SANIQ 10 (Lefthand OS) soon to be released

LeftHand OS v10.0: More integration, performance and management capabilities

On the 4th of December the next version of SAN/IQ (now named Lefthand OS) will be released with some  nice new features:

  • Increased Windows integration – We now offer Active Directory integration which will allow administrators to manage user authentication to HP StoreVirtual Storage via the Windows AD framework. This simplifies management by bringing SAN management under the AD umbrella. With 10.0 we are also providing support for Windows Server 2012 OS.
  • Improved performance – The engineering team has been working hard with this release and one of the great benefits comes with the performance improvements. LeftHand OS version 10.0 has numerous code enhancements that will improve the performance of HP StoreVirtual systems in terms of application performance as well as storage related functions such as snapshots and replication.  The two major areas of code improvements are in multi-threading capabilities and in internal data transmission algorithms.
  • Increased Remote Copy performance – You’ll now experience triple the performance through optimization of the Remote Copy feature that can reduce you backup times by up to 66%.
  • Dual CPU support for VSA – In this release, the VSA software will now ship with 2 vCPUs enabled. This capability, in addition multi-threading advancements in 10.0, enhances performance up to 2x for some workloads. As a result of this enhancement, we will now also support running 2 vCPUs in older versions of VSA. So if you’ve been dying to try it, go ahead. Our lab tests with SAN/iQ 9.5 and 2 vCPUs showed an up to 50% increase in performance.
  • Other performance improvements – 10.0 has been re-engineered to take advantage of today’s more powerful platforms, specifically to take better advantage of multi-core processors, and also improves the performance of volume resynchronization and restriping and merging/deleting snapshot layers.

    Hi Marcel,

    I have been reading your posts on the HP forum regarding the VSA LeftHand solution, and the bottleneck we are experiencing with our current setup.

    I have 3 hp proliant DL380 G7 with dual cpu and 48GB of RAM.
    2 of them have a sas expander card with a 1GB flash + battery pack on the raid controller. We have added a extra drive cage, and have 16 disks of 300GB in one RAID5.

    We have installed VMWARE 5 and installed on both the VSA Software. But performance is very slow. Installing a 2008 R2 server takes about 55 minutes to complete; which is a complete disaster.

    Both the VSA’s are in one vSwitch where both the iSCSI and the VSA Network are connected, with two NIC’s. They are physical connected to a 2510 procurve.

    We do have the VMXNET3 adapter for the appliance, is this my bottleneck? Or should I postpone this to the 10 release?

    PS: I have already given 2 vCpu to the VSA software and 5GB of RAM. All versions are installed from the 9.5 version, and all patched.

      Hi Thomas

      First of all the procurve 2510 isn’t a suitable iscsi switch cause it has insufficient port packet buffers.My advice is to use 2910al or 3500al switches.

      How many nics do your vsa’s have?
      1 or 2? did you removed the first flexible nic from the vm config?

        Hi Marcel,

        “did you removed the first flexible nic from the vm config?”

        Should I remove the first nic and use only the second VMXNET3 adapter?

        We have very poor performance with our two VSAs. If I shutdown on VSA (either one), then performance is ok.
        Netraid 10 IO seems to slow down dramatically.

        Thanks,
        Peter

    Hi Marcel,

    Sorry to response so late. I have made a mistake, the 2510 are for the LAN, the 2910 are the iSCSI switches.

    For the moment I have found the reason why the VSA is so slow. Apparently the battery cache of one of the servers was DOA without reporting this in the ADUC. So that is why we had so dreadfull performance. At the moment this is resolved.

    Thanks for assisting.

    Greetings,
    Thomas
