Virtualization Trends & Challenges 1

Storage I/O Performance & Resiliency with DMP 2

Business Critical High Availability with VCS 3

Q&A 4


Virtualization puts increased pressure on storage performance and availability


• SAN aware load balancing key for high VM density

• Proactive failover of storage connectivity during disaster

• Flexibility to choose ANY cost effective storage

• Optimized handling of ANY tier of storage

• Visibility into storage characteristics needed

• Data center wide I/O bottlenecks critical to isolate

Performance & Resiliency Storage Heterogeneity Visibility & Reporting

RAID10, SRDF, Thin , SSD drive

I/O bottlenecks to storage arrays!

Lack visibility into performance bottlenecks!

Getting locked-in by single array vendor

Am I using the right tier of Storage? Device naming complicated in ESX!


Virtualization brings challenges visibility and availability of applications


• Application view and health status through vSphere

• OS and Application recovery

• Reduce planned and unplanned downtime

• Reduce outage during OS & application patching

• Application relationship management

• Physical and virtual environment

Application Control & Visibility

Challenges

• Native storage device names overly complex

• Native naming lack detailed array vendor or LUN information

LSN sorting algorithm

• Consistent names across servers

• Intermediate for arrays that lack AVID naming

Array Volume ID (AVID) naming

• Exposes LUN details to server admins

• Meaningful names for storage teams

Enables AVID naming to make names meaningful for server and storage teams

• from vendor list

• is replicated

• where raid level is 5

• where LUN type is

• where Media type is

Is my critical data being replicated underneath or not?

Is mission critical file system is being protected or not? RAID5, RAID10?

My application is on tier 1 servers, what tier of storage is it using? SSD, SATA, SAS, FC?

Centralize operations by managing in vCenter


Enables active management and

infrastructure insight Plugin provides Dynamic Multi-Pathing storage and

performance visibility


Respond quickly with active path management


• Perform active path and policy management inside vCenter

• Change load-balancing algorithm on the fly

• Enable / disable individual path components


Operational visibility of storage performance and I/O statistics


• Visibility at infrastructure component level

• Granular performance metrics

• Tabular or graphical I/O Statistics


Deeper visibility into storage enabling better decisions


• Deep visibility of the storage for your VMware environment

• Globally rename arrays, enable/disable array ports across hosts

• Easily identify storage load by array, port, host or LUN

• Correlate I/O load from individual virtual machines and disks


Unique vSphere Web Client visibility


• Visual host to storage connectivity mapping

• Filter connectivity map on criteria such as array, VM Guest, etc.

• Management parity with vSphere Client or vSphere Web Client


Dynamic Multi-Pathing Command Line Interface


Uncompromised visibility into VMware’s storage infrastructure

• Enable / disable paths

• Select I/O balancing policies, on the fly

• Display DMP configuration (ASL/APM, tunables)

• Granular I/O statistics (enclosure, path, LUN, port)


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):

– Minimum Queue (MinQ) I/O Policy

– Adaptive I/O Policy

– Adaptive-MinQ

– Balanced

– Round-Robin, Single-Active, Priority

• All available LUN paths used by default

– Eliminates manual path configuration

– When the application SG is switched from VM1 to VM2

• The offline routine of VMwareDisks detaches the disks from VM1

• The online routine on the failover target node then attaches the disks to VM2.

– VCS infrastructure detects faulted node and initiates a SG failover

– SG begins to online on failover target node

– VMwareDisks agent online routine detects that the disks are not detached from the faulted node

– The agent fires Detach Disks operation to the ESXi host of faulted VM.

– Once detach completes, the agent proceeds to attach the disks on the failover target node

– VMwareDisks online routine is vSphereHA aware and it waits till the faulted VM is migrated completely

– Then VMwareDisks agent fires detach disk operation from faulted VM on the new ESXi host

– The agent proceeds with online (attach disks) operation on the failover target node

– SG failover complete

– ESX crash – SG begins to online on failover target node

– Since vSphereHA is disabled, the VM stays on the faulted ESXi host

– VMwareDisks agent’s online routine (on failover target) then registers the faulted VM on its ESXi host

– Once registration completes, VMwareDisks agent detachs disk operations from faulted VM on the ESXi host

– Proceeds with online (attach disks) operation on the failover target node

– SG failover complete


Operational Scenarios Handling Split brain scenarios

ESXi 2

– Network split:

• In scenarios of network split, the passive node would detect active node down and initiate a SG failover.

• Detach operations wont succeed implying the locks are not released, the attach operations too fail. This causes the failover to error out “status quo” is maintained, avoiding data corruption.

• Applications are the real business value

– Maintaining availability of applications is highest priority

– Reliance on point solutions for various platforms increases complexity

– Orchestration of business services provides holistic management

• Minimize impact when business needs change

– Moving P2V or V2P shouldn’t require complete re-design for availability

– Be prepared for new technologies
