      So to summarize this before we get to deep into the topic.

      You're in an IPOD, and are looking to bring the NAS storage on-board to your servers.

      • We need to know how much storage your SAN has.
      • What your daily delta is for your data change (data growth)
      • What if any your backup solution you have
      • What RAID Configuration you're considering
      • What your IOPS are (per server and SAN)
      • That you're on ESXi (VMWare)
      • Price is a big decision factor

        Our SAN has 7.2TB running RAID 10, so approximately 3.6TB usable. There is about 415GB free. I like VMware and we own it so I hate to move away from it. We are a non-profit so our cost is feasible both on the VMware and Microsoft side.

        We have these servers now:
        2 DCs
        1 Exchange Server - hoping to move to 365 in future
        1 File Server
        6 Application Servers - 2 for our EHR software, 1 Spiceworks, 1 for our old EHR software, and 2 for smaller applications
        2 Terminal Servers - Will be adding a 3rd once we have the capacity
        1 vCenter Server
        1 WSUS Server
        1 SEP Server

        We probably don't NEED HA. We do have two decent servers so could probably drop down to one and use the second as a backup in case the first one goes down. I don't know the answer on the IOPs.

        I would be interested in the cost to contract with NTG to run DPACK.

          7.2TB (and then some storage as well) should be easily achieved in the servers you have* (how many usable drive bays are each server?)

            NTG would be happy to help you. You can reach out via chat and we can connect.

              Currently there are 8 drive bays, but if I remove the optical drive I can expand to 16.

                Well that's fine an optical drive is seldom used now anyways.

                Which if you really needed you could probably live with a USB 1.

                Are those a SFF (2.5" in bay)

                    Depending on your IOPs, you could be looking at SSD or HDD storage.

                    You think you can get away with one server for your entire workload? That definitely makes things easier.

                    You didn't mention what you are doing for backups?

                    You didn't mention a DB server other than Exchange, but you mentioned two EHR servers. Is one of them a DB server? If so, what DB? How many users on your EHR? RDS (terminal server is the old name)?

                      I would go with RAID 5 SSD's 1TB capacity.

                      The price per GB is more expensive but you'd be gaining all of the benefits of SSD storage.

                      You could go with RAID 10 2TB Drives but would need more disks to achieve your storage goals. Which might out weigh your cost-goal.

                        Moving from local disks to local USB and/or SD card is pretty easy since it is a fresh install combined with moving the settings over. ESXi is not stateless, but nearly so. So moving between media is not difficult.

                          He might not really gain any benefits if his IOPS are very low.

                            I'm starting from the top so might have missed details, but disk size is selected but not type, RAID level or spindle count? Those all have to be decided as a single, holistic decision based around speed, risk and cost needs.

                            What are the capacity, performance and cost needs for this?

                              Yes, figure out your IOPS needs, business needs and budget before coming up with a solution. Don't make the solution before you've determined the needs.

                                Moving to local disks makes sense now that a purchase needs to be made. The SAN is negative in all four areas: cost, capacity, performance and risk. So adding to the technical debt there would be bad.

                                    It's not just cost but loss of features and extra license management work for you. VMware is not just a price negative.

                                      You can do a lot with eight bays. Sixteen really gives you flexibility.

                                        Drat - I forgot to go back and mention this.

                                        Why pay one penny if it gains you nearly nothing or nothing. Sure you're more familiar with it now, but really Hyper-V is pretty easy and straight forward... and offers no road blocks to features you might want to use in the future.

                                          You aren't even at "Standard Availability" today, you have low availability (quite a bit less reliable than just a single server) so if you need HA your current setup wouldn't have been an option. Even if you needed the reliability of a stand alone server what you have today is not there. So either you don't need either SA or HA, or your current situation is not meeting your needs and that needs to be addressed as well.

                                            There are two decent choices going forward....

                                            • Move to standard local storage. This will move you just from LA (low availability) to SA (standard availability) while being the cheapest solution. There are two ways to tackle this:
                                              • Going to all local storage on a single server
                                              • Going to half of the needed storage on each server and splitting load
                                            • Move to replicated local storage. This will move you towards HA at the platform level (and only at that level, this doesn't actually give you HA unless you do everything else needed for HA too) but doubles the necessary investment in storage AND requires that you buy much more expensive licensing from VMware. The licensing would be free from any platform other than VMware.
