What's new


- Up to a 24% performance improvement on EVA4100/6100/8100 arrays.
- Better capacity management and storage provisioning with new LUN shrink and growth.
- Improved reliability and availability; HP's data shows that most customers are achieving 99.999% availability with the EVA 4x00/6x00/8x00. Following HP's EVA Availability Best Practices can help customers achieve this result.
- EVA4100/6100/8100â s new point to point shelf provides a fully switched backend and redundant paths from the controllers to the disk for high data availability.
- Integration with HP Storage Essentials Standard Edition to affordably manage small to medium EVA and SANs.


IMHO the most important is the point to point connectivity.
