Space Recovery System (SRS)  
 

Overview
The Space Recovery System (SRS) eliminates all types of storage space-related errors. Whether the error is caused by application growth, out-of-date JCL, volume space fragmentation, or job conflicts, SRS steps in to dynamically modify space needs, find available space, and prevent failures. SRS not only improves system throughput, but provides a critical “safety net” that allows installations achieve higher rates of disk space utilization than could ever be accomplished in any other way.

 
     
 

Eliminate B37, D37, E37 abends and VSAM errors.
SRS determines in advance when an out-of-space condition will occur and prevents the error. Production downtime and reruns due to space problems are eliminated.

Support for all types of data.
SRS can prevent problems for all types of datasets, SMS-managed or non-SMS, VSAM or non-VSAM, striped, extended-format, HFS, and others.

Automatic Reorganisation of Multivolume Datasets.
SRS can prevent problems for all types of datasets, SMS-managed or non-SMS, VSAM or non-VSAM, striped, extended-format, HFS, and others.

Catalog and Tape Error Prevention.
SRS does more that just prevent DASD space errors. Duplicate dataset name and NOT-CATLGD-2 errors can be stopped, S837-08 tape errors can be eliminated, and output datasets can automatically be switched to tape units with non-empty automatic cartridge loaders.

Extensions allow better control over space use.
The SRSE function allows installations to automatically route desired datasets to VIO, limit dataset space requests, add RLSE parameters, choose optimal tape and disk blocksizes, and control other aspects of dataset usage.

 
     
 
   
   

A recent study found that over the life of the DASD, the cost to manage that storage could be almost three times it's original cost...

Decisions, Decisions...

Deciding how to set your DASD utilisation threshold is not easy:

   High = Space Abends
   Low = Waste Resources

   Demand tends to be cyclic
   Users are poor at estimates

DASD growth
DASD growth of 30% annually has almost become expected. With this level of continuing growth it is essential that you ensure that this large investment of capital is well spent.

The industry average DASD utilisation remains near 70% but would be a lot higher with the right tool to manage it.

SRS helps
Implementing SRS helps to increase DASD utilisation because SRS can:

   Recover from Space Abends
   Handle unpredictable demands
   Overcome OS/390 allocation limitations
