do you know good bad ugly I/O iops?

    server storage i/o iops activity data infrastructure trends

    Updated 2/10/2018

    There are many different types of server storage I/O iops associated with various environments, applications and workloads. Some I/Os activity are iops, others are transactions per second (TPS), files or messages per time (hour, minute, second), gets, puts or other operations. The best IO is one you do not have to do.

    What about all the cloud, virtual, software defined and legacy based application that still need to do I/O?

    If no IO operation is the best IO, then the second best IO is the one that can be done as close to the application and processor as possible with the best locality of reference.

    Also keep in mind that aggregation (e.g. consolidation) can cause aggravation (server storage I/O performance bottlenecks).

    aggregation causes aggravation
    Example of aggregation (consolidation) causing aggravation (server storage i/o blender bottlenecks)

    And the third best?

    It’s the one that can be done in less time or at least cost or effect to the requesting application, which means moving further down the memory and storage stack.

    solving server storage i/o blender and other bottlenecks
    Leveraging flash SSD and cache technologies to find and fix server storage I/O bottlenecks

    On the other hand, any IOP regardless of if for block, file or object storage that involves some context is better than those without, particular involving metrics that matter (here, here and here [webinar] )

    Server Storage I/O optimization and effectiveness

    The problem with IO’s is that they are a basic operations to get data into and out of a computer or processor, so there’s no way to avoid all of them, unless you have a very large budget. Even if you have a large budget that can afford an all flash SSD solution, you may still meet bottlenecks or other barriers.

    IO’s require CPU or processor time and memory to set up and then process the results as well as IO and networking resources to move data too their destination or retrieve them from where they are stored. While IO’s cannot be eliminated, their impact can be greatly improved or optimized by, among other techniques, doing fewer of them via caching and by grouping reads or writes (pre-fetch, write-behind).

    server storage I/O STI and SUT

    Think of it this way: Instead of going on multiple errands, sometimes you can group multiple destinations together making for a shorter, more efficient trip. However, that optimization may also mean your drive will take longer. So, sometimes it makes sense to go on a couple of quick, short, low-latency trips instead of one larger one that takes half a day even as it accomplishes many tasks. Of course, how far you have to go on those trips (i.e., their locality) makes a difference about how many you can do in a given amount of time.

    Locality of reference (or proximity)

    What is locality of reference?

    This refers to how close (i.e., its place) data exists to where it is needed (being referenced) for use. For example, the best locality of reference in a computer would be registers in the processor core, ready to be acted on immediately. This would be followed by levels 1, 2, and 3 (L1, L2, and L3) onboard caches, followed by main memory, or DRAM. After that comes solid-state memory typically NAND flash either on PCIe cards or accessible on a direct attached storage (DAS), SAN, or NAS device. 

    server storage I/O locality of reference

    Even though a PCIe NAND flash card is close to the processor, there still remains the overhead of traversing the PCIe bus and associated drivers. To help offset that impact, PCIe cards use DRAM as cache or buffers for data along with meta or control information to further optimize and improve locality of reference. In other words, this information is used to help with cache hits, cache use, and cache effectiveness vs. simply boosting cache use.

    SSD to the rescue?

    What can you do the cut the impact of IO’s?

    There are many steps one can take, starting with establishing baseline performance and availability metrics.

    The metrics that matter include IOP’s, latency, bandwidth, and availability. Then, leverage metrics to gain insight into your application’s performance.

    Understand that IO’s are a fact of applications doing work (storing, retrieving, managing data) no matter whether systems are virtual, physical, or running up in the cloud. But it’s important to understand just what a bad IO is, along with its impact on performance. Try to identify those that are bad, and then find and fix the problem, either with software, application, or database changes. Perhaps you need to throw more software caching tools, hypervisors, or hardware at the problem. Hardware may include faster processors with more DRAM and faster internal busses.

    Leveraging local PCIe flash SSD cards for caching or as targets is another option.

    You may want to use storage systems or appliances that rely on intelligent caching and storage optimization capabilities to help with performance, availability, and capacity.

    Where to gain insight into your server storage I/O environment

    There are many tools that you can be used to gain insight into your server storage I/O environment across cloud, virtual, software defined and legacy as well as from different layers (e.g. applications, database, file systems, operating systems, hypervisors, server, storage, I/O networking). Many applications along with databases have either built-in or optional tools from their provider, third-party, or via other sources that can give information about work activity being done. Likewise there are tools to dig down deeper into the various data information infrastructure to see what is happening at the various layers as shown in the following figures.

    application storage I/O performance
    Gaining application and operating system level performance insight via different tools

    windows and linux storage I/O performance
    Insight and awareness via operating system tools on Windows and Linux

    In the above example, Spotlight on Windows (SoW) which you can download for free from Dell here along with Ubuntu utilities are shown, You could also use other tools to look at server storage I/O performance including Windows Perfmon among others.

    vmware server storage I/O
    Hypervisor performance using VMware ESXi / vsphere built-in tools

    vmware server storage I/O performance
    Using Visual ESXtop to dig deeper into virtual server storage I/O performance

    vmware server storage i/o cache
    Gaining insight into virtual server storage I/O cache performance

    Wrap up and summary

    There are many approaches to address (e.g. find and fix) vs. simply move or mask data center and server storage I/O bottlenecks. Having insight and awareness into how your environment along with applications is important to know to focus resources. Also keep in mind that a bit of flash SSD or DRAM cache in the applicable place can go along way while a lot of cache will also cost you cash. Even if you cant eliminate I/Os, look for ways to decrease their impact on your applications and systems.

    Green and Virtual IT Data Center Primer

    Green and Virtual Data Center Primer

    Moving beyond Green Hype and Green washing

    Green IT is about enabling efficient, effective and productive information services delivery. There is a growing green gap between green hype messaging or green washing and IT pain point issues including limits on availability or rising costs of power, cooling, floor-space as well as e-waste and environmental health and safety (PCFE). To close the gap will involve addressing green messaging and rhetoric closer to where IT organizations pain points are and where budget dollars exists that can address PCFE and other green related issues as a by-product. The green gap will also be narrowed as awareness of broader green related topics coincide with IT data center pain points, in other words, alignment of messaging with IT issues that have or will have budget dollars allocated towards them to sustain business and economic growth via IT resource usage efficiency. Read more here.

    There are many aspects to "Green" Information Technology including servers, storage, networks and associated management tools and techniques. The reasons and focus of "Green IT" including "Green Data Storage ", "Green Computing" and related focus areas are varied to discuss diverse needs, issues and requirements including among others:

    • Power, Cooling, Floor-space, Environmental (PCFE) related issues or constraints
    • Reduction of carbon dioxide (CO2) emissions and other green house gases (GHGs)
    • Business growth and economic sustain in an environmental friendly manner
    • Proper disposal or recycling of environmental harmful retired technology components
    • Reduction or better efficiency of electrical power consumption used for IT equipment
    • Cost avoidance or savings from lower energy fees and cooling costs
    • Support data center and application consolidation to cut cost and management
    • Enable growth and enhancements to application service level objectives
    • Maximize the usage of available power and cooling resources available in your region
    • Compliance with local or federal government mandates and regulations
    • Economic sustain and ability to support business growth and service improvements
    • General environmental awareness and stewardship to save and protect the earth

    While much of the IT industry focuses on CO2 emissions footprints, data management software and electrical power consumption, cooling and ventilation of IT data centers is an area of focus associated with "Green IT" as well as a means to discuss more effective use of electrical energy that can yield rapid results for many environments. Large tier-1 vendors including HP and IBM among others who have an IT and data center wide focus have services designed to do quick assessments as well as detailed analysis and re-organization of IT data center physical facilities to improve air flow and power consumption for more effective cooling of IT technologies including servers, storage, networks and other equipment.

    Similar to your own residence, basic steps to improve your cooling effectiveness can lead to use of less energy to cut your budget impact, or, enable you to do more with what you already have with your cooling capacity to support growth, acquisitions and or consolidation initiatives. Vendors are also looking at means and alternatives for cooling IT equipment ranging from computer assisted computational fluid dynamics (CFD) software analysis of data center cooling and ventilation to refrigerated cooling racks some leveraging water or inert liquid cooling.

    Various metrics exists and others are evolving for measuring, estimating, reporting, analyzing and discussing IT Data Center infrastructure resource topics including servers, storage, networks, facilities and associated software management tools from a power, cooling and green environmental standpoint. The importance of metrics is to focus on the larger impact of a piece of IT equipment that includes its cost and energy consumption that factors in cooling and other hosting or site environmental costs. Naturally energy costs and CO2 (carbon offsets) will vary by geography and region along with type of electrical power being used (Coal, Natural Gas, Nuclear, Wind, Thermo, Solar, etc) and other factors that should be kept in perspective as part of the big picture.

    Consequently your view and needs or interests around "Green" IT may be from an electrical power conservation perspective to maximize your power consumption or to adapt to a given power footprint or ceiling. Your focus around "Green" Data Centers and Green Storage may be from a carbon savings standpoint or proper disposition of old and retired IT equipment or from a data center cooling standpoint. Another area of focus may be that you are looking to cut your data footprint to align with your power, cooling and green footprint while enhancing application and data service delivery to your customers.

    Green and Virtual IT Data Center Links

    Moving beyond Green Hype and Green washing

    Green hype and green washing may be on the endangered species list and going away, however, green IT for servers, storage, networks, facilities as well as related software and management techniques that address energy efficiency including power and cooling along with e-waste, environmental health and safety related issues are topics that wont be going away anytime soon.

    There is a growing green gap between green hype messaging or green washing and IT pain point issues including limits on availability or rising costs of power, cooling, floor-space as well as e-waste and environmental health and safety (PCFE).

    To close the gap will involve addressing green messaging and rhetoric closer to where IT organizations pain points are and where budget dollars exists that can address PCFE and other green related issues as a by-product. The green gap will also be narrowed as awareness of broader green related topics coincide with IT data center pain points, in other words, alignment of messaging with IT issues that have or will have budget dollars allocated towards them to sustain business and economic growth via IT resource usage efficiency.

    Green and Virtual Metrics

    Chapter 5 "Measurement, Metrics, and Management of IT Resources" in the book "The Green and Virtual Data Center" (CRC Press) takes a look at the importance of being able to measure and monitor to enable effective management and utilization of IT resources across servers, storage, I/O networks, software, hardware and facilities.

    There are many different points of interest for collecting metrics in an IT data center for servers, storage, networking and facilities along with various points of interest or perspectives. Data center personal have varied interest from a facilities to a resource (server, storage, networking) usage and effectiveness perspective for normal use as well as planning purposes or comparison when evaluating new technology. Vendors have different uses for metrics during R&D, Q/A testing and marketing or sales campaigns as well as on-going service and support. Industry trade groups including 80 Plus, SNIA and the green grid along with government groups including the EPA Energy Star are working to define and establish applicable metrics pertinent for Green and Virtual data centers.

    Activity / Watt Amount of work accomplished per unit of energy consumed. This could be IOPS, Transactions or Bandwidth per watt. Indicator how much work and how efficient energy is being used to accomplish useful work. This metric applies to active workloads or actively used and frequently accessed storage and data. Examples would be IOPS per watt, Bandwidth per watt, Transactions per watt, Users or streams per watt. Activity per watt should also be used in conjunction with another metric such as how much capacity is supported per watt and total watts consumed for a representative picture.

    IOPS / Watt

    Number of I/O operations (or transactions) / energy (watts)

    Indicator of how effectively energy is being used to perform a given amount of work. The work could be I/Os, transactions, throughput or other indicator of application activity. For example SPC-1 / Watt, SPEC / Watt, TPC / Watt, transaction / watt,  IOP / Watt.

    Bandwidth / Watt GBPS or TBPS or PBPS / Watt Amount of data transferred or moved per second and energy used. Often confused with Capacity per watt This indicates how much data is moved or accessed per second or time interval per unit of energy consumed. This is often confused with capacity per watt given that both bandwidth and capacity reference GByte, TByte, PByte.

    Capacity / Watt

    GB or TB or PB (storage capacity space / watt

    Indicator of how much capacity (space) or bandwidth supported in a given configuration or footprint per watt of energy. For inactive data or off-line and archive data, capacity per watt can be an effective measurement gauge however for active workloads and applications activity per watt also needs to be looked at to get a representative indicator of how energy is being used

    Mhz / Watt

    Processor performance / energy (watts)

    Indicator of how effectively energy is being used by a CPU or processor.

    Carbon Credit

    Various power, cooling, floor space and green storage or IT  related metrics

    Metrics include Data center Efficiency (DCiE) via the greengrid which is the indicator ratio of a IT data center energy efficiency defined as IT equipment (servers, disk and tape storage, networking switches, routers, printers, etc) / Total facility power x 100 (for percentage). For example, if the sum of all IT equipment energy usage resulted in 1,500 kilowatt hours (kWh) per month yet the total facility power including UPS, energy switching, power conversation and filtering, cooling and associated infrastructure costs as well as IT equipment resulting in 3,500 kWh, the DCiE would be (1,500 / 3,500) x 100 = 43%. DCiE can be used as a ratio for example to show in the above scenario that IT equipment accounts for about 43% of energy consumed by the data center with in this scenario 57% of electrical energy being consumed by cooling, conversion and conditioning or lighting.

    Power usage effectiveness (PUE) is the indicator ratio of total energy being consumed by the data center to energy being used to operate IT equipment. PUE is defined as total facility power / IT equipment energy consumption. Using the above scenario PUE = 2.333 (3,500 / 1,500) which means that a server requiring 100 watts of power would actually require (2.333 * 100) 233.3 watts of energy that includes both direct power and cooling costs. Similarly a storage system that required 1,500 kWh of energy to power would require (1,500*2.333) 3,499.5 kWh of electrical power including cooling.

    Another metric that has the potential to have meaning is Data center Performance Efficiency (DCPE) that takes into consideration how much useful and effective work is performed by the IT equipment and data center per energy consumed. DCPE is defined as useful work / total facility power with an example being some number of transactions processed using servers, networks and storage divided by energy for the data center to power and cool the equipment. An relatively easy and straightforward implementation of DCPE is an IOPs per watt measurement that looks at how many IOPs can be performed (regardless of size or type such as reads or writes) per unit of energy in this case watts.

    DCPE = Useful work / Total facility power, for example IOPS per watt of energy used

    DCiE = IT equipment energy / Total facility power = 1 / PUE

    PUE = Total facility energy / IT equipment energy

    IOPS per Watt = Number of IOPs (or bandwidth) / energy used by the storage system

    The importance of these numbers and metrics is to focus on the larger impact of a piece of IT equipment that includes its cost and energy consumption that factors in cooling and other hosting or site environmental costs. Naturally energy costs and CO2 (carbon offsets) will vary by geography and region along with type of electrical power being used (Coal, Natural Gas, Nuclear, Wind, Thermo, Solar, etc) and other factors that should be kept in perspective as part of the big picture. Learn more in Chapter 5 "Measurement, Metrics, and Management of IT Resources" in the book "The Green and Virtual Data Center" (CRC) and in the book Cloud and Virtual Data Storage Networking (CRC).
