Depending on your country, you can find many third-party providers of replacement EMC drives. I do not recommend, however, buying drives off Ebay. In my experience, some drives are mislabeled, even to the point of the incorrect (even fradulent) pictures.
Find a reputable dealer in your region and they should be able to quickly quote a spare for you. You can always start with some of the larger US-based companies, then find their international counterparts.
On the CX300, you take an unused disk, create a single disk raid group, then create a Hot Spare. When a disk fails the hot spare will take over for the failed disk (rebuilding the hot spare from the raid type of the raid group that owns the failed disks).
You can click on Help and search for Hot Spare for more information.
Looking in the Help/Hot Spare I found the following definition:
Hot Spare (global spare) - A simple disk that serves as a temporary replacement for a failed disk in a RAID 5, 3, 1 or 1/0 RAID LUN. Data from the failed disk is reconstructed automatically on the hot spare from the parity or mirrored data on the working disks in the LUN, so the data on the LUN is always accessible.
How can verify if the failed disk has been reconstructed automatically ?
The Hot Spare is replacing the failed disk - you can now remove the failed disk and replace with a new disk. Make sure you pull the correct disk - the numbering in the DAE starts with disk zero on the left - there should also be markings on the DAE identifying the disk.
When the new disk is inserted it will begin the "equalizing" stage - copying the data from the hot spare to the new disk.

My configuration is :
Bus 0 Enclosure 0 15 disks
Bus 0 Enclosure 1 10 disks
Raid Group 0 [Hot Spare] - (Bus 0 Enclosure 1 Disk 9)
Raid Group 10 [Raid 5] - (Bus 0 Enclosure 0 Disk 0,1,2,3,4)
Raid Group 20 [Raid 5] - (Bus 0 Enclosure 0 Disk 5,6,7,8) (Bus 0 Enclosure 1 Disk 4)
Raid Group 30 [Raid 5] - (Bus 0 Enclosure 0 Disk 9,10,11,12)
Raid Group 40 [Raid 1] - (Bus 0 Enclosure 0 Disk 13,14)
Raid Group 50 [Raid 1_0] - (Bus 0 Enclosure 1 Disk 0,1,2,3)
Raid Group 60 [Raid 5] - (Bus 0 Enclosure 1 Disk 5,6,7,8)
The Bus 0 Enclosure 0 Disk 11 is currently in FAULT.
The process to assign the spare disk is automatic or is it necessary to do manually ?
Do you know where is possible to buy an EMC disk 146GB 10K (part number: EMC 005048807) ?
Thanks in advance, Edgardo

Let us know if that helps!

I tried to read Help/Hot Spare, but I don't undertood how to do exactly.
I have the Disk 9 in the Raid Group 0 and the faulty Disk 11 in the Raid Group 30.
How can assign the Disk 9 to the Raid Group 30 ?
What happens if another disk of the Raid Group 30 fails ?
Thanks, Edgardo

I analyzed the status of the Hot Spare Disk 9:
in Properties - General the line Hot Spare Replacing reports: Disk: 0-0-11
This means that the faulty disk 11 has been replaced by the Hot Spare disk.
Could you confirm me this issue ?
