Hardware requirements for restoring user data with this function at the disaster recovery site are explained below.
Because data is transferred from the operation site to the disaster recovery site using portable media (DAI etc.) that store TSM related files described in "14.5.1.2 Saving TSM related files, the tape server at the operation site and that at the disaster recovery site must be able to access the same portable media.
Environment | Target | Hardware resource |
|---|---|---|
Operation site | Tape server | Portable media access device |
The disaster recovery site | Tape server | SUN server with Solaris installed |
Portable media access device | ||
Storage server | A server of the same platform as that of the storage server that is to process the data to be restored from the operation site | |
ETERNUS storage system/ETERNUS tape library | Hardware as described in "Hardware Requirements" in the "ETERNUS SF AdvancedCopy Manager Installation Guide". The ETERNUS tape library at the disaster recovery site must be able to read at the tapes used in the backup process at the operation site. |
