Veritas Dynamic Multi-Pathing for VMware improves storage I/O performance and availability for VMware environments. It provides load balancing across storage paths and controllers, proactive path management to avoid disruptions, and visibility into storage characteristics. The solution offers increased performance through adaptive load balancing policies and improved availability with automated path recovery. It also bridges communication between storage and server teams by providing centralized management and detailed I/O statistics and metrics in vCenter.

2. Virtualization puts increased pressure on storage
performance and availability
Performance & Resiliency Storage Heterogeneity Visibility & Reporting
RAID10, SRDF, Thin , SSD drive
• SAN aware load balancing • Flexibility to choose ANY • Visibility into storage
key for high VM density cost effective storage characteristics needed
• Proactive failover of storage • Optimized handling of ANY • Data center wide I/O
connectivity during disaster tier of storage bottlenecks critical to isolate
I/O bottlenecks to storage arrays! Getting locked-in by single array vendor
Lack visibility into performance bottlenecks!
Device naming complicated in ESX! Am I using the right tier of Storage?

4. Optimize I/O throughput for greater performance
• Choose between seven I/O policies
to achieve greatest performance
for particular workload or storage
array (for example):
– MinimumQueue (MinQ) I/O Policy
– Adaptive I/O Policy
– Adaptive-MinQ
– Balanced
– Round-Robin, Single-Active, Priority
• Multi-threaded for faster discovery
and recovery
• Load balancing of paths across
controllers

servers, what tier of storage is
it using? SSD, SATA, SAS, FC? • from vendor list
App Team
• is replicated
• where raid level is 5
• where LUN type is
My mission critical file system
is being protected or not? • where Media type is
RAID5, RAID10?
