    iSCSI GbE to SAS/SATA II RAID Subsystem 3.4 iSCSI Introduction iSCSI (Internet SCSI) is a protocol which encapsulates SCSI (Small Computer System Interface) commands and data in TCP/IP packets for linking storage devices with servers over common IP infrastructures. iSCSI provides high performance SANs over standard IP networks like LAN, WAN or the Internet.
  • Page 36 iSCSI GbE to SAS/SATA II RAID Subsystem The host side needs an iSCSI initiator. The initiator is a driver which handles the SCSI traffic over iSCSI. The initiator can be software or hardware (HBA). Please refer to the certification list of iSCSI HBA(s) in Appendix A. OS native initiators or other software initiators use the standard TCP/IP stack and Ethernet hardware, while iSCSI HBA(s) use their own iSCSI and TCP/IP stacks on board.

Here are the objects, a Source VD and a Target VD. Before starting clone process, it needs to deploy the VD Clone rule first.
  • Page 108 iSCSI GbE to SAS/SATA II RAID Subsystem Snapshot space:  This setting is the ratio of source VD and snapshot space. The default ratio is 2 to 1. It means when the clone process is starting, the system will automatically use the free RG space to create a snapshot space which capacity is double the source VD.
  • Page 109 iSCSI GbE to SAS/SATA II RAID Subsystem When running out of snapshot space, the VD clone process will be stopped because there is no more available snapshot space. If this option has been checked, system will clear the snapshots of clone in order to release snapshot space automatically, and the VD clone will restart the task after an hour.
  • Page 110 iSCSI GbE to SAS/SATA II RAID Subsystem Click “Start clone”, the clone process will start. The default setting will create a snapshot space automatically which the capacity is double size of the VD space. Before starting clone, system will initiate the snapshot space.
  • Page 111 iSCSI GbE to SAS/SATA II RAID Subsystem 11. Click “Schedule clone” to set up the clone by schedule. 12. There are “Set Clone schedule” and “Clear Clone schedule” in this page. Please remember that “Threshold” and “Restart the task an hour later if failed” options in VD configuration will take effect after clone schedule has been set.
  • Page 112 iSCSI GbE to SAS/SATA II RAID Subsystem  Run out of snapshot space while VD clone While the clone is processing, the increment data of this VD is over the snapshot space. The clone will complete, but the clone snapshot will fail. Next time, when trying to start clone, it will get a warning message “This is not enough of snapshot space for the operation”.

  • Page 117: Mpio And Mc/S

    iSCSI GbE to SAS/SATA II RAID Subsystem 6.8 MPIO and MC/S These features come from iSCSi initiator. They can be setup from iSCSI initiator to establish redundant paths for sending I/O from the initiator to the target. MPIO: In Microsoft Windows server base system, Microsoft MPIO driver allows initiators to login multiple sessions to the same target and aggregate the duplicate devices into a single device.
  • Page 118 iSCSI GbE to SAS/SATA II RAID Subsystem Difference: MC/S is implemented on iSCSI level, while MPIO is implemented on the higher level. Hence, all MPIO infrastructures are shared among all SCSI transports, including Fiber Channel, SAS, etc. MPIO is the most common usage across all OS vendors. The primary difference between these two is which level the redundancy is maintained.

    iSCSI GbE to SAS/SATA II RAID Subsystem 6.11 QReplica (Optional) QReplica function will help users to replicate data easily through LAN or WAN from one subsystem to another. The procedures of QReplica are on the following: 1. Copy all data from source VD to target VD at the beginning (full copy). 2.
  • Page 125 iSCSI GbE to SAS/SATA II RAID Subsystem 2. The setting can be reverted by select “Disable QReplica” in the operation menu.  Create backup VD on the target subsystem 1. Before creating the replication job on the source subsystem, user has to create a virtual disk on the target subsystem and set the type of the VD as “Backup”.
  • Page 126 iSCSI GbE to SAS/SATA II RAID Subsystem 2. The backup VD needs to be attached to a LUN ID first before creating replication job.  Create replication job on the source subsystem 1. If the license key is activated on the subsystem correctly, a new QReplica tab will be added on the Web UI.
