Found this great whitepaper regarding changes in the selection of direct attached storage in the new Gen8 servers… Find the document here.

Abstract:

HP ProLiant Gen8 servers embody more than 150 design innovations. By engineering ProLiant Gen8 servers for enhanced solid state performance and by adding intelligent algorithms and analytics to manage performance, resiliency, and data protection in real-time, we made ProLiant Gen8 servers an all-in-one platform optimized for your storage workload demands.

The direct attached storage (DAS) solution you choose for your systems affects their performance, cost, and usability. To find the best solution for your environment, you should take into consideration interconnect technology, controller technology and features, as well as drive types and configurations.

This technology brief discusses all these considerations for direct attached storage to HP ProLiant Gen8 servers. Note that we include multiple types of DAS:

• Storage that connects directly to the drive controller or through an expander to the drive controller

• Storage within the server chassis or in an external chassis
