easyraid Q16PS RAID system with 3 x 16 bay expansion JBODs



Features
  • Innovate New Array Structure
    The easyRAID Q16PS series features a new innovate array structure that hierarchically organizes storage objects. With this structure, physical drives are combined into Disk Groups (DG). Disk Groups are subdivided into Logical Disks (LD) where arrays are created. Lastly, Logical Disk can be combined or stripped together to form Volumes. Either volumes or LD can be pointed to a LUN which are then presented to the host computer.
  • Online Expansion and Defragmentation of Disk Groups
    New physical disks can be added by expansion of a Disk Group (DG) while the unit remains online. During the process of expanding Disk Groups, defragmentation can be selected to move unused capacity to the ending LBA of a Disk Group. Defragmentation can also be selected at anytime there is unused storage space residing between Logical Disks.
  • Online Expansion and Shrinking of Logical Disks
    Logical Disk (LD) Online Expansion can increase the capacity of an online LUN, instead of having to create a separate partition for unused capacity or capacity gained from Disk Group Expansion; now your storage can dynamically grow as your demands grow. In the event of overestimating requirements for Logical Disk capacity, shrinking can be used reduce the allocated storage of a Logical Disk.
  • Web-based GUI
    An embedded CGI-based GUI (graphic user interface) management interface can be accessed through a web browser. The GUI allows users to easily setup RAID arrays, lun mapping, etc. and also provides remote monitoring of drive health, fan, and power supplies.
  • RAID 6
    RAID 6 improves over the industry standard RAID 5 by adding another parity disk which gives greater reliability and data protection.
  • Array Recovery Utility
    The easyRAID Q12PS series now provides an Array Recovery Utility (ARU) that can aid a user in the event of multiple drive failures corrupting the RAID array of a Logical Disk and/or volumes. The ARU enables user’s online recovery of lost disk members of a Disk Group, and will automatically recover Logical Disks and Volumes.
  • Array Roaming Utility
    The Array Roaming Utility gives users the ability to easily migrate drives between slots or RAID subsystems. This user friendly utility is built into the GUI of the easyRAID to simplify storage management.
  • Performance Monitoring
    A performance monitoring utility has been designed to the needs of our users. Hard disk drives, controller cache, LUNs, and host ports can be monitored concurrently with extensive detail. These statistics allow users to view current average, accumulated, maximum and minimum of the aforementioned items.
  • Event Monitoring
    Event logging has been improved with many new features and functions that are now available in the easyRAID Q16PS series. Event logs are now categorized based on their severity level and type. Entire logs are stored in non-volatile memory to prevent lost information after power has been lost or removed. Another new function is the ability to download the logs in a user readable format which can be sent to technical support for easy analysis. A system administrator can be notified of events, based on severity level, by configuring redundant email servers, or multiple SNMP servers.
  • Task Management
    With the aid of an onboard Real Time Clock (RTC) that is sync-able with an NTP server. Tasks can be scheduled to run once or periodically during off peak hours to prevent the least amount of impact on the easyRAID storage subsystem. Progress of the tasks is easily viewed from the GUI interface and can be stopped manually at anytime.
  • Selective Initialization
    There are three initialization methods supported: Regular, Background, and No Initialization; and two initialization modes: Parallel and Sequential. Regular Initialization will initialize the array, but not allow host access until the initialization process has been completed. Background Initialization will begin the initialization function, but will run in the background, allowing an array to be available for access immediately. No Initialization will bypass the initialization function, and bring an array online instantly. When initializing an array in Parallel mode, multiple arrays will be initialized together simultaneously, while in Sequential mode, arrays will be initialized in a user specified order.
  • Selective Rebuilding
    The standard rebuilding mode used is Parallel, where multiple arrays are rebuilt at the same time. However the easyRAID supports a new mode, sequential and prioritized. In sequential mode a specific array, such as a mission critical array can be given more resources to enable a quicker rebuild thus decrease time in degraded mode.
  • Regenerate Parity
    A simplified feature of Disk Scrubbing (DS), Regenerate Parity will regenerate the parity of a Logical Disk(s) in a Disk Group without a parity check.
  • PathGuard MPIO
    PathGuard MPIO software uses redundant physical paths to create a logical path to a storage subsystem to enables greater performance and reliability. PathGuard supports four different options: Read/Write I/Os, Read/Write Bytes, Command Queue, and Round Robin.
  • Read and Write Performance Optimization
    With ongoing research in performance optimization an adaptive pre-read algorithm has been developed that is able to track and recognize IO behaviors that will adjust controller cache accordingly. Pre-read depth and multipliers are adjustable to enable fine tuning for your specific application. Write cache has several options; including cache flush period, write merging, and sorting, that are also user configurable to further fine tune performance.
  • Dual Flash ROM
    Dual Flash ROM per controller gives higher RAID system availability and reliability during firmware upgrading or in the event of a single ROM failure.
  • Global or local spare disk
    With the new easyRAID Q16PS storage structure, local and global spares can be configured. Local spares will belong to specific Disk Groups and will only replace faulty drives in a specific Disk Group. Meanwhile, Global Spares will replace faulty disk in any available Disk Group.
  • 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 Clone (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.
  • Support for greater than 2TB LUN
    The easyRAID Q16P2 series natively supports 16byte CDB to allow for easy creation of LUNs greater than 2 terabytes.
  • Background Initialization
    Initialization occurs during creation of a RAID array by zeroing out / formatting drives. By default the initialization process occurs with the unit offline, and inaccessible. With background initialization, the RAID array can be accessed during the initialization process so that the unit can be setup without having to wait several hours to complete initialization.
  • BBU
    An optional BBU can be included in the RAID system to ensure data integrity in the event of a power outage. The BBU, or battery backup unit, will provide power to the on-board cache of the RAID controller in the event of a power outage. This will allow any data that is still stored on the cache to be saved until power is restored. Once power is restored, the RAID controller will flush the cache to drives.


Graphic User Interface

The easyRAID Graphic User Interface, or GUI, is a CGI-based RAID subsystem management tool which is operated using a web browser. It enables users to quickly and easily setup and configure the array, monitor status and performance, and enable event notification via SNMP and SMTP. The new GUI has many new functions and features that can greatly enhance your experience with Arena Maxtronics RAID products.
