SAN 101 : Host layer
24
Host layer of SAN is made up of server and its components like
• Host bus adapter (HBA)• Host bus adapter drivers• Gigabit Interface Converter (GBIC)• Cables
SAN 101 : Fabric layer
25
Fabric layer is the actual, tangible network part of the SAN. Which moves data around from a source to a destination.
• SAN Hubs• SAN Switches• Data routers• Protocol bridges• Gateway devices• Cables

26
Storage layer consists of all the disk and tape arrays that stores your data
Some of the Key Players in Storage Industry
27
NetApp
28
Lets see what makes
stand out!!
NetApp : Philosophy
29
NetApp believes in one tool for many jobs
Data ONTAP®
NetApp : Data ONTAP
Based on FreeBSD Unix like operating system
Implements proprietary file-system called WAFL (Write Anywhere File Layout)
Implements proprietary redundancy algorithm NetApp® RAID-DP®
30
Data ONTAP : Features
Data Deduplication & Compression
FilerView Tool
NetApp Flash Pool
NetApp FlexShare
NetApp FlexVol
RAID-DP
NetApp Snapshot
31
NetApp : Protection Software MetroCluster
SnapVault
SnapRestore
SnapLock Compliance and SnapLock Enterprise Software
SnapMirror Data Replication
SnapProtect Management Software
32
33
Let’s have a look at how each of these protection
software work!
NetApp : WAFL
It is implemented similar to log-structured file system
Snapshots is one of the most salient feature of WAFL. It is a read only copy of the file system. This gives raise to a host of software products from NetApp
Supports Unix like file & directory layout for NFS users and Microsoft file & directory layout of CIFS users i.e. Windows and Unix users can use the same networked volumes
34
MyAutoSupport : Icing on the cake
Is a suite of web-based applications hosted on the NetApp support site which helps you Analyse, Model and Optimize your storage
NetApp AutoSupport has to be enabled by the customer/vendor to leverage all the tools in NetApp My AutoSupport
My AutoSupport proactively identifies storage infrastructure issues through a continuous health-check feature and automatically provide a step-by-step plan to avoid disruptions
