  • 1.  Recommendations for a new server

    Posted Oct 13, 2023 08:11 AM

    Currently for an ESXi 6.7 a Xeon E5-2450 CPU, 20GB and 4x500GB HDDs in RAID5 are used.

    There are only 4 office users and only the following is installed on the Host:

    • a Windows Server 2016, for a single SQLExpress DB;
    • a Linux server used only for folders shared between the 4 users;
    • a Linux server for web applications.

    We would like to replace the server with a new one.
    I was thinking at least 32GB, at least 16 cores.

    For the disks I thought I would focus more on safety than on performance.
    On the NAS, using ZFS I have RAIDZ-2 with two parity disks and system snapshoots.
    On the host server I will probably still have to let the controller handle everything, so what do you suggest?
    6 HDD in RAID-6 or some other solution?

    Today we have a Dell PowerEdge. Do we always change to Dell or do we go to HPE?
    What do you think of Lenovo servers?

     

    Thanks in advance for any advice.

    Why do you need 16 cores and RAUD-6? Isn't that overkill for only 3 servers?

    My opinion you can use an "HPE ProLiant DL20 Gen10" can go up to 8 cores, 64GB RAM and RAID5

    Used it in the past, good solid server. Never had problems with it.

    8 cores are the same as now.
    If in next future I want to install other VMs I will already find myself with the bottle full to the cap.

    I wouldn't want RAID5 just to be on the safe side.
    In many years I have never lost a disk, but I bet that two disks fail at once.

    Some thoughts, without knowing your workloads, and future plans:

    • if you are happy with Dell stay with it, although the other two vendors are good as well. Depending on your budget, a R760xs model may be what s.th. that to look at (redundant power, several network ports + iDRAC Enterprise, ...)
    • RAID5 (with host-spare) or RAID6 (without hot-spare) may not make a a big difference, if you get a good RAID controller with 2-8GB cache.
    • 16 cores seems to be a good decision. This will give you room for future needs, and you do not need to purchase additional core-licenses for Windows
    • don't save on RAM. In most environments that I saw, this is often an issue.
