HP DL360 G7 Hypervisor
[[Category:Proxmox]
This describes the build process for Proxmox 8.2 on existing Compaq/HP DL360 G7 Server
These have served me well for several years and while the could stand to be upgraded, they are maxed out on CPU, RAM and disk, and have plenty of life left in them. As I'd installed Proxmox years ago, and before I knew what I know now regarding the naming local storage for ZFS pools, I decided to rebuild them during the 8.2 upgrade.
Config
The Servers consist of the following:
2x Xenon X5675 @3.07 GHz (12 real/24 virtual cores) 192 GB (12x16gb DDR3 1600 MHz) RAM 8x SAS 1.6 TB SSD HUSMM141CLAR1600 LSI SAS2308 storage controller Mellanox MT27520 ConnectX-3 Pro dual 10g Nic
Disk Layout
I use local ZFS storage on most of my HVs, and as such proxmox cannot migrate or replicate VMs or CTs from nodes with different pool names. By default everything is rpool, and rpool is the root disks, which on other newer servers are used for booting only. This means that one of the core features of proxmox will not function unless it's fixed.
As I'm not wanting to invest more in these servers and figure out how to put a boot disk in, we must boot off the existing SSD's. This has the limitation of requiring 512b sector disks and GRUB as the servers are too old to use UEFI boot and native 4k disks. Proxmox does write to it's root disk so vmware kinda boot (ie USB boot or DOM SATA) will not work, but the IO requirements are not that intense. The decision was made to use part of the disks as a raidz3 pool with 16gb per disk making 80gb reserved for the root device.
The localDataStore pool will be raidz1 with the remaining space on each device. zraid1 was chosen as each VM is fully backed up and even if >1 disks fail, the server will still boot as we can lose 3 disks before it's unbootable. I've not lost a disk on these servers before either, and cold spares are on site.
We'll also pad out the space between the root pool partition and the localDataStore partitions with a 16GiByte partition, allowing easy expansion of the root pool if needed in the future. Finally we'll leave 16MiB of space at the end of each disk.
Thus we'll have the following:
Disk /dev/sda: 3125627568 sectors, 1.5 TiB Model: HUSMM141CLAR1600 Sector size (logical/physical): 512/4096 bytes Disk identifier (GUID): 7E89E66A-F81F-431A-B71A-F8BA7583CDC1 Partition table holds up to 128 entries Main partition table begins at sector 2 and ends at sector 33 First usable sector is 34, last usable sector is 3125627534 Partitions will be aligned on 8-sector boundaries Total free space is 32774 sectors (16.0 MiB) Number Start (sector) End (sector) Size Code Name 1 34 2047 1007.0 KiB EF02 2 2048 2099199 1024.0 MiB EF00 3 2099200 33554432 15.0 GiB BF01 4 33554440 67108871 16.0 GiB BF01 Solaris /usr & Mac ZFS 5 67108872 3125594767 1.4 TiB BF01 Solaris /usr & Mac ZFS
