FUJITSU PRAID EP540i

RAID Controller SAS 12Gbit/s 4GB cache based on Broadcom MegaRAID® for internal storage devices

The RAID concept (Redundant Array of Independent Disks) refers to several independent hard disks which form a large logical drive when switched together. Redundancy information is calculated from several data blocks (except for RAID 0) and saved distributed to the individual hard disks. Your operating system no longer accesses the individual hard disks, but the array. The actual objective of the RAID concept is to increase availability and prevent downtimes in the event of a hard disk failure. However, the theoretical security of the RAID concept is only as good as

the RAID controller used. Benet from the Fujitsu

RAID controllers where technology, experience and practical implementation all ensure the security that your company needs in the event of an emergency.

PRAID EP540i

The Fujitsu RAID Controller PRAID EP540i with 4GB cache and16x12Gbit/s SAS ports improves performance for storage intensive workloads such as databases and sets new speed and data security standards for internal storage drives. The new PRAID EP540i supports up to 16 SAS/SATA drives, up to 4 NVMe PCIe drives or a mixture of SAS/SATA and NVMe drives. NVMe is an interface with lower overhead, lower latency and drastically increased bandwidth and IOP’s. The RAID stack is based on the Broadcom MegaRAID® and offers high data throughput, a comprehensive fault tolerance

function and user-friendly management options. Moreover, the Controller management is integrated seamlessly into the Fujitsu server management concept. All controller functions are supported by the Fujitsu ServerView RAID Manager. The PRAID EP540i is designed for 3, 6 and 12Gbit/s SAS as well as for 3 and 6Gbit/s SATA drives.

Regardless of the drive speed, it delivers signicant

performance improvements in both read and write

applications. The controller rmware also supports

FastPath® without an additional license. FastPath®

accelerates the use of SSD only congurations. The

RAID controller supports all of the important RAID

levels including RAID 6 and 60. The optional ash

battery backup (FBU) combined with the already included TFM module ensures the integrity of the data stored in the cache on the RAID controller in case of a power outage. In this event, the data will

be copied to a non-volatile ash memory (TFM).

The TFM module is bundled with the controller, the FBU is optional. Important information for later upgrade from or

downgrade to std. SAS controller: Specic cable

sets per system can be required as L-Part, please

refer to Paper Congurator, order tool or controller

and system documentation. Orders ex factory are

congured with appropriate cables.
