What is iSCSI?What is iSCSI?

iSCSI is an abbreviation of Internet Small Computer SystemInterface (SCSI) an IP-based storage networking standard

for linkingdata storage facilities by DAS or SAN connections.

Unlike traditional SCSI and Fibre Channel, which requires special

purpose cabling, iSCSI can be run over long distances using existing

network infrastructure.By carrying SCSI commands over IP networks.


Direct Attached StorageDirect Attached Storage (iSCSI vs SCSI) (iSCSI vs SCSI)

SCSI CableSCSI Cable~12m~12m

Network CableNetwork Cable~100m~100m

SCSISCSI iSCSIiSCSI

iSCSI requires normal Ethernet cable to directly connect server and RAID; unlike SCSI must use specific SCSI HBA and cable.

Directly connection length of iSCSI cable reaches to 100 meter which much over maximum 12meter of SCSI cable.


FC SANFC SAN

FC Switch

iSCSI SANiSCSI SAN

FC SANs are dedicated storage networks, whose deployment requires specialized host bus adapters, specialized FC switches and FC storage arrays. Although all of these components are costly and add a layer of complexity

iSCSI can easily be deployed on the commodity networking hardware without expansive equipments of FC HBA, cable and switch.

Difference of iSCSI, NASDifference of iSCSI, NAS

Same as traditional SCSI and FCinterface, iSCSI require block-levelaccess to the hard drives such asemail servers, databases, and high usage file servers.

Network Attached Storage (NAS) uses

file-based protocols such as NFS or

SMB/CIFS for remote files sharing.

Maxtronic redundant system design extends the no-single-point-failure to the controller entity.

Two controllers in one system. They are named by controller A (left/top), and controller B (right/bottom).

A full-duplex RCC (redundant communication channel) is established for synchronization purpose.

- Configuration

- Object state

- Write cache

The write-cache data is preserved only when one of the controller is failed.
