asus ds300fG2 overvIew
All ASUS Storage ASUS DS300f G2 and DS300j G2 models support use of 6 Gb/s SAS and SATA disks.
The DS300 G2 models are coupled with high speed 8 Gb/s Fibre Channel host connectivity and 1 Gb/s iSCSI
host connectivity.
The ASUS DS300f G2 model is coupled with high speed 1 Gb/s iSCSI host connectivity.
Performance
The ASUS Storage ASUS DS300f G2 is built using a 64bit 6-core processor per RAID controller, and support for
6 Gb/s SAS and SATA hard disk drives and solid state drives (SR1). Dual active-active controller modules with
cache mirroring over a PCIe Gen 2 link allow for redundant data paths to ensure data availability while dual power
supply/cooling units minimize downtime and any disruption to business continuity.
GreenraID
ASUS Storage cares about the environment. ASUS DS300f G2 products utilize environmentally friendly production
methodsandmaterialsandaredesignedwithhigh-efciencyinmind.Poweredby80Pluscertiedpowersupplies
thatofferupto85%powerefciency,allASUSDS300fG2devicesimprovetotalcostofownershipbyconserving
power, reducing heat output and improving cooling costs. Additionally, the ASUS Storage as GreenRAID story
includes advanced power management support for hard disk drives providing up to 65% energy savings.
ServIce anD SuPPort
Every ASUS DS300f G2 subsystem is backed by the ASUS Storage Three-Year limited warranty with 24-hour,
7-day English language telephone and e-mail support. In addition to our industry leading warranty, ASUS Storage
offers extended warranty and onsite parts replacement options with service levels with response times as low
four hours.
new featureS In the aSuS DS300fG2
Perfectrebuild™
ThePerfectRebuild™featureisaninnovativeapproachtorebuildingaRAIDarrayinordertosignicantly
reduce the amount of time needed for completion. This frees up CPU resources more quickly to be available for
I/O and other demands. PerfectRebuild™ ignores any portion of the logical drive where no write changes have
occurred, focusing only on the parts that have changed. The conventional approach has been to rebuild the
entire logical drive, even sections with no write changes. This reduction in the total time needed for a rebuild
isespeciallysignicantforverylargedrives.
AdvAnced bAttery flAsh bAckuP
Use the optional Backup Battery Unit (BBU) and Flash modules for maximum data protection in the event of
power loss. High performance RAID arrays operating in write-back mode present a write loss risk in the event
of a power loss. Since data is considered committed as soon as the controller has received it in cache memory,
it will be lost if power is interrupted. The conventional solution is to use a BBU to maintain the RAID cache
for 72 hours. A better solution is to use power from the BBU to write the content of the RAID controller write
cachetonon-volatileashmemoryinordertoextendtheperiodofcacheprotectionbeyondthestandard72
hours provided by a typical BBU.
hArd disk cAche Protection
HD Cache Protection is another capability available for use with high performance RAID arrays that employ
the optional BBU and USB Flash modules. HD Cache Protection uses the BBU and USB Flash modules to protect
against loss of HDD cache data, eliminating the need to add an expensive universal power supply (UPS). The
HDDcacheiswrittentoashmemory,again,usingpowerfromtheBBUinordertoprotecttheHDDcache
beyond the standard 72 hours.
