Difference of iSCSI, NAS - 1Difference of iSCSI, NAS - 1

Network Attached Storage (NAS) usesFile-Level protocols such as NFS orSMB/CIFS for remote files sharing.

Same as traditional SCSI and FCinterface, iSCSI require Block-Levelaccess to the hard drives such asemail servers, databases, and highusage file servers.

RAID LevelSupport RAID levels 1, 3, 5, and 6 to prevent for drive failure.Sustained read performance even in degrade mode.

Disk Cloning A method to automatically copy data to spare disk and replace the sick disk. It could be configured to trigger by the following conditions:• Over bad block threshold of disk.• Detect SMART warning from disk.Disk cloning is to prevent a rebuild from ever occurring and having the unit in degraded mode.

On-line Array Roaming Array member disks has recorded specific Identification when original RAID system or controller faulty, the function provides a easily way to recognized data back by just move member disks to the same model and working RAID system.

Array Recovery A embedded utility to rescue array set back from a fatal error of when parity array (RAID 3/5/6) unexpected lose too many disks and makes array fail.

PathGuard™ MPIOA specialist software utility focusing on I/O load balancing while increasing performance by leveraging end-to-end I/O path failover and failback, and Multiple path to each device. This software is available in all Redundant series which ensuring business continuity in any event of performance is a priority.

Utility HighlightsUtility Highlights

RAIDGuard Central™ (RGC) A free centralized management software utility to provides centralized monitoring multiple RAID systems by through Ethernet at a local area network. Easier install RGC to a normal PC as an agent and then any PC/server could monitor to RAID system remotely. Allow customer to warning the engineer real-time with mail sending and most popular web messenger: MSN.


MaxSureArena unique F/W feature to support SED (Self Encrypting Drive), the drives are embedded with encryption ASIC and encryption key, to encrypt/decrypt data write / read to the drives automatically. The MaxSure are the 2 features for SED :• Instant Secure Erase • Authentication Key Management

LUN Masking LUN (Logical Unit Number) Masking is an authorization process that makes a LUN available to some hosts and unavailable to other hosts. LUN Masking is implemented primarily at the HBA level. LUN Masking implemented at this level is vulnerable to any attack that compromises the HBA.

LUN Masking support by storage is important because Windows based servers attempt to write volume labels to all available LUN's. This can render the LUN's unusable by other operation systems and can result in data loss.
