What is iSCSI?
iSCSI is an abbreviation of Internet Small Computer System
Interface (SCSI) an IP-based storage networking standard for linking
data 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 Storage
(iSCSI vs SCSI)
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.

Storage Attached Network
(iSCSI vs FC)
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, NAS
Same as traditional SCSI and FC
interface, iSCSI require block-level
access to the hard drives such as
email 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.

Redundant System Overview
 Maxtronic redundant system design extends the nosingle-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
Cache Coherence Channels
- Object state
- Write cache
Controller A
Controller B
 The write-cache data is preserved only when one of
the controller is failed.
