CRU Q I ve hooked up the Config GUI port to my DHCP enabled network but the LCD displays an IP address that is not on my network and cannot connect to the GUI control panel using that IP address in my web browser A This may occur if you plugged in the Config GUI after RAX has already started up and initialized or if you previously configured RAX for a static network or direct connection The solution is to use the LCD interface to obtain a DHCP address Press ENT then use the A Up or V Down arrows to scroll to the option Change IP Config Press ENT The screen will say DHCP Press ENT then press the A Up arrow to select Yes Press ENT RAX will now attempt to acquire a DHCP address This new address will be displayed on the main screen of the LCD Q When try to log on to RAX using the IP address under the iSCSI configuration menu nothing happens A Sometimes when you first set up RAX you ll need to reattach the Logical Unit if it doesn t work the first time Q How many computers can connect to one data volume on the iSCSI unit A The short answer is one computer to one volume This is the safest and suggested usage of RAX If two people are accessing files on the same volume at the same time there is a very high chance that data corruption will occur There are a few file systems that can handle different users manipulating the same volume but they are not supported by Mac OS or Windows

A Avoid placing the HDD carriers close to magnetic devices high voltage devices or near a heat source This includes any place where the product will be subject to direct sunlight Do NOT allow water to make contact with the carrier or receiving frame A Before starting any type of hardware installation ensure that all power switches have been turned off and all power cords have been disconnected to prevent personal injury and damage to the hardware A To avoid overheating RAX should be operated in a well ventilated area and in such a way that sufficient airflow is maintained across the controller chips RAID A Use only hard drives that are in perfect condition Avoid using drives that have ever developed bad sectors during previous usage This could lead to possible device failure or loss of data A RAX supports SATA hard drives of various specifications and different capacities However we recommend using drives of the same brand and type for optimal performance If drives of different capacities are used in a RAID the capacity of the smallest drive will determine how much of each drive is used The additional capacity on the larger drives will not be used by the RAID A RAID level 0 will allow you to use the full combined capacity of the drives and offers the best data transfer speeds However RAID 0 offers no protection for the data If one drive fails in a RAID O the data on all of the drives is irretrievably lost Before creating a R

D sets could fail without loss of data If two drives in the same striped RAID set fail then the entire RAID will fail Two disks from each of the RAID 6 sets could fail without loss of data The loss of three disks in the same striped RAID 6 set fails then the entire RAID will fail 4 Introduction to iSCSI 4 1 What is iSCSI ISCSI is a technology that allows a data storage device to be accessed over a TCP IP network using SCSI protocols When your computer s OS receives a request for data access it generates a SCSI command and then sends an IP packet across a network or direct Ethernet connection A software utility known as an iSCSI initiator is used to generate the SCSI commands Such a utility must be installed on the computer before it can access an iSCSI storage device See Section 8 for installation instructions 4 2 What is the Benefit of iSCSI An iSCSI storage device can be placed anywhere throughout a network so the device can reside at a great distance from the computer which accesses it It is also a very fast connection when used on a gigabit network achieving speeds of 100 megabytes MB sec or more The connection it uses RJ45 standard Ethernet port is commonly found on desktop and laptop computers so there is no need to purchase potentially expensive host bus adapters to provide a connection 4 3 What is iSCSI Not iSCSI storage devices are not Network Attached Storage NAS devices They have no built in server c

However if the users connected to the volume have read only access then corruption will not be an issue Q When make more than one volume still see all volumes when connecting to the iSCSI IP address How am supposed to allow only one person per volume if that s the case A When you attach a Logical Unit to a Virtual Disk you ll probably notice a Host field with an asterisk as the default selection This means that any iSCSI Initiator will be able to connect to that volume through that Virtual Disk All iSCSI Initiators have a unique name You can use this name to restrict access to only certain computers For example if my initiator is assigned the name iqn 199105 com microsoft username01 crudataport local and if put that name into the host field when attaching a Logical Unit then only my specific computer will be able to connect to that volume You can use this to give one person read access and everyone else write access by attaching two Logical Units to one Virtual Disk Q If connect one computer to RAX and then share the files from that computer can more than one computer access the files Would the other computers need iSCSI initiators installed on them A One computer at a time can directly access RAX but files on RAX can be shared from that computer to other computers In such a scenario the computer attached to RAX acts as a server Only the server computer requires an iSCSI initiator The other computers do not need special
