This information is confidential and is not to be provided to any third party without Vicon Industries Inc.’s prior written consent. Common RAID Storage Definitions  Storage Recovery, Not Backup  Mirroring: Data redundancy  RAID: Redundant Array of Independent Disks  Striping: Spreading data across two or more disks.  Parity: Error Detection

This information is confidential and is not to be provided to any third party without Vicon Industries Inc.’s prior written consent. Most Common RAID  RAID 0, 1 and 10 are also available  RAID 5 is the most popular –Advantages: Cost efficient Fault Tolerance Perfect for video storage Most activity is read activity  RAID 6: Similar to RAID 5 –Parity information is written twice Greater fault Tolerance Slower performance

Storage Primer RAID Controllers  Software RAID –OS based disk controller –Advantages Low cost – no hardware requires Cost effective alternative for small server environments –Disadvantages Dependant upon OS for all storage functions Shares CPU processing cycles w/OS and other apps Proprietary to specific OS Not scalable to enterprise class data centers

This information is confidential and is not to be provided to any third party without Vicon Industries Inc.’s prior written consent. Storage Primer RAID Controllers  Firmware RAID –Driver based disk controller Uses generic HDD controller with firmware driver set Sometimes known as “HostRAID” or “fake RAID” –Advantages Off-loads some processing to HW ASIC Less costly than HW RAID –Disadvantages Limited drive selection - Specific to controller Still requires server CPU to do most RAID processing

This information is confidential and is not to be provided to any third party without Vicon Industries Inc.’s prior written consent. Storage Primer RAID Controllers  Hardware RAID - the Gold standard –Advantages High Performance Requires no server/CPU resources Supports multiple HDD formats Can support many operating systems Can support multiple HDD formats Usually supports non-volatle cache - protects against data loss during loss of power –Disadvantages Usually higher cost than SW or FW RAID

This information is confidential and is not to be provided to any third party without Vicon Industries Inc.’s prior written consent. Storage Primer External Storage Topologies Network Attached Storage (NAS) NAS is a network appliance which can allow file sharing and storage across the LAN or WAN NAS stores specific files not blocks of data NAS resources are identified by drive letter A NAS Device IS a file server Server NAS Device LAN

This information is confidential and is not to be provided to any third party without Vicon Industries Inc.’s prior written consent. Storage Primer External Storage Topologies  Network Attached Storage (NAS) –Advantages Most cost effective external storage topology Uses existing LAN for connectivity Can use low cost COTS HW –Disadvantages Dependant upon LAN for all storage file transfers. Must run OS based file protocol (NFS…) Not usually enterprise class for availability Not highly scalable Possible CPU choke point in Not usually good fit for mass data transfer – like DVS
