Is there an ability to adjust the IOPS level/range that a storage disk can provide? RRS feed

  • Question

  • O/S - CentOS 6.5
    VM type: Extra-small, 768MB RAM

    I have an extra 20GB storage disk that was provisioned for a VM to function as a DBDATA disk. Spot testing I can tell this additional storage disk performs much better than the boot disk/drive (~2000 IOPS versus 120 IOPS) where my O/S is installed.

    I searched around the portal and dashboard site, but I could not find a dial or slider switch where I could set set/tweak the IOPS settings for the attached storage drive.

    Questions

    1) Does anyone know if a configurable IOPS setting is available in the portal/dashboard area somewhere?

    2) As mentioned, this "additional" storage drive can perform much better than the boot disk (~2000 IOPS compared to ~120 IOPS), is there a reference for what the maximum IOPS are that these storage drives can deliver?

    You could set IOPS on your VM. About this issue, I recommend you watch this video form channel 9 (http://channel9.msdn.com/Events/TechEd/NorthAmerica/2013/MDC-B345#fbid=). You could see the [ 44:40 ] Storage Quality of Service ( QoS ) .

    • Enables consistent SLA delivery
    • Dynamically configurable while VM is running
    • Set Maximum IOPS Threshold for Overactive / Disruptive VMs
    • Set Minimum IOPS Alert Threshold
    • Learn more in Windows Server 2012 Hyper-V Storage Performance ( MDC-B345 )

    Hope this helps.
