Hardware recommendation

[muellermi]

Hi,
Currently we are running an elder VMware configuration within our network which uses an elder SAN (100TB).

We're thinking about using Proxmox instead. And I read about a recommodation to use CEPH or ZFS in favor of a SAN. Currently we're running apx. 25 virtual servers, one of them acting as fileserver for our common natwork share. Most of the servers host small services with a memory consumption of 4-32 GB. There is only one big virtual machine which needs 128 GB RAM and 3 with 64 GB.

We're thinking of 3 HP Proliant for this setup. 512 GB RAM? Or more? Dual (RAID) SSD fdor OS? Non-Raid SSD for network storage? How many? Main focus on cores or on frequence rate?

Any recommendationis appreciated.

Thanks.
Michael

What about eg. 3x "Supermicro SYS-222H-TN, 2x 6710E, 768GB, 2x 960GB" and 1x DDN SFA400x2 with HDR200 (block checksum with autocorrect by read/scrub) dual connected to all 3 servers ?
In general I would this time prefere intel cpu's as there are so many kernel and vm problems with amd cpu's to actual pve 6.8 kernel active yet (depends on kernel hypervisor feature support development).
RAM and higher (but less cores) frequencies, I/O and IB/OPA network are key.
Good luck

Thanks Waltar.
Is Supermicro as good as HP Proliant? And how may we substitute a 100 TB SAN with 2x960 GB? I assume, we need a couple of more drives.
How does CEPH or ZFS maintain it's capacity? E.g. 60 TB on each node to achieve 100 TB?

Supermicro server are real only just functioning with missing stickers to all ports on back but therefore very cost effectiv.
The example keep just disk for os, all storage space is external managed EC-raid (erasure coding), 24x nvme included and nearly endless (up tp 900 additional hdds/sfa). The storage look inside servers as were internal. You can use as local or distributed file(system) or block storage any config, switch between or even couple of different storage layout/protocol technologies same time. (Ai(/E)400x2 are incl. internal lustre services, sfa without).

Thanks for clarification.

uhh... no.

It all depends on your dependence on HP's toolset (eg, ilo/ipmp, imc, infosite, etc.)

IF you use any of those, stick with HP. if you dont, or dont know what those are- sure, Supermicro can serve just as well.

SM BMC is working, yes it's compact. If you need a premium hw reseller I would even prefere Dell before HPE as you could even see bios values and could change them for next reboot time even while the os is still running, has nicer cooling regulation, better spare part support and even less expensive than HPE.
