That doesn’t necessarily mean your SAN is slow though. The key to a successful relationship is … actually, I have no idea what it is, but it’s on the same keyring as the car your girlfriend wants. Knowing I’m getting so many IOPS or throughput does me absolutely no good personally unless I can confirm or deny that it’s meeting the theoretical expectations. Do you have any thoughts or guidelines on how to compare / contrast the results from both methods? The screen cap above shows 4GB but the text says use 32GB. 9 Runs of 4Gb in Crystal Mark, each San Controller has 16Gb cache so that may be affecting results. Yep, make sure to read the post carefully – the post is up to date, while the screenshots may be from older versions. There are multiple download links – you want CRYSTALDISKMARK, not CrystalDiskInfo. I personally do that because I’m a numbers/math person and feel that’s the only way to make sense of the output using these sorts of tools. CrystalDiskMark is a freeware utility for measuring disk performance. For solid state drives, the difference between sequential and random operations isn’t always as dramatic, but it can still be 2-3x. In this subreddit, we celebrate and promote the ultimate gaming and working platform. I think they look OK but not 100%sure. If it runs 5 loops for test, the test result will demonstrate the best score or average of 5 loops? I’ve used your SQLIO tutorial to test my servers / SAN before. I am running SQL Server 2008 R2 Enterprise x64 on Server 2008 R2 Enterprise (this is a cluster). I can’t seem to find what the D was for in version 3. CrystalDiskMark Portable 8.0.0a Deutsch: "CrystalDiskMark Portable" ist ein Gratis-Tool, das nicht installiert werden muss, um die Lese- und Schreibgeschwindigkeit Ihrer Festplatten zu testen. Will it impact my server? Based on Microsoft's MIT-licensed Diskspd tool, this graphical benchmark is commonly used for testing the performance of solid-state storage. We finally convinced them to separate them and wow all is good. Default value is 5. If i run crystal diskmark on production server? ———————————————————————– CrystalDiskMark 3.0.3 x64 (C) 2007-2013 hiyohiyo Crystal Dew World : http://crystalmark.info/ ———————————————————————– * MB/s = 1,000,000 byte/s [SATA/300 = 300,000,000 byte/s], Sequential Read : 1979.379 MB/s Sequential Write : 238.530 MB/s Random Read 512KB : 1878.255 MB/s Random Write 512KB : 182.255 MB/s Random Read 4KB (QD=1) : 71.724 MB/s [ 17510.8 IOPS] Random Write 4KB (QD=1) : 6.002 MB/s [ 1465.4 IOPS] Random Read 4KB (QD=32) : 385.019 MB/s [ 93998.8 IOPS] Random Write 4KB (QD=32) : 29.038 MB/s [ 7089.5 IOPS], Test : 4000 MB [X: 0.1% (0.1/99.9 GB)] (x9) Date : 2014/11/02 16:39:33 OS : Windows Server 2012 R2 Server Standard (full installation) [6.3 Build 9600] (x64). There are lots of people who said that CrystalDiskMark’s 512K test seems kind of redundant to them. Hi, Bryan. Mike – that’s interesting, but I think the number of variables (VM, CSV cache, tiering) makes things a little unpredictable. 1GiB – the test file size. I will use version 3. CrystalDiskMark is a Benchmarking application like RAM Disk, HWMonitor, and PCMark from Hiyohiyo (Crystal Dew World). The link to CrystalDiskMark doesn’t seem to have a valid program. As know some of the newer SAN’s detect zero’s and don’t even get to the disk/ssd, at this point we are pretty much testing Controllers. Here’s local ephemeral NVMe storage in … Tim – I’m not quite sure what you’re asking – can you rephrase it? For support questions about CrystalDiskMark, your best bet is to contact the authors. I spent nearly three days reading up on every piece of literature I could find on my hardware before I even started to run tests because the tests mean nothing without some sort of expectations to match the results up against. Mike – for Q&A, head on over to https://dba.stackexchange.com. SEQ Q1M Q8T1 – lots of long, sequential operations. :(, Ok dumb question just saw your video, you referenced downloading the portable version. Smaller test file sizes may look fast but don’t really reflect how a large database will work. Usually I find that during the first round of storage tests, it’s not performing well period – and it doesn’t make sense to bring SQL Server into the game just yet. Instead, let’s get seat-of-the-pants numbers for your storage. Unfortunately, personalized diagnostics of a SAN is kinda beyond the scope of something we can do in a blog comment. It works by reading and writing through the filesystem in a volume-dependent way. Features and highlights. Each raid-5 raid group is presented to the SVC as a lun. If we have exactly one database, and we’re not doing t-log backups as we’re loading, then it’s possible to get close. You – and by you I mean we – don’t need a turbo.”, As soon as she accelerated onto a highway on-ramp, felt the power surge, and heard the turbo whistle, that was the end of that. and a part of USB, RAID and NVMe. You want the file to be big enough to know you aren’t just hitting the cache, but rather are hitting the disks. A few years ago, Erika and I went to the VW dealership to trade in her old Jetta and get a new one. The LUN’s are shared between Exchange / SQL / F&P and Term Services so I’m thinking that the SAN gets saturated from time to time so we are seeing really IO in SQL server – like 25-35ms and this is causing lots of cxpacket waits and lock / latch errors – am I on the right track to we think? CrystalDiskMark is benchmark software that measures the transfer speed of media data storage drive such as HD, SSD, USB memory, SD card and NAS. And 119.3 (as reported by lsblk) = 119.3 x 1073700000 = 128092410000.So when you buy that next drive, read the fine print on the back and check whether they use the "1000" bytes per KiloByte or the "1024" bytes per Kibibyte standard. I’d also check out my Building the Fastest SQL Servers video from TechEd. This is a great little tool! John T – yeah, that’s fairly typical of what I see with that type of storage gear. Also, CSV cache has been increased from 0Gb (default) to 16 Gb. It takes knowledge and time, and you only have one of those. Can you provide some guidelines on testing with the new version in terms of the Queues and threads setting? Any idea why my C drive would have this result.. ———————————————————————– CrystalDiskMark 6.0.2 (C) 2007-2018 hiyohiyo ———————————————————————– Sequential Read (Q= 32,T= 1) : 190.420 MB/s Sequential Write (Q= 32,T= 1) : 31.929 MB/s Random Read 4KiB (Q= 8,T= 8) : 2.698 MB/s [ 658.7 IOPS] Random Write 4KiB (Q= 8,T= 8) : 0.583 MB/s [ 142.3 IOPS] Random Read 4KiB (Q= 32,T= 1) : 2.869 MB/s [ 700.4 IOPS] Random Write 4KiB (Q= 32,T= 1) : 0.425 MB/s [ 103.8 IOPS] Random Read 4KiB (Q= 1,T= 1) : 0.200 MB/s [ 48.8 IOPS] Random Write 4KiB (Q= 1,T= 1) : 0.149 MB/s [ 36.4 IOPS], Test : 1024 MiB [C: 30.1% (18.0/60.0 GiB)] (x5) [Interval=5 sec] Date : 2019/06/11 22:38:04 OS : Windows Server 2003 SP2 [5.2 Build 3790] (x86), And my D drive would have this result??? CrystalDiskMark is designed to quickly test the performance of your hard drives. This is from an e-mail that was sent to me. The test drive is a Dynamic .vhdx of 100Gb dedicated for the test. 1 – the number of test passes you want to run. Thanks! Often I find that the OS’s drives perform even better because we just haven’t configured and tuned our storage. The Windows version was created by Crystal Dew World. (Of course a write test that writes all zeroes again into the file will undo the randomization of data content and probably revert to unrealistically good results.). If you want a fast seat-of-the-pants guess, do 1, but keep in mind it can be wildly variant between passes if something else happens to be going on in the SAN. I’ve seen much higher with Compellent gear, so I’d say it’s probably time to start troubleshooting. It’s hard to compare apples to apples with complete strangers in the storage world. […] tests are incredibly low, but that’s likely due to the fact that they’re attempting to read and write tiny 4KB files all around the drive—a technique that mechanical hard drives don’t do very well with, […]. OpenLibSys.org Obsolete Projects CrystalDiskMarkはHDD、SSD、USBメモリ、SDカード、NASなど各種記憶メディアの読み書き速度を計測する際のデファクトスタンダードともいえるツールだ。一般のユーザーに使われているだけではなく、ベンダーのWebサイトや雑誌記事などでも頻繁に目にすることができる。 Nimble Storage CS300 Seq Q32T1 – 247.3 – 246,5 4K Q32T1 – 182.0 – 172.5 Seq – 107.0 – 106.1 4K 5.871 – 5.765. I have an 11 year old Turbo Jetta. CrystalDiskMark is probably ranked at the top, but there are others too. All Rights Reserved. The VLF thing has less to do with disk fragmentation and more to do with the way SQL Server manages virtual log files. I just ran this on the data drive of a new win2k8r2, SQL 2008 r2 OLTP test cluster. When you compare those, what’s the fastest number that you’re getting in CrystalDiskMark, and does that correspond to a cable type that Kendra shows on the poster? Select Number of Test Runs, Test Size and Test Drive. She couldn’t hear me because I was in the back seat and she was negotiating price with the sales guy. CrystalDiskMark Main Menu Main Menu File Copy Copy the result of benchmark to the clipboard. Hi guys, I am a rather novice in SQL matters but have been Reading quite a lot of your articles and find it very interesting and helpful. got a new EMC SAN moved all database storage to it last month Seeing some disk queue backups on our OLTP server which is a 2008 Act/passive cluster. Whats the best path forward – moving to SSD shelf? Go to the CrystalDiskMark download page, but PAY CLOSE ATTENTION. CrystalDiskMark ist das derzeit beliebteste Programm, um die Schreib- und Lesegeschwindigkeit einer Festplatte oder USB-Sticks zu messen. So in this tutorial, I will show you how to install Sequential reads were 50-100MB/s faster. Hi Brent, we are planning to move our SQL server (VM) from our current vendor to Azure VM. You can also subscribe without commenting. If you’re using iscsi, you may only see a maximum of 165MB/s or so due to the limits of 1gig ethernet. You want to test where your data, log, and TempDB files live, and for fun, also test the C drive and your desktop or laptop for comparison. Thoughts? I wouldn’t directly draw a line between too many VLFs and slow write stalls. Die Freeware CrystalDiskMark 7.0.0h analysiert Ihre verwendeten Festplatten, USB-Speichern und SSDs und stellt anschließend die ermittelten Schreib- und Lesegeschwindigkeiten dar. ... For a faster drive you can use maybe 3/5 passes and 100/500MB test size to get a more representative score. We had a client who had the same setup, I would be worried if there is any sharing of the SAN with Exchange. I really thought you were going to post some numbers here but it turns out you’re just a tease :]. How to use CrystalDiskMark. Something worth mentioning is that using CrystalDiskMark in this manner only tests the maximum throughput of your SAN. I use CrystalDiskMark as a fast “easy button” for people to do quick throughput testing, and then if time allows, I use SQLIO to do much more in-depth testing. Is that because we want the write behavior of the TLog file to be as close to the number reported by crystal disk mark as “Sequential” writes? In my experience, the main numbers you want to look at / optimize for are sequential reads for table/index scans, and something in between the 512K and 4K random reads for the rest of an OLTP workload. When I restore DB on our current production, it takes around 2 minutes, but on Azure VM, it takes around 15 minutes. Do you have another link location for this software? Rick – howdy sir! CrystalDiskMark user interface contains three options on the top, The first option is to choose the number of passes for each test, it ranges from 1 to 9 with the default value at 5. I make Microsoft SQL Server go faster. Default value is 1GiB. The third option is the drive selection drop-down menu. I am using a NetApp for the sql server data files and a raid 10 for the OS. CrystalDiskMarkの使い方 インストールが完了したら早速CrystalDiskMarkを起動してストレージのスコアを測っていきましょう。 スコアの測定方法 まずは核心となるスコアの計測方法からご紹介。今回はSDカードの転送速度を計測しますので、まずはパソコンにSDカードリーダーを挿し込みます。 Sounds like something you’d want to start building, then. Thanks. This may be one of the most profound thoughts I have ever read. (MB/s). This metric is often limited by how the computer is connected to the storage. Required fields are marked *. I do not like much this test tool CrystalDiskMark 6.0.2 x64 because it is next to impossible to analyze the results logically, systematically! Now it has all the way up to 32 GB. The Test Server is HyperV 2012R2 (running on a 3 Node HyperV 2012 R2 cluster). How to start Benchmark. I use CrystalDiskMark quite a bit. CrystalDiskMark 4-6 uses Microsoft DiskSpd (The MIT License). Click “All” button (or others button) to start Benchmark. CrystalDiskMark is a disk benchmark software.It measure sequential reads/writes speed,measure random 512KB, 4KB, 4KB (Queue Depth=32) … CrystalDiskMark 8.0.0a Deutsch: CrystalDiskMark testet die Lese- und Schreibgeschwindigkeit Ihrer Festplatten anhand dreier Testverfahren. Benutzer können die Anzahl der gewünschten Tests, die Größe (in … I was seeing preposterously high results in a VMWare Player virtualized environment with SQLIO, presumably because of the data file being all zeroes. When I run CrystalDiskMark on our current production SQL server (Yes, I did it in production, but I couldn’t resist :)), I get significantly higher read/write numbers than Azure VM. If your server boots from a mirrored pair of local drives, and stores its SQL Server data somewhere else (like on a larger array or on a SAN), then test the local mirrored pair too. If I’m not mistaken you also get a non-zeroed data file. Brent, thanks for the helpful articles I really appreciate them. You Think it would be wise to move all SQL files to the G: drive instead (the easy solution) to get better performance from SQL Server? We took a test drive of the base model, and then the sales guy asked, “Do you wanna also test drive the 1.8L Turbo version?”, Me: “You were just saying how this one is so much peppier than yours. SQL Server stores stuff on disk in 8K pages, and zooming out a little, groups of 8 8KB pages (64K extents). Can we use slow average write stalls (calculated from info in sys.dm_io_virtual_file_stats) as a symptom of too-many-VLFs? Is there any correlation between them? ), Hello…can u please take a look at my results Seq –> Read :162.2 Mb/s Write :153.3 Mb/s 512K –> Read :43.01 Mb/s Write :117 Mb/s 4K –> Read :0.718 Mb/s Write :4.458 Mb/s 4K QD32 –> Read : 13.42 Write :16.58 Seq –> Read :162.2 Mb/s Write :153.3 Mb/s These are on a brand new EQ 4100x…2 x1 Gb iSCSI…nothing is connected except the testing volumes Dell told me that the SAN is running just fine but i just admit that this is the best 22 HDDs -RAID 50 can deliver… I tried to point them to these poor results from CD or Hdtune but i hit a brick wall that they are not validated and only IOmeter is good… Take a note that when Iometer runs on 64 threads i saturated the network bandwidth but when i reduced the threads to 1 i get around 30 Mb/s….to me it seems bizarre. Bryan – sure, what do you think needs to be changed? Users can decide the number of tests they want to do, the size (in megabytes) of the test, and the drive they want to test. Is it normally the case with Azure Premium SSDs? Raj – unfortunately, I can’t do free personal consulting in the comments. Then specify that file in your SQLIO read test to get a more accurate result. Crystaldiskmark is good but diskspd is much better. This is somewhat akin to an active OLTP server, or a TempDB drive. It’ll look like this: Across the top, the first three dropdowns should be: After making your choices, click the All button. We no longer offer the bandwidth reference poster. And for the question, “Does this matter in VMs?” I would say it does more, because that is another layer where you could have an ill advised setting holding you back. A portable version without this can be found here: http://sourceforge.jp/projects/crystaldiskmark/downloads/46482/CrystalDiskMark3_0_3b.zip. See screenshots, read the latest customer reviews, and compare ratings for CrystalDiskMark. Run it on an idle server or desktop first (not your live SQL Server, because it’ll slow things down while it runs.) We have an IBM DS5300 with 300GB 15k disks. Important Notice Both CrystalDiskInfo and CrystalDiskMark are open source software personally developed by me. Download and launch the utility; Chose a drive with the dropdown on the upper right; Click "All" Let the tests run and watch the various speed fields populate; After multiple runs, CrystalDiskMark will take best reading rather than the average; Screenshot Thanks for the quick response. In my experience, the main numbers you want to look at / optimize for are sequential reads for table/index scans, and something in between the 512K and 4K random reads for the rest of an OLTP workload. Outside this bracket of acceptable values, you would have values that indicate problems with your hardware device. It makes my wife’s Honda Accord seem like a golf cart or a BlueArc SAN. Here is what out storage admin has to say about the configuration. I went through the bandwidth reference poster and I still dont understand the results. Ascend to... the PC Master Race. Hard to compare exactly but these are much better results. Ron – unfortunately we haven’t used v4 yet. CrystalDiskMark 3.0.1 A way to uninstall CrystalDiskMark 3.0.1 from your computer This info is about CrystalDiskMark 3.0.1 for Windows. It gives you insight into what the disk performance is like for that guest with its given storage configuration. Since I’m tied into an EMC, I do use PowerPath as well. VirtualChecker A Virtualization Features Status Checker. Click “All” button (or others button) to start Benchmark. Is the perfmon counter “Disk Read Bytes/sec” and “Disk Write Bytes/sec” the same? Ascend to a level that respects your eyes, your wallet, your mind, and your heart. Now, whether or not your virtual disk configuration is what’s slowing you down is a different story– you’d need to investigate to confirm how much of a difference that was making. If you’re using MPIO and have lots of fast disks, you can still serve a very large number of IOPs. I have other Xen servers that are comparable and have these results… ———————————————————————– CrystalDiskMark 6.0.2 (C) 2007-2018 hiyohiyo ———————————————————————– Sequential Read (Q= 32,T= 1) : 532.111 MB/s Sequential Write (Q= 32,T= 1) : 30.357 MB/s Random Read 4KiB (Q= 8,T= 8) : 11.131 MB/s [ 2717.5 IOPS] Random Write 4KiB (Q= 8,T= 8) : 2.651 MB/s [ 647.2 IOPS] Random Read 4KiB (Q= 32,T= 1) : 11.249 MB/s [ 2746.3 IOPS] Random Write 4KiB (Q= 32,T= 1) : 2.596 MB/s [ 633.8 IOPS] Random Read 4KiB (Q= 1,T= 1) : 1.816 MB/s [ 443.4 IOPS] Random Write 4KiB (Q= 1,T= 1) : 0.566 MB/s [ 138.2 IOPS], Test : 1024 MiB [D: 27.8% (19.4/70.0 GiB)] (x5) [Interval=5 sec] Date : 2019/06/11 22:41:45 OS : Windows Server 2003 R2 Enterprise Edition SP2 [5.2 Build 3790] (x86), ———————————————————————– CrystalDiskMark 6.0.2 (C) 2007-2018 hiyohiyo ———————————————————————– Sequential Read (Q= 32,T= 1) : 316.975 MB/s Sequential Write (Q= 32,T= 1) : 26.218 MB/s Random Read 4KiB (Q= 8,T= 8) : 10.244 MB/s [ 2501.0 IOPS] Random Write 4KiB (Q= 8,T= 8) : 1.919 MB/s [ 468.5 IOPS] Random Read 4KiB (Q= 32,T= 1) : 5.007 MB/s [ 1222.4 IOPS] Random Write 4KiB (Q= 32,T= 1) : 1.335 MB/s [ 325.9 IOPS] Random Read 4KiB (Q= 1,T= 1) : 1.155 MB/s [ 282.0 IOPS] Random Write 4KiB (Q= 1,T= 1) : 0.383 MB/s [ 93.5 IOPS], Test : 1024 MiB [D: 27.8% (19.4/70.0 GiB)] (x5) [Interval=5 sec] Date : 2019/06/11 22:51:11 OS : Windows Server 2003 R2 Enterprise Edition SP2 [5.2 Build 3790] (x86).

Das.. It has a simple and basic user interface, and most importantly, it is free to download. I use CrystalDiskMark quite a bit. Number of Test 1~9. For vmware there is a beta tool “IO Analyzer” that people are posting all kinds of results here: http://communities.vmware.com/message/1780088#1780088. See screenshots, read the latest customer reviews, and compare ratings for CrystalDiskMark. Customer has all SQL databases and Log file placed on the E: drive, which is the same logical drive as C (which i suspect is on SAN storage, and most likely shared with numeruous other applications. Michael – well, no, not really. … For whatever reason, I/O Operations Per Second (IOPS) is not showed at all. Maybe they have a point but the response shouldn’t be to shut people up, it should be to help them get the best performance. Download this app from Microsoft Store for Windows 10. Download this app from Microsoft Store for Windows 10. Quick question, my new server (software raid) shows 284 mb/S and my old server shows 3000 mb/S (Hardware raid controller). CrystalDiskMark is software which can benchmark hard drive speed. Which one would be similar to the Data Warehouse, still the SEQ? Also, i was watching your TechED talk on this and you mentioned you’d prefer a size of 8GB for testing, but it didn’t exist at the time. Steve. Production Seq read 2150 MB/s Production Seq write 502 MB/s Azure Seq read 67 MB/s Azure Seq write 67 MB/s. CrystalDiskMark is a freeware utility for measuring disk performance. A baseline has to established by collecting and analyzing the theoretical capabilities taking into account the configuration. There are many SAN’s out there for whatever reason they have max cap on IO’s on each LUN, in your case it might help to have data and log files put on separate drives. I ran it a few more times with 5 passes at 4000MB and hit a range if 350 to 400MB/s. Your email address will not be published. BTW, there’s a text box at the bottom of the form that you can use to describe the test environment/date, etc — that way you can capture that info in your screenshots, rather than relying on file names. That’s exactly how open source projects get started – when someone needs something that doesn’t exist. Dustin – yep, ideally there’d be some kind of Geekbench-style repository for storage data. CrystalDiskMark; Main Window; Main Window. Does that happen to match up to the cable type that you’re using? The main purpose of benchmarking is to make sure that your SSD or HDD or is doing effectively. Comparing it to testing on the G: drive which most likely is local attached storage: Sequential Read (Q= 32,T= 1) : 760.456 MB/s Sequential Write (Q= 32,T= 1) : 796.739 MB/s Random Read 4KiB (Q= 32,T= 1) : 135.912 MB/s [ 33181.6 IOPS] Random Write 4KiB (Q= 32,T= 1) : 154.893 MB/s [ 37815.7 IOPS] Sequential Read (T= 1) : 563.322 MB/s Sequential Write (T= 1) : 336.619 MB/s Random Read 4KiB (Q= 1,T= 1) : 8.100 MB/s [ 1977.5 IOPS] Random Write 4KiB (Q= 1,T= 1) : 13.505 MB/s [ 3297.1 IOPS], Test : 4096 MiB [G: 14.9% (44.8/299.9 GiB)] (x5) [Interval=5 sec] Date : 2016/02/16 12:03:23 OS : Windows Server 2008 R2 Server Standard (full installation) SP1 [6.1 Build 7601] (x64).
