6. Instant Volume Creation
Create and use a volume in seconds
Give it a volume name
Select the storage tier
Determine the size
That’s it – you’re done
Like RAID types are pooled into a single storage tiers
The volume is automatically created from the selected pool
iSeries load balancing assigns the volume to the least used iSeries host port
Volume is automatically exposed to the iSCSI SAN network
Volume is ready to be used by the server
Nexsan iSeries™ General Product PPT GA A

7. New iSeries Feature - QoS – bandwidth management for iSeries tiered storage environments
Ensure bandwidth for demanding high performance applications
Applications using SAS storage can be given priority over applications using SATA storage to ensure optimum performance and responsiveness.
The user can configure iSeries bandwidth and control how much bandwidth is given to SAS based applications as opposed to SATA based applications
If SAS is not being accessed – bandwidth is given 100% to SATA until SAS bandwidth is required

VMware
Hyper-V
OLTP
Print servers

Example shows SATA bandwidth limited to 50MBs
Applications using SAS will have full use of the remaining bandwidth (approx. 220 MBs)

8. Nexsan iSeries™ Automated Storage Services
Windows SQL and Exchange Setup Wizards
Meets Microsoft best practices requirements
Automatically creates separate volumes for LOGs and DATA
Automatically configures iSeries bandwidth mangers
Automatic storage pooling
All storage resources with the same drive and RAID type can be placed into a single “POOL”
When volumes are created, iSeries will automatically select the best resource within the pool to deliver optimal performance
