    Server hardware recommendations for new 3–4 node Proxmox VE / Ceph cluster

    At work, been migrating 13th & 14th-gen Dell VMware clusters over to Proxmox Ceph. Swap out the PERC RAID controllers for Dell HBA330s IT-mode controllers, since Ceph/ZFS don't work with RAID controllers. If I was buying new, I will go with single-socket high-core CPUs (64/96/128/etc), like AMD...

    CEPH & ZFS Using a PERC H755n

    As you know, ZFS & Ceph really don't play nice with RAID controllers like Dell PERCs. While it's true you change the PERC from RAID mode to IT-mode, I've had issues in the past with the megaraid_sas driver. That's why I switch out Dell PERCs for Dell HBAs, like the Dell HBA355i. It uses the...

    ZFS with PERC H745: is RAID0 the same as JBOD?

    On 13th- & 14th-gen Dells PERCs, have to delete the virtual disks before switching it to HBA-mode. Call it a quirk. I've also had issues with the megaraid_sas driver in the past, so I just swap out the PERCs for Dell HBA330s, which is a true IT-mode strorage controller. It uses the much simpler...

    Who runs Proxmox on the oldest hardware ?

    Have it running on a Dell R200 which was released back in 2007. Was running LXCs but now it's a PBS instance. Mirrored ZFS drives. Makes for good small LXC/PBS server but that's all it's good for.

    [SOLVED] Trying to enable nested virtualization results in perfomance loss on vm

    I don't run nested virtualization using Windows guests but do with Linux guests especially with Proxmox, ie, phystical Proxmox -> vitual Proxmox -> Linux guest. I do use CPU type of 'host' as your screenshot shows. As for number of cores, I see you use '16' which is quite alot, IMO. I use the...

    [SOLVED] Dell R730 cannot boot Proxmox 9 kernel (boot loop after install)

    For 13th-gen Dells, enabling X2APIC & IOAT DMA resolves the issue. I don't use SRV-IO.

    VMware Migration - Scenario & Seeking Advice

    I run Proxmox on 10th through 14th-generation Dells at work. Yup, this is with latest Proxmox 9.1.x with latest 7.0.x kernel. No issues. I just made sure the machines has the latest firmware and BIOS/UEFI. I do NOT use any RAID controllers (PERC). I swapped them out for IT-mode controllers...

    [SOLVED] Support for PERC H310 Mini on PVE9

    You are better off flashing the 12th-gen PERCs to IT-mode via https://fohdeesha.com/docs/perc.html Do NOT skip any steps and record the SAS address. No issues in production.

    9.1.1 Installation issue with PERC H730 Mini

    Dell HBA330 mini-mono versions are definately for 13th- and 14th-gen Dells. For 12th-gen Dell PERCs (H310/H710/H710P/H810), use https://fohdeesha.com/docs/perc.html. No issues in production. Do NOT skip any steps and take your time. If you want to boot from the drives, flash both a BIOS & UEFI...

    Ceph 20.2 Tentacle Release Available as test preview and Ceph 18.2 Reef soon to be fully EOL

    Been testing EC pools with plugin=ISA technique=reed_sol_van with VMs with additional storage optimizations. Weirdly enought, it's faster in read operations than replication. Not complaining.

    Enterprise grade SSD recommendation for Proxmox host

    This. Look for PLP. I will also look for high endurance. I use Intel DC-S3710s for their 10 DWPD endurance.

    Cluster setup and HA configuration suggestions

    I've been migrating from VMware vSphere to Proxmox Ceph at work on 13th-gen Dells. Ceph really, really, really wants homogeneous hardware, ie, same CPU, RAM, NIC, storage, storage controller, firmware, etc, etc. I swapped out PERCs for Dell HBA330s since I won't want to deal with PERC HBA-mode...

    How to Configure iSCSI shared storage for thin Snapshots properly

    Seeing that the MD3200i is a legacy SAN, maybe cheaper to migrate to Ceph. Been migrating VMware legacy SAN infrastructure to Proxmox Ceph. IMO, need a minimum of 5-nodes. So, can lose 2 nodes and still have quorum. Isolated switches for Corosync and Ceph. All hardware the same. No PERCs, using...

    9.1.1 Installation issue with PERC H730 Mini

    A better option, IMO, is to use a pure IT-mode storage controller like a Dell HBA330. Extremely cheap to get. Uses the much simpler mtp3sas driver and don't have to deal with PERC storage drama. No issues in production.

    Repurposing vxrails hardware with Ceph

    Been migrating 13th-gen Dells (R630s & R730s) from VMware to Proxmox Ceph. Clusters range from 3- to 9-nodes, all odd number for quorum. All hardware is the same (RAM, CPU, NIC, storage, storage controller, firmware). Swapped out PERCs for Dell HBA330s since I don't want to deal with PERC...
