Only DR/VFI has Tape Stacking as a standard function - to identify critical tape data and stack the data by application.
|
|
|
Thousands of tape cartridges holding a few feet of critical application data wastes tape library space, mount time and, most importantly, strains your DR shipping response if a disaster occurs. Tape Stacking is the obvious answer to this problem.

|
|
Everyone says they are capable of doing Tape Stacking, but only DR/VFI has Tape Stacking as a standard function of Tape-Assist to identify critical tape data and stack the data by application in a flexible and logical manner.
|
|
-
Tape Stacking is defined as putting multiple datasets on the same physical tape to exploit the large capacities of current tape cartridges.
-
Critical tape data is identified by application in DR/VFI allowing you to stack tapes logically, by application.
-
The stacking options allow stacking
- no data
- all data or
- everything but datasets that are already multi-volume and/or
- tapes that already contain multiple datasets
|
|
|
The intelligence of the DR/VFI process helps insure that an application’s programs will not concurrently be using different datasets on the same tape avoiding the problem of "deadly embrace".
|
|
| DR/VFI with Tape-Assist provides significant advantages. |
|
| DR/VFI reduces tape copy operations to their bare essentials. |
|
| DR/VFI tells you which tapes are critical to critical applications and that can be as little as 10% of your total tape copy volume. |
|
| Tape-Assist avoids unnecessary tape copies at the DR site and includes Tape Stacking to reduce the number of tape cartridges while stacking data logically by application. |
