๏ RAID - Redundant Array of Independent (or Inexpensive) Disks ๏ Combines multiple disk drives into a logical unit to provide faster data transfer speed and/or higher reliability, depends on the RAID level ๏ Most higher-end hardware RAID controller can support standard RAID levels such as RAID 0, 1, 5..., as well as nested RAID levels such as RAID 0+1, etc ๏ RAID - Redundant Array of Independent (or Inexpensive) Disks ๏ Combines multiple disk drives into a logical unit to provide faster data transfer speed and/or higher reliability, depends on the RAID level ๏ Most higher-end hardware RAID controller can support standard RAID levels such as RAID 0, 1, 5..., as well as nested RAID levels such as RAID 0+1, etc Concept What is RAID?

๏ Able to combine multiple disks into one big disk so that no disk space will be wasted ๏ Able to create one or more redundant copies from a single source disk to prevent data loss caused by hardware failure ๏ Able to gain much higher read/write speed for applications which requires large amount of data transfer and access needs ๏ Able to combine multiple disks into one big disk so that no disk space will be wasted ๏ Able to create one or more redundant copies from a single source disk to prevent data loss caused by hardware failure ๏ Able to gain much higher read/write speed for applications which requires large amount of data transfer and access needs Concept Why RAID?

๏ NAS - Network Attached Storage NAS storage provides both storage and file system, to the client computer, a NAS storage often appears as a “share folder”. ๏ SAN - Storage Area Network SAN storage provides storage only, and the file system is handled by the operating system, a SAN storage appears to be “locally attached” to the client computer, which can be partitioned and formatted to a desire file system. ๏ NAS - Network Attached Storage NAS storage provides both storage and file system, to the client computer, a NAS storage often appears as a “share folder”. ๏ SAN - Storage Area Network SAN storage provides storage only, and the file system is handled by the operating system, a SAN storage appears to be “locally attached” to the client computer, which can be partitioned and formatted to a desire file system. Concept What is NAS & SAN?

๏ NAS - Network Attached Storage NAS is often slower than SAN due to multi-protocol (multiple translations), but can be accessed by multiple clients at the same time. ๏ SAN - Storage Area Network SAN is like a external hard drive but connects through a network connection. Due to this reason, a SAN shouldn’t be accessed by multiple computers at the same time (unless accessed using read-only permission). ๏ NAS - Network Attached Storage NAS is often slower than SAN due to multi-protocol (multiple translations), but can be accessed by multiple clients at the same time. ๏ SAN - Storage Area Network SAN is like a external hard drive but connects through a network connection.

GV-Storage System The LCM module is the core of the GV-Storage System GV-Storage System is a standard *iSCSI storage iSCSI is SCSI protocol over TCP/IP

GV-Storage System LCM can be used for RAID creation and showing system status

GV-Storage System Ethernet Port for Web UI Two Ethernet Ports for Dual- channel Data Transfer Two Ethernet Ports for Dual- channel Data Transfer

GV-Storage System Redundant Power Supply Unit

GV-Storage System Network & RAID configuration can be done using the web UI

GV-Storage System Creating a Logical Unit ๏ Group multiple “physical disks” together as a “Volume Group” ๏ Slice the volume group up into “User Data Volume” ๏ Assign a user data volume as a “Logical Unit” which can then be connected by the client (using an iSCSI initiator) ๏ Group multiple “physical disks” together as a “Volume Group” ๏ Slice the volume group up into “User Data Volume” ๏ Assign a user data volume as a “Logical Unit” which can then be connected by the client (using an iSCSI initiator)

GV-Storage System iSCSI Initiator acts like a SCSI interface card which makes the OS understand the SCSI command sent through the TCP/IP

GV-Storage System Once an iSCSI target is connected, it appears as an unformatted hard drive

Backup Server What is Backup Server? ๏ Backup Server provides near realtime data redundancy protection to existing DVR/NVR ๏ Backup Server is able to do backup manually, near realtime, or by a pre-configured schedule ๏ Backup Server can backup video/audio log to any local or remote storage as long as the storage can be assigned with a drive letter (e.g. D:\, E:\...etc) ๏ Backup Server also backs up system log.MDB file everyday ๏ Backup Server provides near realtime data redundancy protection to existing DVR/NVR ๏ Backup Server is able to do backup manually, near realtime, or by a pre-configured schedule ๏ Backup Server can backup video/audio log to any local or remote storage as long as the storage can be assigned with a drive letter (e.g. D:\, E:\...etc) ๏ Backup Server also backs up system log.MDB file everyday

Backup Server D: E: F: GV-Storage System 3rd Party SAN 3rd Party SAN 3rd Party NAS 3rd Party NAS Local Storage

Backup Server Backup can be done by selecting files manually, near realtime (“Any Time” option) or by schedule

Backup Server Playback can be done: ๏ by using GeoVision Backup Viewer if an iSCSI storage is used ๏ by mounting the remote storage as a network drive, then playback the video using ViewLog or Remote ViewLog ๏ by using GeoVision Backup Viewer if an iSCSI storage is used ๏ by mounting the remote storage as a network drive, then playback the video using ViewLog or Remote ViewLog

Backup Server GeoVision Backup Viewer can also be used to review the System Log

Backup Server Make sure the local or network storage is properly mounted Use the “Browse” option in the ViewLog to load all video/audio data

Hot Swap HDD Tool Hot Swap HDD Tool (MediaManTools) allows storage to be add or removed during runtime
