DDN EXAScaler vs. IBM Storage DS8000

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

Incentivized

• Remote Copy -- The DS8k has decades of excellent code built to handle the most demanding environments for mainframe or open systems and can be combined with automation solutions like GDPS or Copy Services Manager
• Reliability and Availability -- This is the platform that gets used for the most demanding environments, even when FICON attachment isn't required
• Continued enhancement -- IBM continues to put resources into the DS8k and the platform has advanced with the technology from z and power
• Mainframe synergy -- Poughkeepsie communicates and works very closely with the DS8k developers

Incentivized

• The DS8000 family still lacks deduplication and compression algorithms.
• For best results on replication enablement, optional Copy Services Manager is suggested.

DS8882F provides CKD storage in a manageable footprint. Its advantage over FlashSystem is its interoperability with IBM Z Systems

• I do not know the cost. If it prevents future system wide outages, it will be a great ROI for our company.
