FUJITSU PRAID EP400i / EP420i

RAID Controller SAS 12Gbit/s 1GB or 2GB cache based on LSI 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 EP400i / EP420i

The Fujitsu RAID ControllerPRAID EP400i with 8
ports sets new speed and data security standards for
internal storage drives. The RAID stack is based on
the LSI 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 EP400i is
designed for backward compatibility with 3Gbit/s
SAS as well as with 6Gbit/s and 3Gbit/s SATA hard

drives. Regardless of the drive speed, it delivers

signicant performance improvements in both

read and write applications. Due to the support
of 64-bit addressing, a robust set of RAID features
and demanding error tolerance functions the
controller provides high RAID performance and data
availability. Powerful online management service
programs (Fujitsu ServerView RAID Manager),
which are simple to operate and quick to install,
provide the administrator with unparalleled

exibility and access to the arrays. The RAID

controller supports all of the important RAID levels

including RAID 6 and 60. The optional ash battery

backup (FBU) combined with 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 FBU provides a low-priced

alternative to an uninterruptible power supply
(UPS) and, when compared to battery backup up
units (BBU), enables a long-term, secure store of
data and better serviceability. Always select FBU
and TFM module in combination.
The Advanced Software Options in combination
with Solid State Disks in front of HDD volumes can
create high-capacity,high-performance controller

cache pools, depending on the load prole. A free

of charge test version is available at PRIMERGY-PM.
