With the B120i controller, I can add 4 drives to it. The drive bays hold 4 drives. Do I need to purchase anything else to connect 4 drives up?

I purchased a Ml310e last year with the four port LFF hot swap cage. I don't know what controller is on that array, so I'll answer in the context I know. Unless HP has changed it's policy or you purchase media from HP, you will need to purchase drive trays so you can install drives in a slot. The unit does not come with them. At the time I purchased the server, I didn't know this and wound up spending about three times as much for media, HP drives are commercial grade and expensive, as I intended for a lab server. At that time, OEM trays could not be purchased and HP didn't offer them without a drive installed. Recently, I've found a tray that the vendor says fits the 310 LFF slot for about $40 per tray. I have not yet tried one but will in the next few months as I upgrade the server. Interestingly, when I purchased the server, OEM trays were available for the SFF slots but the server with those was not necessary and didn't fit my budget. Because of that issue, I would not have purchased another 310 because of the media cost, but will reconsider if the trays work. It is a well designed piece of hardware, but having to use HP media increase the cost of how I wanted to configure the storage from $300 to $1500 so I had to acquire less capacity for greater cost and didn't get to use a SSD for my system's hypervisor drive.

You can add drives as you need them. The drives can be of mixed sizes too for the hybrid raid configuation; however, I recommend you try to keep to one drive size so select your initial drives with the thought of expanding later.

I do believe that you need both cables to get all 8 drives. I think it is 4 per but I have not tested as I only have 4 drives at this time.

SAS RAID controllers allow using SAS expanders to increase the amount of ports that can be hooked up to the controller. For example, SAS controllers have two 4 port channels. Hook one up to this SAS expander and now you have 5 additional 4 port channels to hook up hard drives. They also can be daisy chained. Many controllers allow up to 128 drives per controller (and they can be SAS or SATA disks). Think of it as an network switch but for SAS controllers.

I do not know--this was so unreliable I have stopped using it. It did not matter what drives I used--none would stay connected. Also, realize you can only use one at a time.

You can start with one drive and add drives as needed. Of course if you don't use at least 2 drives you can't RAID them. The NAS will pick an appropriate RAID configuration automatically, but you can override it if you like. You can even mix disk sizes but that is not the best solution. You should use SATA 6 drives. As you add new drives the system recognizes them and reconfigures your system.

Hi, that depends on the configuration of your drives, if it raid 0,1 or 5, then it should see as a single drive, else, it wont be possible to see all the drives

Although I haven't done it with this particular array (I'm using it in RAID5), by the regular principals, it doesn't look good. If they were individual drives, absolutely not. If they are removed from another JBOD, they would have to be in the same order, and would depend on having the same firmware. Basically... I wouldn't try it with any array. What you're looking for is probably something with a port multiplier in it so that each drive is handled individually by your OS. Then you'd need a port-multiplier compatible eSATA card (or usb if you like slow drives).

I just used two...one powered the first three buttons and the other powered the other three. You can use either the 4 pin (ATA) or the SATA. If you are only doing two drives....just hook up one side (either 1,2,3 or 4,5,6).

It came with 4 with mine sata drives but it might be different with your configuration

It comes with the brackets to install all 4 drives, as to any hard drive I am not sure. They have a list of tested and recommended hard drives, there are a lot of mfgs and models. You also want to install in matching pairs at least and possibly all4 the same if you want to use certain RAID structures.

I suggest you use one of the HDD slots becuase there are a lot, and you connect SDDs and all other parts to the mobo. Hope that helps!

Yes it does operate with 2, 3 or 4 drives. As you add more drives you have the option to switch to higher RAID configurations.

I asked Oyen Digital Tech Support this question (they are very responsive). This was their reply: "If a 3-drive RAID 5 set is created, and a 4th drive is added later, it will be a hot-spare drive. The Mobius does not have the ability to add the 4th drive to the original 3-drive set. The only way to accomplish this is to clear the original RAID and recreate a new 4-drive RAID 5 set." Back to me. Another option is to use software RAID. You would put the enclosure in JBOD ("Just a bunch of Disks") mode, and create your 3-drive RAID set with the software. Then when you add a 4th or a 5th drive it will either be treated as an independent drive, or can be part of yet another RAID set.

This is an expansion unit, that allow you to add up to 12 more drives to DS2413+ or DS3612xs. This expansion unit, by itself, does not do anything.

Their is no problem with mixing various size drives. I did that until I eventually updated to all 4th drives.

I've used it for 9 DVD-Roms\Blueray drives just fine. You will have slowdown if they're all running at once, but I never had them drop like with other hubs.
