    Replacing Hard Drives

    Hi, I was just curious on how companies with thousands and thousands of hard drives replace all there hard drives because hard drives have a certain period of life. How would one replace them all when they are coming close to failing fully?

    Thanks!

    Well, they do not just replace it unless it failed :-)

    Hey, what if there were 1000 drives bough and installed on the same day and each of these drives has the same life time?

    As net already stated it wouldn't be changed until the hardware was about to fail (error messages) or until it actually failed.

    Good hard drives will have at least 3 years lifetime, maybe even more. Some hard drives have 5 years warranty. And after 2-3 years of operation your hardware will already be old and outdated so you should be replacing the whole server with a new one anyway. The old server will use too much electricity and there will be newer servers that use less electricity yet provide more computing power.

    Make sure to use Raid with hot swap bays. Also, any drive with SMART usually does a good predictive failure...so basically, a drive fails or starts to fail, grab a replacement, and simply remove the old drive, slap in the new.
    This is how I do it day in / day out.
    If you don't have hot swap, you have to bring the server down to do such, and if you are, on top of that, not using Raid...then it's going to be a pain, and one would deserve any woes harkened unto them!
    This is the best signature in the world....Tribute!

    Sometimes the life cycle of the entire line comes faster than the actual failure of drives. Meaning I may have deployed 100 Dell PE2950s an year or two ago and I'm phasing them out with newer R710s today.

    I'm with mugo. I replace failed drives day in & day out. It's not an issue w/ real RAID + hot swap. Even w/ SW RAID, is not that bad. It's a real pain when the vendor wants you to run this and that diagnostics before honor the support, when you can't afford prolonged downtime.

    Having severs with customer data on it without proper monitoring is like having one night stand without using protections - eventually, there will be an 'oh s**t!' moment.
