Thanks in advance to all the storage experts out there.
I've been wanting to get a small Ceph cluster up for some time and finally have some budget to start spending
I want to start with a 5 node setup and use the experience gained to assist me with a deployment for the office at a later date. I'm planning to use dual socket v1/v2 intel scalable 24 bay servers (pcie-gen3) with Mellanox 100G Connect-X/4/5 NICs and 100G switches (SN2100)
I'm seeking some advice on the following:
Do I consider using newer gen NVMe SSD's like for example the Micron 7450 Max over the pervious flagship being the 9300 Max considering that my chassis can only use U2/PCIe3 4x?
I may not see any the performance benefit today but future proof my investment for newer hardware once I life cycle my current lab and can make use of PCIe4.
Alternately do I opt for the cheapest cost per TB of NVMe being something like the Intel 4510 series?
Am I limiting myself in terms of overall performance by opting to use a older gen NVMe or would this be negated by CPU/s and NIC speed should I opt to use more than 8 disks per node?
I guess this question kind of falls in-between a Ceph and a hardware section.
Are there any other NVMe SSD's that I should be considering?
Datasheet 7450/PRO/MAX Link
