Groovy. RAM can be added later, CPU cores are a lot harder to add after the fact ;) >> Agree, I would will have enough slots in my case to extend them 512+GB Perfect. >> > I am inclined to 7.68TB NVME which will allow me more expansion space in > future Excellent strategy. Getting additional servers approved, ordered, and delivered can sometimes take as long as a year, so having a way to expand more quickly is valuable. > with Chassis Configuration 2.5" Chassis with up to 24 NVMe Switched HWRAID > Drives, Dual Controller, Front PERC 12 Hard Drives (PCIe SSD/Flex Bay) This isn’t the droid I would look for, unless you expect a future need to provision SFF HDDs. I would suggest, assuming the R7625: Chassis with up to 24x2.5” Drives NVMe Backplane 2.5" Chassis with up to 24 NVMe Switched Direct Drives Unless you need HDDs in the future, you don’t need a PERC RAID or plain HBA. Selecting the above should remove that from your configuration. Alternately you could select Chassis with EDSFF drives Chassis with up to 32 E3.S NVMe Drives || Chassis with up to 32 E3.S NVMe Drives with 4xE3.S Rear NVMe Depending on whether you favor the U.2 or E3.S form factor. Either way you have three strategies for boot drives: A) Use two front-panel drives with MD mirroring B) Provision optional rear drives with MD mirroring C) Add BOSS and use mvcli or option ROM utility to set up HBA mirroring >>>> _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-le...@ceph.io
