      We have one of our boxes (R2208GZ4GC) that's being used as a platform for a client recovery.

      It's set up with:
      2x 240GB Intel SSD DC S4500 RAID 1 for host OS
      2x 1.9TB Intel SSD D3-S4610 RAID 1 for VMs

      It's working great for the seven or eight VMs currently stood up on it. RAID is provided by Intel RMS25CB080 (IIRC) series module.

      What you have is wasted SSD performance and cost and storage capacity.

      The performance pays for itself when they are in full swing with very little to no noticeable latency. And, updates run a lot faster.

      Cost wise, it's not that much of a step.

      What? The performance of the hypervisor is meaningless - assuming that's what's on the SSDs and not the VMs. So yeah, the SSDs would be a waste.

      As for updates - how often are you updating the hypervisor that you care that much about how fast updates run on the hypervisor?

        A spindled RAID 1 for the host OS would be a real pain for updating the host. The CUs get yuge and time consuming.

        EDIT: A pair of Intel SSD DC series SATA drives are not expensive at 240GB or smaller. In the overall scheme of things the biggest cost on the host are the CPUs and memory then the storage subsystem depending on setup.

          @PhlipElder it's still added cost for little to no gain.

          Try and justify this poor decision all you want. But it was and is still a poor decision.

              OK fine - the CUs for the hypervisor get big - and? you're likely only patching them monthly, if even. How much time are you saving by using SSD there compared to HDD? 1 min? maybe 5? That's a lot of time to justify the cost of SSDs, even if they are only $99/ea. Why have them at all? Why not just install the hypervisor on the RAID 10 your VMs are on, save yourself $200.

              Yeah I get it - it's a $3,000+ server, $200 is nothing... but it's still about 8%+... so it's not nothing...

                Y'all realize WD/HGST no longer makes 2.5" SAS spindles? Seagate won't be too much further down the road. They've reached the end of the road.

                As far as the dollar figure goes, where there's value there's value. That too is all in the eye of the beholder. Our clients see it as we're delivering flash in our standalone and clustered systems.

                We shall need to agree to disagree.

                  Wait - If having the hypervisor be fast for updating - wouldn't it be even more important to have the workloads themselves be faster too? How are you not justifying putting all the data on SSD?

                    See my earlier recommendation. Our starting go to for all servers has been 8x 10K SAS in RAID 6 with two logical disks with the aforementioned performance specifications.

                    SSD in standalone hosts has been an option cost wise for a few years now depending on data volume.

                    Ultimately, it's up to the customer/client. Here's $$$ for spindle solution and here's $$$$ for SSD solution and here's the benefits of one over the other. They make the choice.

                      Ultimately, it's up to the customer/client. Here's $$$ for spindle solution and here's $$$$ for SSD solution and here's the benefits of one over the other. They make the choice.

                      But it sounds as if you're stating that a faster booting Hypervisor is some miracle baby jesus tech. When it's just sunk cost.

                        We have one of our boxes (R2208GZ4GC) that's being used as a platform for a client recovery.

                        It's set up with:
                        2x 240GB Intel SSD DC S4500 RAID 1 for host OS
                        2x 1.9TB Intel SSD D3-S4610 RAID 1 for VMs

                        It's working great for the seven or eight VMs currently stood up on it. RAID is provided by Intel RMS25CB080 (IIRC) series module.

                        What you have is wasted SSD performance and cost and storage capacity.

                        The performance pays for itself when they are in full swing with very little to no noticeable latency. And, updates run a lot faster.

                        Cost wise, it's not that much of a step.

                        What? The performance of the hypervisor is meaningless - assuming that's what's on the SSDs and not the VMs. So yeah, the SSDs would be a waste.

                        As for updates - how often are you updating the hypervisor that you care that much about how fast updates run on the hypervisor?

                        I was thinking more for the guests than the host.

                        A spindled RAID 1 for the host OS would be a real pain for updating the host. The CUs get yuge and time consuming.

                        EDIT: A pair of Intel SSD DC series SATA drives are not expensive at 240GB or smaller. In the overall scheme of things the biggest cost on the host are the CPUs and memory then the storage subsystem depending on setup.

                        OK fine - the CUs for the hypervisor get big - and? you're likely only patching them monthly, if even. How much time are you saving by using SSD there compared to HDD? 1 min? maybe 5? That's a lot of time to justify the cost of SSDs, even if they are only $99/ea. Why have them at all? Why not just install the hypervisor on the RAID 10 your VMs are on, save yourself $200.

                        Yeah I get it - it's a $3,000+ server, $200 is nothing... but it's still about 8%+... so it's not nothing...

                        Y'all realize WD/HGST no longer makes 2.5" SAS spindles? Seagate won't be too much further down the road. They've reached the end of the road.

                        As far as the dollar figure goes, where there's value there's value. That too is all in the eye of the beholder. Our clients see it as we're delivering flash in our standalone and clustered systems.

                        We shall need to agree to disagree.

                        TTFN

                        Wait - If having the hypervisor be fast for updating - wouldn't it be even more important to have the workloads themselves be faster too? How are you not justifying putting all the data on SSD?

                          I agree with Dustin - you make it seem like putting the hypervisor on SSD is something that matters - that it's a choice that could be good - and that's so rarely true. Personally it's so rarely true that I wouldn't even consider it personally.

                          Now - an all SSD or all HDD - that's totally a different conversation - definitely choose what is right for the customer (or what they choose is right for themselves)... but that is HUGELY different than the hypervisor being on SSD and the VMs being on HDD - that just seems like a complete waste of money.

                            Point of clarification: We deploy all 10K SAS RAID 6 or we deploy all-flash.

                            Please point out where it was said that we deploy SSD for host OS and HDD/Rust for VMs?

                                  4X 2TB 12Gb/s (for Data)
                                  I was planning on using Raid1 for the OS and then Raid5/6 for the Data storage

                                  Right there. Post #1

                                  That's Joel not @PhlipElder

                                      We have one of our boxes (R2208GZ4GC) that's being used as a platform for a client recovery.

                                      It's set up with:
                                      2x 240GB Intel SSD DC S4500 RAID 1 for host OS
                                      2x 1.9TB Intel SSD D3-S4610 RAID 1 for VMs

                                      Here it is.

                                        Dustin found the correct quote.

                                        oh how both @PhlipElder and @joel had very similar posts. 😛

                                          @PhlipElder if this isn't what you mean - We're happy to correct our understanding.

                                            Yeah, special case. Note in the quote "We have one of our boxes (R2208GZ4GC)..."

                                            1.9TB SSDs are ours and just enough space to work with for their setup thus the 240GB for host OS. We have another pair of 800GB Intel SSDs set aside as we may actually need more space than anticipated.

                                            Since this is a recovery situation we can't afford any extra time waiting on spindles. The server gets delivered this weekend and the cluster there rebuilt. It's a 2-node asymmetric setup (Intel R1208JP4OC with DataON DNS-1640 JBOD and 24x HGST 10K SAS spindles).

                                            We get our box back after the project is complete.
