Fujitsu PRAID EP540i FH/LP RAID radič PCI Express 3.0 12 Gbit/s

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. Benefit 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 significant performance improvements in both read and write applications. The controller firmware also supports FastPath® without an additional license. FastPath® accelerates the use of SSD only configurations. The RAID controller supports all of the important RAID levels including RAID 6 and 60. The optional flash 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 flash 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: Specific cable sets per system can be required as L-Part, please refer to Paper Configurator, order tool or controller and system documentation. Orders ex factory are configured with appropriate cables.

Fujitsu PRAID EP540i FH/LP. Supported storage drive interfaces: PCI Express 3.0, Host interface: PCI Express. RAID levels: 0, 1, 1E, 5, 6, 10, 50, 60, Data transfer rate: 12 Gbit/s, Channels quantity: 16 channels

How to use

Install the PRAID EP540i into a compatible PCI Express slot on a Fujitsu server following the system and controller documentation. Connect the appropriate SAS/SATA or NVMe cabling for the target drive configuration; note that specific cable sets may be required for certain systems and that factory orders are shipped with appropriate cables. Configure the RAID array and cache settings using Fujitsu ServerView RAID Manager or the MegaRAID management utility, select the desired RAID level, and initialize the array. If using the optional FBU, install and configure it so the TFM module can copy cached data to non-volatile flash in the event of power loss.

Recommendations

For upgrade or downgrade between this controller and a standard SAS controller, verify required cable sets per system (may be L-Part) in the Paper Configurator or controller/system documentation before ordering or performing hardware changes.
