According to the pro license you can have 28 data,2 parity,24 cache drives. That would be a total of 54 drives on an unlimited license which could only handle 30 drives.  So are the 24 cache drives not considered part of the storage array?

It has nothing to do with "considered". Cache is not part of the array.

The key difference is the cache pool uses btrfs RAID (if more than 1 device) while the array is "Unraid", which is literally not RAID.

 

I believe the "only" 30 drives limit is to prevent people from going Linus-style overboard. If you need more than 30 drives, you are better off with an enterprise-grade product i.e. not Unraid.

EDIT:  I should add one thing here 'Attached' means installed and connected devices.  (If the device has power and a SATA connection, it is an attached device! )  I understand that you can plugin a USB device after the system is running and that would not count as an attached device.

Does that mean I can go with the basic license since cache drives don't factor into the storage array?

ALL drives connected to the PC count regardless of whether Unraid is using them or not.

According to this post optical drives do count against your attached devices storage.

It's not correct, they don't count, they might have at some point in the past.

I'm just trying to figure out if I should go 5 Data,1 parity,1 cache or 5 data,1 parity,no cache or 4 data,1 parity,1 cache.  I see a lot of reports saying a cache drive is a good idea & some saying not necessary.  The chassis I'm using is the Norco RPC-2106.  It has 6 hotswap bays & 2 5.25 bays.  Just trying to figure out if I want more storage or adding a cache drive.

@chipmaster , If you are within one drive of being  over the max for a Basic license, allow me to suggest going for the Plus license.  If you are like most of us, you will be buying it soon in any case. 😏  So save the $9.00US upgrading fee.

I'll be building a second server with 11 data drives,1 parity,no cache drive.  This server would be primarily storage & running plex.  So a plus license makes sense to get.  The first one I'm building is more for ripping & encoding blurays & also running docker containers.

A drive not in the parity array is a very good idea, and cache is the simplest way to accomplish that. Whether as cache or not, that non-array drive counts against license.

 

You need a drive out of the parity array to install dockers or VMs, or they will have their performance impacted due to the slower parity writes, and they will keep parity and array disk(s) spinning.

I also just found out that if using an optical drive it counts as storage.  So I have to get a 12 drive license for my setup.

just go pro, one time fee and updates are free!

Cost saving proposal for you: merge both of them into 1 server. I don't see why Plex + ripping + storage can't be done on the same server. In fact, rip -> store -> stream is not an unusual workflow for an Unraid server.

The chassis I’m using is a 6 bay hotswap & 2 5.25 drivebay enclosure.  It’s going to be a 6 core 12 thread AMD Ryzen cpu.  The second server is going to be a 12 drive chassis.  I haven’t found a 12 bay chassis with a 5.25 drive bay
