    Default Upgrading the storage on a Dell R710

    I have a home lab with a Dell R710 running ESXI (free), its not quite run out of storage but it's got to the stage where I need to think what I do next.

    Its got a PERC6/i raid controller and 6 x 2TB drives in a raid I can't remember (I think RAID 6 as I have usable capacity about 7.28TB)

    Question 1;

    AIUI PERC6 is generally limited to 2TB Drives, so I will need to replace this with a H700 RAID controller, if I do this will it break the existing RAID or would it just continue working and all data remain.

    If it doesn't break it

    Question 2;

    I assume I'd just replace each drive one by one and wait for the raid to rebuild on the new drive before moving onto the next.

    Question 3;

    Once this is done I assume I would need to expand the volume in the Raid controller and then within ESXI before it's available to my VMs?
    “Live a good life. If there are gods and they are just, then they will not care how devout you have been, but will welcome you based on the virtues you have lived by. If there are gods, but unjust, then you should not want to worship them. If there are no gods, then you will be gone, but will have lived a noble life that will live on in the memories of your loved ones.”

    Pass - personally I would be looking at starting again - there is a reason why most NAS use JBOD's to avoid this type of issue.

    The RAID controller replacement it's easy-peasy - You can migrate the current virtual disk, just replace the RAID controller and from it's configuration select "import foreign configuration".

    For the upgrade with larger disks, it's not that straight forward, some controllers won't allow you to extend the VD or create a 2nd VD on the same disk. Check if the H700 will allow.

    In your place I would just go for a NAS that supports iSCSI or straight out NFS for the ESXi Datastores. Even 1Gbps network is fine for homelab.
