Expert Tips for Configuring SQL Server for SSDs and Virtual Machines

By Staff Contributor on March 26, 2015


A recent Information Week’s 2014 State of Enterprise Storage Survey indicates that 40% of respondents were using SSDs in disk arrays and about 39% deployed SSDs in servers, which is about 8-10 points up from the previous year. These figures clearly highlight that SSD adoption is increasing.

We brought together a group of expert DBAs, geeks and IT/System administrators to share some tips on configuring SSDs and storage for enhanced SQL Server performance. They joined hosts SQL Server MVP and SolarWinds Head Geek Thomas LaRock (@SQLRockstar) and Joseph D’Antoni, (@jdanton), SQL Server MVP and Senior Architect at Denny Cherry & Associates. We posed some key questions to the participants on the topic and here are some key takeaways from the conversation (you can read the full chat transcript at the end of this article).

Tip: Cost is the number one factor driving increased SSD adoption rates

Datachat participants were unanimous in stating that reduced cost was the primary reason driving increased adoption rates for SSDs. Increased demand for virtualization has invariably led to increase in demand for SSDs.  The other reasons for adopting SSDs are: lower mean failure rate than spinning media and lack of developers to tune virtualized environments.

Tip: It’s a myth that SSDs solve all performance problems

Because of the decreasing costs for SSD storage, it’s not uncommon to attempt to solve performance issues by adding SSD storage. But, as @SQLRockStar lamented, “Disk is rarely the problem: Its often bad code/design, or bad disk configuration.” New hardware such as SSDs drives only solve problems caused by disk. Joseph D Antoni also noted:

But, most agreed that SSDs do not offer a solution for many common problems such as:

  • SAN problems
  • Bad application
  • Hypervisor paging
  • Bad code and design
  • PEBKAC issue

Tip: CPU over allocation is a key performance metric for troubleshooting VMware

If you’re trying to troubleshoot performance of SQL Server on VMware, the key metric is the number of CPUs. Over-allocation of CPUs is bad. For SQL Server, it’s fair to look at all the same metrics that you would on physical servers. If you do not get your answers from this analysis, then it’s time to analyze the host. Some other metrics that help with troubleshooting include:

  • VM CPU ready time
  • SQL Server wait events
  • Activities in vCenter/SCVMM

Tip:  Common challenges with SSDs: include index rebuilds and sequential writes

Common complaints with  SSDs are that they aren’t good at index rebuilds and sequential writes. These are some unique challenges that are faced by tiered SANs. An improper DR (disaster recovery) plan can only add to your woes.

SQLRockstar RT @solarwinds: Q1: SSDs are not new tech, but becoming more popular. What factors are driving adoption rates? #datachat
jdanton @solarwinds A1: Cost have gotten a lot cheaper. I was looking at an old deck that had some pricing. And it’s huge. #datachat
SQLRockstar .@solarwinds A1: Costs, mostly. But there is also the belief that that hardware is more durable than it was previously. #datachat
jdanton @solarwinds A1: Also, virtualization tends to increase demands on a storage subsystem, and SSDs can help with that. #datachat
jdanton @SQLRockstar @solarwinds It’s interesting–based on data I’ve seen, SSDs have a lower mean failure rate than spinning media 1/2 #datachat
jdanton @SQLRockstar @solarwinds but perception is still there that it’s an issue. #datachat
DBABullDog @solarwinds @SQLRockstar A1 IMOO cost would be number 1 factor. Lack of developers to tune environments could be another factor #datachat
SQLRockstar .@solarwinds A1: Also, at this point, there is a lot of material on best practices for SSD usage and deployment. #datachat

solarwinds @DBABullDog Welcome back Daniel! #datachat
solarwinds Q2: What’s the number one mythunderstanding about SSDs? #datachat
jdanton @SQLRockstar The vendors have done a really good job writing firmware to do write balancing. #datachat
SQLRockstar RT @solarwinds: Q2: What’s the number one mythunderstanding about SSDs? #datachat
jdanton @solarwinds A2: 1) They fail frequently 2) They have to cost a ton of money 3) They cure all ills. #datachat
SQLRockstar .@solarwinds A2: That SSDs will solve all your performance problems. #datachat
DBABullDog @solarwinds glad to be here #datachat
jdanton @SQLRockstar @solarwinds But the SAN vendor sold me these magic beans with my SSDs. #datachat
DBABullDog RT @SQLRockstar: .@solarwinds A2: That SSDs will solve all your performance problems. #datachat
SQLRockstar .@solarwinds I rarely see disk as the bottleneck, it’s often bad code/design, or bad disk configurations. #datachat
solarwinds RT @SQLRockstar: .@solarwinds I rarely see disk as the bottleneck, it’s often bad code/design, or bad disk configurations. #datachat
SQLRockstar .@solarwinds A2: In many ways. SSDs represent “throw hardware at the problem” which only works if you know disk is the issue. #datachat
jdanton .@SQLRockstar @solarwinds I see a lot of storage bottlenecks. SSDs help with that  lot. #datachat
SQLRockstar RT @jdanton: @SQLRockstar @solarwinds But the SAN vendor sold me these magic beans with my SSDs. #datachat
SQLRockstar .@jdanton @solarwinds My SAN vendor bought me sushi once. No magic beans though. Now I feel I got screwed. #datachat
jdanton .@SQLRockstar @solarwinds It’s hard to tune a system where tempdb has 600ms write latency. #datachat
DBABullDog @solarwinds @SQLRockstar A2 that Best application and database practices can be ignored and thrown out the window #datachat
SQLRockstar .@jdanton @solarwinds Yep, when storage is the issue, SSDs can help. Agreed. #datachat
solarwinds RT @josh_odgers: @jdanton @SQLRockstar SSDs in the wrong location can make no difference. Keep perf teir close to the app. #datachat
SQLRockstar .@jdanton @solarwinds Chances are the disk itself isn’t the reason for 600ms latency. #datachat
jdanton .@josh_odgers @SQLRockstar @solarwinds Good point–they are best treated as a limited valuable resource in any infra arch. #datachat
datachick RT @solarwinds: Q2: What’s the number one mythunderstanding about SSDs? #datachat That their failure behaviours are same as spinny ones.

josh_odgers @solarwinds Adding SSD shelves behind a saturated central storage controller or storage area network wont help. #datachat
SQLRockstar .@AirborneGeek @solarwinds I suppose it depends on the system, and if we are talking OLTP vs OLAP expectations. #datachat
jdanton .@josh_odgers @solarwinds Great point–SAN configuration doesn’t get a lot of press, but it’s key for good perf. #datachat
SQLRockstar .@AirborneGeek @solarwinds But IME a few code changes can make a huge improvement, quickly. #datachat
josh_odgers @solarwinds If the NIC/HBA/Queue depths is the point of contention, an All flash array is not going to solve your problem. #datachat

SQLRockstar RT @solarwinds: Q3: What are the key performance metrics you look at when troubleshooting VMs and why? #datachat
jdanton .@solarwinds A3: In terms of SQL Server, I initially look at the same things I look at on physical. But I also look at  1/2 #datachat
SQLRockstar .@solarwinds A3: VM CPU Ready Time is my favorite, followed by SQL Server wait events. #datachat
solarwinds Q3: What are the key performance metrics you look at when troubleshooting VMs and why? #datachat .
jdanton .@solarwinds A3:  the number of CPUs (vCPU overallocation is bad). Also, want to look at other activites in vCenter/SCVMM. #datachat
SQLRockstar .@ToddKlindt @AirborneGeek @solarwinds You know you can just use O365 instead, right? #datachat
SQLRockstar RT @solarwinds: Q3: What are the key performance metrics you look at when troubleshooting VMs and why? #datachat .
SQLRockstar .@jdanton @solarwinds A3: Oh yes, over-allocation is also something I look at right away. #datachat
DBABullDog @solarwinds @SQLRockstar most cases I take the same approach as with physical. If answers are not provided start looking at host #datachat
jdanton .@DBABullDog  @SQLRockstar I had one case where PLE suddenly dropped dramatically. The memory wasn’t reserved and VMW took it. #datachat

jdanton .@SQLRockstar @DBABullDog Reserving at the hypervisor, is what I usually recommend.  #datachat LPIM can have some bad OS impacts.
SQLRockstar .@jdanton @DBABullDog @mrdenny I used to recommend LPIM on VMW until recently I was persuaded to change my mind slightly. #datachat
jdanton .@SQLRockstar @DBABullDog @mrdenny Also, never set min/max memory to the same value. #datachat
DBABullDog RT @SQLRockstar: .@jdanton @DBABullDog @mrdenny I used to recommend LPIM on VMW until recently I was persuaded to change my mind slightly. …
SQLRockstar .@jdanton @DBABullDog @mrdenny Ah, there are two cases where you *might* want min=max. One case is multi-instance. #datachat
SQLRockstar .@jdanton @DBABullDog @mrdenny I forget the other case…more scotch might jog my memory. #datachat
jdanton @SQLRockstar @DBABullDog @mrdenny There is this though. https://t.co/Gv3upb8Qyj #datachat
solarwinds Q4: Do SSDs and flash arrays solve everything? #datachat
jdanton .@SQLRockstar @DBABullDog @mrdenny Multi-instance is usually better addressed with startup triggers, or something. #datachat
jdanton .@solarwinds A4: If everything is taking a lot of money out of you account, yes. They are really good at a lot of things. 1/2 #datachat
SQLRockstar .@jdanton @DBABullDog @mrdenny Yeah, that’s one of the BOL entries I asked to be updated to not say min=max. #datachat
josh_odgers “@solarwinds: Q4: Do SSDs and flash arrays solve everything? #datachat” < Not without solid supporting infrastructure and app architecture
jdanton .@solarwinds A4:They stil have SAN problems like mentioned earlier (controller overload etc),but they offer excellent performance. #datachat
SQLRockstar .@jdanton @DBABullDog @mrdenny There’s also the fact that SQL Server “paging” is not the same as Windows O/S paging. #datachat
