Overall Satisfaction with IBM System Storage DS8000

We use IBM DS8000 to support all of our mortgage servicing customers on the mainframe. The DS8K was chosen for its performance, reliability and synergy with IBM zSeries. The DS8k is also important in reducing risk. The capabilities in replication and disaster recovery are unmatched in the industry and allow us to utilize complimentary technologies such as GDPS for resiliency.
  • Performance, the DS8k has provided excellent levels of service levels. I/O response time is no longer a concern.
  • Scalability - as we grow the platform, performance has been steady.
  • Replication - copy services capabilites are vast and ensure data integrity and consistency.
  • Ease of use, the latest GUIs have vastly improved over the last 5+ years. The GUI is a great learning tool for support teams not familiar with the DS8k.
  • Ability to use advanced features on HMC (for customers).
  • Provide better integration with GDPS - for example GDPS GUI hosted on DS8k HMC
  • Allow customers to install firmware
  • Ability to retain the machine past its depreciable life
  • Performance is steady as machine scales upward
  • LDAP Security setup not well documented
Other vendors lack many of the mainframe functions provided by DS8k. SInce IBM is the most prominent maninframe vendor support is unmatched.
Well suited for mainframe CKD based applications. There is unmatched synergy with IBM zSeries when compared to the competition, for example zHPF, SUPERPAV, zHyperLink, cache management and replication technologies. For distributed, the fact that Copy Services Manager comes with the box is a great move on IBMs part to provide replication capability no matter what the applicaiton. I think the DS8k is less suited for smaller distributed environments. I think product overlap with V9000 in this case.
