  • Monitoring Hardware RAID and RAM

    hi
    One of my server is in very critical condition. I have been monitoring its hardware using Performance monitor. The results from Perf monitor shows that there are page read/write faults exist in my system. There are errors related to memory read/write and hard disk read /write. I have to check is it RAM or RAID is causing problem. Are there any utilities or applicaiton that could help me in checking RAID and RAM. I have to be 100% sure that either RAID / RAM or both are faulty
    thanks

    MemTest will check the RAM. Your server should have RAID monitoring software for you to check the array.
    1 1 was a racehorse.
    2 2 was 1 2.
    1 1 1 1 race 1 day,
    2 2 1 1 2

      Are you referring to the page faults/sec performance monitor counter? If so, a page fault is not a fault it is a page operation and is perfectly normal. Windows will page data out to memory or hard disk (pagefile) as a normal course of it's operation. This is not bad unless you have exsessive paging. The pages/sec counter monitors paging to memory and the page faults/sec counter monitors paging to memory and hard disk.

        As Biggles mention memtest is the best memory testing application i have ever used.

        Your RAID cards should also have testing software.

        Your hard drive manufacturer will also have a testing program to test the drives. Seagate's is called Sea Tools for example.

          Thanks for help guys
          joeqwerty, the pages fault / sec are going more than acceptable threshold
          I will use test RAM and see what are the results I will get. i will confirm the RAID manufacturer and see that they contain any monitoring tools on their web site. Is it any general utility that we can use to monitor RAID?
