  2. Storage Solutions 2010 Agenda • Storage – Role in IP Video • Storage primer • HDD technology • RAID levels & descriptions • Storage topologies • VICON Nexsan product overview • SataBoy • SataBeast • Other Products • Conclusion

  3. Storage – Role in IP Video • Storage is at the core of IP Video Management… • Capture & transmit Information • Safely store it • Retrieve it upon demand

  4. Storage Primer

  5. Storage Primer • HDD & Buss Technologies IDE/ATA SATA – Serial ATA • SCSI- Small Computer • System Interface Fibre channel SAS - Serial Attached SCSI SATA Connector SCSI Connector

  6. 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

  7. 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

  8. Storage Primer • RAID 5, Block striping w/distributed parity P Parity Generator Server A0 B0 D0 P3 PARITY C0 P3 PARITY A1 B1 C1 E1 A2 B3 D2 E2 P3 PARITY P3 PARITY A3 C3 D3 E3 B4 C4 E4 P4 PARITY D4 A Blocks B Blocks C Blocks D Blocks E Blocks

  9. Storage Primer Striped set with dual distributed parity • RAID 6 – Block striping, dual parity P Q XOR Parity Generator (P) ECC code Generator (Q) Server P2 PARITY A0 B0 Q0 PARITY C0 P1 PARITY A1 B1 Q1 PARITY E1 P2 PARITY A2 Q2 PARITY D2 E2 P3 PARITY Q3 PARITY C3 D3 E3 P4 PARITY B4 C4 Q4 PARITY D4 A Blocks B Blocks C Blocks D Blocks E Blocks

  10. Storage PrimerRAID 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

  11. Storage PrimerRAID 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

  12. Storage PrimerRAID 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

  13. Storage PrimerExternal 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 Server Server Server LAN NAS Device

  14. Storage PrimerExternal 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

  15. Storage PrimerExternal Storage Topologies • Fiber Channel SAN LAN Server Server Server Server FC Switch Storage Array

  16. Storage PrimerExternal Storage Topologies • Fiber Channel SAN • Advantages • Very fast block level data transfer • Requires no server/CPU resources • OS agnostic • Highly fault tolerant • Highly scalable • Disadvantages • Higher cost than NAS or DAS • Distance limitations

  17. Storage PrimerExternal Storage Topologies • iSCSI SAN LAN Server Server Server Server iSCSI over Ethernet GB Ethernet Switch Storage Array

  18. Storage PrimerExternal Storage Buss • iSCSI SAN • Advantages • Requires no server/CPU resources • Uses standard Ethernet componentry • GB Ethernet & NIC devices • More cost effective than FC in many applications • Highly scalable • Disadvantages • Still subject to certain Ethernet overhead • Not as high throughput or redundancy as FC Fabric

  19. Storage PrimerExternal Storage Topologies - iSCSI SAN

Boy and Beast Product Family Simple to Learn and Manage NexsanNexScan onboard intuitive web/browser based GUI Nexsan Tele-Guard provides standard SNMP and phone home alerts NexsanWorldView delivers active centralized monitoring of all Nexsan systems Use Nexsan WorldView to simultaneously manage several Nexsan SAS/SATA storage systems

  30. Nexsan is Very Simple to Learn and Manage

  31. MAID Overview • What is MAID? • MAID (massive array of idle disks) • Employs a select group of disk drives • Only drives in active use are spinning • Drives that are not active are not spinning • Slow - takes several minutes to access drives • Reduces power consumption

  32. Why is Nexsan AutoMAID Better Old MAID Reduces application performance for energy savings “On-or-off” approach to energy savings Usually only supported on SATA drives Minutes to spin up components to respond to IO requests Slow response confines use to just a few applications AutoMAID Benefits of MAID without the limitations! • Energy savings with application performance “Green with Speed” • Supported on SAS and SATA drives • Three levels of energy savings • Level 1, up to 20% • Level 2, up to 40% (SATA only) • Level 3, up to 60% • Fast response to 1st I/O requests • Level 1, sub-second • Level 2, less than 15 seconds • Level 3, less than 30 seconds • Fast and flexible response broadens use to include a wide range of applications Save up to 60% in energy costs

  33. AutoMAIDProvides Multiple Power Level Savings • Level 1: Heads Unloaded • 15% to 20% savings vs. idle SATABeast w/o AutoMAID • Sub-second recovery time • Level 2: Heads Unloaded, slows to 4000 RPM • 35% to 45% savings • 15 second recovery time • Level 3: Stops spinning (sleep mode; powered on) • 60% to 75% savings • 30 to 45 second recoverytime 42TB uses 620 watts when idle; drops to less than 250 watts in Level 3 AutoMAID

  34. AutoMAIDAnnual Energy Cost Savings Energy Costs in $1,000s Energy Costs in $1,000s Source – StorageIO Group – Solutions Brief – MAID 2.0 2008 – reflects 1.3PB of On-line Storage Nexsan Boy and Beast Gen Prod Family Pres GA051608-A
