Conclusion


Storage is at the core of IP Video Management…

1.Capture & transmit Information

2.Safely store it

3.Retrieve it upon demand

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


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 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



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



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 - protectsagainst data loss during loss of power

– Disadvantages• Usually higher cost than SW or FW RAID


Storage PrimerExternal Storage Topologies

Network Attached Storage (NAS) NAS is a network appliance which can allow file sharing and storage across the LAN or WANNAS stores specific files not blocks of dataNAS resources are identified by drive letterA NAS Device IS a file server

Server Server Server Server

NAS Device

LAN



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



Fiber Channel SAN

ServerServer Server Server

FC Switch

Storage Array



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

• 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

MAID Overview

What is MAID?MAID (massive array of idle disks) Employs a select group of disk drives Only drives in active use are spinningDrives that are not active are not spinningSlow - takes several minutes to access drivesReduces power consumption


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

AutoMAIDBenefits of MAID without the limitations!

Energy savings with application performance “Green with Speed”

Supported on SAS and SATA drives

Three levels of energy savingsLevel 1, up to 20%

Level 2, up to 40% (SATA only)

Level 3, up to 60%

Fast response to 1st I/O requestsLevel 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


AutoMAIDProvides Multiple Power Level Savings

Level 1: Heads Unloaded15% to 20% savings vs. idle SATABeast w/o AutoMAID

Sub-second recovery time

Level 2: Heads Unloaded, slows to 4000 RPM35% 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
