  • 1.  SSIM Upgradation

    Posted Apr 13, 2012 12:11 AM

    Hi All,

    One doubt regarding SSIM Upgradation.

    What is the Max. Memory upgradation capacity of SSIM Appliances. SSIM 9650 & 9630.

     

    Recently i have upgraded 2 of my 9650 appliance capacity to 32 GB.

    I just wanted to confirm whether i need to do any addition configuration to fully utilize this memory or no additional configuration is required for this.

     

    SSIM version is 4.7.3

    Hi, SSIM 4.7.3 is based on Red Hat Enterprise Linux 4.8 ES, and every RHEL 4.x ES release has certain limits related with max. memory and CPU sockets. If I remember correctly, RHEL 4.8 ES can handle with max. 16GB RAM and max. 2 CPU sockets. Of course SSIM should work with 32GB but I doubt if OS or application utilize more than 16GB. Regards

    Hello,

    The correlation appliance used in my environment have 24GB RAM because we had several pre-configured servers from our hardware provider. So we used those machines and SSIM works fine so far...

    I'm also confused regarding this question.

    In the kernel list in this article <TECH164514> it is stated that the kernel of SSIM 4.7 MP4 is hugemem.

    When i list my SSIM appliance (4.7 MP4) for installed kernels the result is: kernel-smp-2.6.9-100.EL (SMP kernel).

    Also i found the following info:

     

    RHEL-4 32-bit kernels: 
    • i686 - no PAE, no hugemem patches, can address up to 4GB memory
    • i686-smp - PAE, no hugemem patches, can reliably run with around 16GB
    • i686-hugemem - PAE, hugemem patches, can reliably run with 64GB

     

    Can someone clarify this for me?

    Disd you install SSIM on VMware ESX?

    On ESX hugemem kernel can't be used.

    On physical machine we use hugemem kernel.

    I have a doubt!!

    I have SSIM 4.7.3.50 installed.

    I have recently upgraded my correlation box to 32 GB from 16 GB.

    when i do cat /proc/meminfo

    I can see 32 GB memory installed.

    But when i run ls -l /opt/Symantec/simserver/svclauncher.cfg

    i get following output:


    lrwxrwxrwx  1 root root 44 Mar 25  2011 /opt/Symantec/simserver/svclauncher.cfg -> /opt/Symantec/simserver/svclauncher.cfg.16GB


    Does that mean out of 32 GB SSIM is using only 16 GB??

    I agree with Avkash K, there are only three available svclauncher templates - for 4, 8 and 16 GB of RAM. Back to RHEL limits: https://www.redhat.com/products/enterprise-linux/server/compare.html According to Red Hat sources RHEL 4.x ES supports only 16GB. Hugemem kernel adds support for more RAM but svclauncher should be modified very carefully because memory settings assigned to each servlet must fit into 32-bit Java limits such as max 2GB memory per process. It's very hard to say how SSIM will behave with custom svclauncher settings...
