easyRAID Q16+U4R3
High Performance SATA-II to U320 SCSI RAID
with RAID 6 and Triple Parity

The easyRAID Q16+ series RAID system is an important milestone in RAID technology. Approaching critical high-end enterprise demands, redundant upgradable single controller designs require complete and flexible choices for different storage environments. The easyRAID Q16+ features an Intel i80331 CPU, 2xU320 VHDCI SCSI hosts, and fully modularised components that enable the least amount of operating downtime and maintenance.

The Q16+ features the innovative RAID level TP, which enables extremely advanced data protection by allowing three multiple hard drives to fail during operation.

Powerful hardware design, highly scalable expansion, and a user-friendly management interface makes the easyRAID Q16+ the best choice for fault tolerance, performance driven solutions.

The easyRAID Q16+ is designed to simplify complicated and time consuming operations. Compared to the conventional disk array, which is designed for experienced IT professionals, easyRAID comes with the innovative Plug-N-Play RAID. Just attach to your host server and easyRAID is up and running after following the step-by-step built-in setup program and a user interfaced button on the front panel.

The high availability hardware and firmware architecture automatically detects bad sectors and failed disk drives. When installing a replacement disk or using a hot spare disk, the system automatically rebuilds data without keyed in commands or functions.

An LCD panel Display a comprehensive operating status. Upon failure (HDD) the built in buzzer sounds and LCD panel indicated the failure status simultaneously. With the system on, remove and install hot swap components without interrupting data access.

The easyRAID series RAID is completely operating system independent and transparent with Windows based OS, Linux, Novell, UNIX, or Mac based servers.

Advanced RAID features

Disk Self Test (DST) – Before the release of this function, users of RAID systems were forced to test suspected bad hard drives in a host computer individually using a drive manufacturer’s utility. This function tests the health of hard drives with them installed in the RAID unit. DST performs write tests, servo analysis, and read scan tests; the test results are then displayed on the LCD and hyper terminal output. This can aid the user in deciding whether or not to replace a suspected failing hard drive. We highly recommend running this test before initializing a RAID set to ensure a healthy RAID solution.

Disk Scrubbing (DS) – With today’s RAID subsystems being capable of storing multiple terabytes, it is becoming increasingly difficult to manage and maintain that large amount of data. To aid a user in maintaining their data’s health, easyRAID has released their newest firmware function Disk Scrubbing. The data and/or parity stored on hard drives can sometimes become corrupted; this data can also reside in areas that are not accessed for long periods of time. DS will use idle time to test the disks, and if a sector is found to be corrupted, the data will be regenerated from other RAID member disks and will be written to an uncorrupted sector. The purpose of DS is to prevent the possibility of having multiple corrupted sectors in a single stripe, which is one of the main causes of data loss.

Disk Cloning (DC) – Hard drives are the most likely component to fail in a RAID array, and almost impossible to predict when the failure will occur. When a failure does occur the RAID unit will have to regenerate data from the non-failed hard drives to rebuild a new drive, and the RAID array will be in degraded mode. Having a unit in degraded mode is a very cautious time because if a second hard drive was to fail the RAID is destroyed and data is lost. This is where Disk Cloning can aide a user. With the help of the hard drives built in S.M.A.R.T. function, DC can determine when to begin cloning a bad drive to a hot spare. Upon completion of cloning, the new cloned disk can take the position of the failing disk or can stand-by until the original disk fails, then take the failed disks position. Disk cloning is to prevent a rebuild from ever occurring and having the unit in degraded mode.

RAID level TP: “Disk Striping with Triple Distributed Parity”

Similar to Raid 5 and 6, Raid TP stripes data across drives, but calculates for three parities that are written to three individual disks.

Raid TP uses three indepdendent equations to calculate each individual parity that enable reconstruction of data when three disks and/or blocks fail at the same time.

Raid TP adds an extra level of redundancy to help protect your data.
