5. What Are the Challenges in
Today’s Storage Environment?

6. Challenges
• Storage landscape is rapidly changing and new storage models are emerging resulting in
increased MTTI & SLA
– Converged Infrastructure
– Flash Based Arrays
– Software Only Storage
– Cloud Based Storage
• Heterogeneous Environment
– File and Block Storage Arrays – NFS, iSCSI, FC, FCoE
– Scale Out Storage - VSAN
– Switches – FC, FCoE, Ethernet, SAS
• Cost - Storage is expensive - Excess Capacity (Same thing that happened in compute
virtualization – from allocation based to demand based)
• Lack of Skillset as technology is evolving so quickly and where to draw line what belongs to
storage team and what belongs to compute team
CONFIDENTIAL 7

7. Challenges - Continued
• Data Services – Snapshot, Replication etc.
• VM Mobility
– vMotion, Storage vMotion
• Scale
– Hundreds - Thousands of Servers
– Thousands – Millions of VM
– 1Gig, 16Gig – 40Gig Throughput
CONFIDENTIAL 8

8. Why vR Ops for
Troubleshooting Storage?

9. Complexity in Storage Operations
Lacking end-to-end visibility into storage stack
• Need visibility from the VM > Fabric > Array for proper root-cause
analysis
1
No VM > Array
mapping
Current frameworks provide limited visibility
• SMI-S implementations vary across vendors and provide
inconsistent information
2
Lacking a holistic
approach
Lack of correlation between Compute, Storage &
Network issues

Delays

IOStatsProfile is an optional spec in VASA 2.0 (based on SMI-S specifications)
and brings stats support for the storage objects in the VASA spec such as:
1. Storage Array
2. Storage Processor
3. Storage Port
4. Storage LUN
5. File System
6. Virtual Volume
Mandatory
• TotalIOs
• KBytesTransfered
• IOTimeCounter
• ReadIOs
• ReadIOTimeCounter
