The adapters have two internal mini-SAS connectors to control up to 32devices and support global and dedicated hot-spare drives. The ServeRAID M5014 controller delivers a fullRAID 6 Gbps SAS 2.0 solution, while the ServeRAID M5015 provides additional performance advantages ofan extended cache and a standard battery backup unit. With the attachment of the ServeRAID M5000Advanced Feature Key, the ServeRAID M5015 and M5014 offer the option of RAID 6, RAID 60, and SEDEncryption Key management.Figure 1 shows the ServeRAID M5015 with its standard battery backup unit.Figure 1. ServeRAID M5015 SAS/SATA ControllerDid you know?6 Gbps SAS 2.0 technology has been introduced to address data off-load bottlenecks in the direct-accessstorage environment. This new throughput doubles the transfer rate of the previous generation. SAS 2.0 isdesigned for backward compatibility with 3 Gbps SAS as well as with 3 Gbps SATA hard drives.Self-encrypting drives are based on a new technology that helps prevent data from being accessed withoutauthorization. These drives adhere to the Trusted Computing Group (TCG) Enterprise Security SubsystemClass specification and are National Security Agency qualified to provide government-grade encryption.With self-encrypting drives (SEDs), if a drive is removed from its storage system or the server that it ishoused in, the data on that drive is encrypted and useless to anyone who attempts to access it without theappropriate security authorization.ServeRAID M5015 and M5014 SAS/SATA Controllers 1
