To use this software, you need to obtain a trust-based
license and then download the installable software package.
Procedure
-
Go to the IBM®
Passport Advantage® website to obtain a
trust-based license for
IBM Spectrum Virtualize
.
-
On the website, follow the directions to enter your IBM customer number (ICN) and the maximum number of terabytes of
virtual storage to provision with your systems.
-
Download the installable software package from the same IBM
Passport Advantage website.
What to do next
- Differential licensing
- Differential licensing is the term used to refer to the measurement of virtualization and
compression licenses, where different types of storage are charged at different rates.
Differential
licensing uses a storage capacity unit (SCU)-based license scheme for virtualization and compression
licenses. For each SCU, a client is entitled to manage different amounts of usable capacity based on a
storage category classification. Table 1 identifies
the storage categories and SCU ratios for each category.
Table 1. Storage capacity unit categories and ratios
| Storage category |
Included storage types |
SCU ratio |
| 1 |
Flash and solid-state drives (SSDs) |
1 SCU equates to 1.00 TB usable of Category 1 storage |
| 2 |
Serial Attached SCSI (SAS) drives and Fibre Channel drives |
1 SCU equates to 1.18 TB usable of Category 2 storage |
| 3 |
Nearline SAS (NL-SAS) and Serial ATA (SATA) drives |
1 SCU equates to 4.00 TB usable of Category 3 storage |
- Table 2 provides an example of how SCU licensing
might work based on category types.
