      Dell PowerEdge C2100 2.5" Chassis with up to 24 Hard Drives plus 2 2.5" Internal Hard Drives.

      Is that 24 2.5" drives?

        The only configuration those come in are 12x 3.5" or 24x 2.5"

          OK that's what I thought. The description on the site is a bit misleading.

          Thanks for the clarification.

            Yes, 24x 2.5" and no hardware RAID. Remember that Dell C systems are not for SMBs but for huge enterprise clusters, just like HP DL1xx series. These are designed to be throw-away nodes, not stand alone enterprise servers. What is your use case for looking at something other than the PowerEdge R series?

              Backup storage for the virtualization project you're aware of.

              Just calculating what I might need to put something in a colo if the conversation comes up.

              All storage space included (C: Drives and shares) Looking at 5841 GB.

              To do full backups using NAUBackup (weekly or 4 times a month) we'd need 23364 GB of storage.

                The 5841 GB is "used" space.

                Space that's on the each drive regardless if it's 100% used. (none are) But just trying to do the math on this.

                  Exactly where "throw away" servers are a horrible fit. You don't want equipment designed to be replaced, rather than replaired, in a colo where the cost to get gear in and out is high.

                    You already know that the 2 TB drives are going to cost you $400 ea at that size. Sure this is the way you want to go?

                    If you move to 3.5" drives you can move up to 6 TB drives. Assuming you can do consumer drives, you're looking at approx $200 a drive for 3 times the storage.

                      Why use a "disposable" server with high cost enterprise drives instead of an enterprise server with consumer SATA drives? LFF SATA is so much cheaper per GB, perfect for backup systems.

                        Just spitballing the idea's and it was the first device I came across. 3.5 SATA would work as well.

                        Should I be more concerned about URE's (etc) on consumer SATA's at this sort of setup?

                          This would only be for off-host backup, but written to weekly if my plan is decided on.

                            Not including the incrementals which are written ever hour, stored for 72 hours and then dumped.

                              Depends on the RAID level that you decide to use.

                                Spinning rust, RAID 10 of course.

                                  But it is not a viable device, so any information about it is misleading. Only use viable devices, even when spitballing.

                                    Then no, UREs are not a factor.

                                      What makes it non via? I'm assuming you can add a RAID controller?

                                        Everything about a C series is designed to be disposable. Everything. Non-redundant parts, cheaper parts. This is literally a disposable node design, like a BackBlaze POD. This is designed exclusively for situations where you have many redundant nodes and you don't care if one or two just die on you.

                                          Cheap for a reason. The C stands for Cluster.

                                            As in Cluster F*** I'm guessing then.
