There are many different kinds ofFibre connectors on varied of Fibre HBAs.13

What else you need• Hard disk drives (different RAID levels require different numbers of HDDs). Refer toSoftware Operation manual for more detail information.• Host computer with Fibre interface (Fibre-SAS RAID SYSTEM)• Host computer with SAS interface (SAS-SAS RAID SYSTEM)• Static grounding strap or electrostatic discharge (ESD) safe work area• Dedicated terminal or PC with third party communication software that supports ANSIterminal emulation (required for viewing Monitor Utility)The hard drives in a RAID system should match in size and speed. All drives inany array should be identical models with the same firmware versions. RAIDsystem can use any size drives, however the smallest drive will determine thesize of the array.There's no set formula to determine how much cache memory to use, but as ageneral rule, a workstation, with mostly very large files, such as for audio orvideo editing and playback, graphics or CAD files, can benefit from a largecache. File servers, with multiple random access of varying file size, generallyhave little or no performance improvement with additional cache.RAID system does not require the installation of different drivers for use withdifferent operating systems. RAID system is independent and transparent tothe host operating system.It is often recommended to install the hard drive with samebrand, model no., interface and capacity in this RAIDsubsystem.Due to hard drives spin at different speed and it may lead tocompatible issue or performance decline. So we do notrecommend users to install SAS and SATA hard drivemeantime in an enclosure.14

Hardware Operation ManualIt supports up to four tiers and 122 SAS/SATAII peripheral devices(SAS/SATAHDDs + Raid Enclosures) by using SAS expanders. One Volume Set supports up to 32 HDDs One SAS Raid subsystem supports up to 128 Volumes One SAS Raid subsystem supports up to 122 SAS/SATAII peripheral devices(SAS/SATA HDDs + Raid Enclosures) by using SAS expanders.There are four tiers within JBOD topology as above: First tier is a RAID System. Second tier is a SAS JBOD with a SAS CH0 on it. Connecting SAS CH0 to SASexp. Port on RAID System via a Mini SAS to Mini SAS Cable. Third tier could be two SAS JBODs with a SAS CH0 port individually. One isconnected to the SAS EXP. Port on the second tier SAS JBOD via a Mini SAS toMini SAS Cable. Another is connected to the SAS CH1/E Port on the second tierSAS JBOD. Fourth tier is a SAS JBOD with a SAS CH0 on it. Connecting SAS CH0 to SASexp. Port on third tier SAS JBOD via a Mini SAS to Mini SAS Cable.It is often recommended to install the hard drive withsame brand, model no., interface and capacity in thisRAID subsystem.Due to hard drives spin at different speed and it may lead tocompatible issue or performance decline. So we do notrecommend users to install SAS and SATA hard drivemeantime in an enclosure.58

Hardware Operation ManualRAID members need to be included at the same enclosurewhich means you need to create array in the sameenclosure. If RAID members are created from two ormore different enclosures, there would be some risks(for example: if a mini-SAS cable gets problem, moreRAID members will be lost, volume sets belong to thisArray may be failed. Shutdown RAID and JBOD to fixproblem, after that, turn on JBOD and RAID systemagain and controller will get array back, but in somecase it may not get the array back)Turniing on ffor tthe ffiirsstt ttiimeWhen cabling is completed, SAS RAID system + SAS JBOD system can be turned on.This should be done in the following order:1. First turn on the power switch of “SAS JBOD” system.2. Then turn on the power switch of “SAS RAID” system3. Power on and boot the host computer(s)Turniing offffWhen turning off SAS RAID system + SAS JBOD system, users are advised to firstshut down the server, then power off SAS RAID SYSTEM ,finally power off SASJBOD SYSTEM.59

The BBM’s backup capacityvaried with the memory chips that installed on the external RAID controller..Capacity Memory Type Battery Backup duration(Hours)1GB Memory Normal 1502GB Memory Normal 100OperationBattery conditioning is automatic. There are no manual procedures for batteryconditioning or preconditioning to be performed by the user.In order to make sure of all the capacity is available for your battery cells, allow thebattery cell to be fully charged when installed for the first time. The first time charge ofa battery cell takes about 24 hours to complete.65

Hardware Operation ManualRemoving the Battery Backup ModuleThe battery module will need to be removed for one of the following reason:Disconnect battery module if there is a long storage period before deploymentThe LI-ION battery will no longer accept a charge properly.66
