1. Storage Basic Components
Storage Box:
• Controller/Head.
• Disk Shelf.
• Disk Bay.
• Disk.
• SAN Switch.

2. Server requirement for Storage
FCP SAN
• HBA – Host bus adapter (Initiator)
• MPIO – Microsoft Multipath I/O
iSCSI SAN
• iSCSI initiator Software

3. Different Vendor In Storage

4. NetApp vs other Storage boxes
• NetApp – Operating System is used to
administrator (DataOntap).
• DataOntap – Is based on BSD Unix and its
filesystem is WAFL.
• Consistency point.
• EMC,SUN,Hitiachi – Uses embedded operating
system, firmware.

5. Infrastructure for SAN

6. Storage Technology
SAN
• Block-Level Access
• Protocols – FCP, iSCSI
NAS
• File-Level Access
• Protocols – nfs , cifs

7. NetApp Hardware Architecture

8. Accessing the Filer
• Command Line Interface – CLI
• Filer view – Web access GUI
• System Manager – GUI

9. Aggregate
• It is collection of RAID Group
• NetApp DataOntap supports RAID4 & RAIDDP

10. Volume
• Volumes contain file systems that hold user
data that is accessible using one or more of
the access protocols supported by Data
ONTAP, including NFS, CIFS, HTTP, FTP, FC, and
iSCSI.
There two types of volumes in NetApp.
• Traditional Volume
• Flexible Volume

11. LUN
The LUN Multiprotocol Type, or operating
system type, specifies the OS of the host
accessing the LUN.
• LUN can be accessed with full path only
• A LUN must have a unique identification
number (ID) so that the host can identify and
access the LUN
