ArrayMasStor K Series Identifying rear panel components Several of the RAID systemÕs components are accessed from the rear of the unit. See figure 8 below for locations and brief descriptions of these components. Status indicators (LEDs). The POWER indicator is lit when power is applied to the unit. BUSY is lit when the system is powering up and when the unit is processing data and is unable to respond to new requests. -
Page 12: Product Components
ArrayMasStor K Series Product Components The K-Series RAID system consists of a RAID controller (SCSI-to-IDE); six IDE drive bays and drive tray assemblies; redundant, hot-swappable power supplies; redundant, hot-swappable fans; and an enclosure to house and integrate these components. RAID Controller The SCSI-to-IDE controller used in the K-Series RAID system is the central element of the product. -
Page 13: Raid Overview
ArrayMasStor K Series RAID Overview Redundant Array of Inexpensive Disks (RAID) is a storage technology used to improve the performance, and increase the reliability, of a data storage system. This technology was developed around the idea of grouping multiple disk drives together (an array) to provide features and functionality thatÕs not available in a single disk drive. -
Page 14: About Raid Levels
ArrayMasStor K Series Since the K-Series RAID system does not support non-RAID storage configurations, a minimum of two disk drives must be installed into the unit. The following section describes each of the RAID levels supported by the system. About RAID levels RAID generally has six common levels (or defined configurations): RAID 0 ~ 5. -
Page 15: Raid 1 (0+1)
ArrayMasStor K Series NOTE: One drawback to RAID 1 is that it does not usually allow run-time expansion. Once a RAID 1 array has been created, to expand it, the data must be backed up elsewhere before new drive(s) can be added. Other RAID levels generally permit run-time expansion. -
Page 16: Spare Drives In Raid Configurations
ArrayMasStor K Series RAID 5 offers increased data transfer rates when data is accessed in large chunks (i.e., sequentially) and reduced data access time for many simultaneous I/OÕs when they do not span more than one drive. Spare drives in RAID configurations RAID implementations include one other basic concept that can be introduced at this point: spare drives. -

Page 19: Removing A Power Supply From The Raid System (With Power Off)
ArrayMasStor K Series Removing a Power Supply from the RAID system (with power off) WARNING Ð The RAID system must be powered OFF before performing the following procedure. Redundant Power Supplies The K-Series RAID system has two independent, redundant power supplies. Each power supply receives current from the same power cable, and each supply is capable of providing all necessary power to the array and enclosure. - Page 20 ArrayMasStor K Series To reinsert a power supply into the system, carefully slide the power supply into the unit until the locking latch ÒsnapsÓ the power supply into position. The power supply fits snuggly and can require a firm push, at the end of its travel, to engage the securing latch.

Page 28: Troubleshooting
ArrayMasStor K Series Troubleshooting Controller Problems with the controller fall into two categories, serious and disastrous. The controller is the only major component in the K-Series RAID system that can cause a fatal failure on its own. After the system ÒPower On Self TestÓ (POST) is complete, the controller will begin initializing the RAID. -
Page 29: Fans
ArrayMasStor K Series will light. On the power supply itself, the status LED(s) will change from Green to Amber (or extinguish completely), indicating which power supply has failed. Because the unit comes with redundant power supplies, it is possible to replace a failed power supply without powering down or otherwise interrupting data flow. -
Page 30: Drive Trays
ArrayMasStor K Series Drive Trays Drive trays as a component separate from drives are unlikely to encounter problems unrelated to a drive failure. In the event that you suspect a drive failure may in fact be a problem with a drive tray, shut down the host, remove the questionable drive and tray, and examine the power and data cables to see if they have come loose or are damaged. -
Page 31: No Spare Installed
ArrayMasStor K Series NOTE: It is highly recommended that you replace a failed drive even if you already have a spare. An installed spare provides an additional safeguard against future drive failures. No Spare Installed If there is no hot-ready spare drive installed, a single drive failure in a RAID1, RAID3, or RAID5 array will still not result in data loss or downtime. - Page 32 ArrayMasStor K Series The K-Series RAID system can only have one host connected at a Single Host Limitation time. Sharing the array storage capacity is accomplished through the (Important) host OS and hardware, not through the K-Series RAID system. Auto RAID Setup via It is recommend that Auto RAID Setup be used via the LCD display panel to create an array.
