VDI Storage Challenges

Storage Sizing and Design for VDI is complex

• Performance requirements make it hard to get the right design

• Traditional storage architectures impose certain limitations

• 10x difference between average and peak I/O needs

• Highly correlated “storm” events (boot, log-in, AV scan)

• Wrong design results in dissatisfaction, drives up cost

Costs

• Very Expensive – Storage is the main driver of VDI acquisition costs

• Designing for peak I/O needs is cost prohibitive

How to Enable Event Syslog

Configured using vdmadmin (disabled by default)

• vdmadmin -I -eventSyslog -disable

• vdmadmin -I -eventSyslog -enable –localOnly

• vdmadmin -I -eventSyslog -enable -path path -user mydomain\myuser -

password mypassword

Settings from any Connection Server in a “cluster” affect all

50

USB Enhancement Details

Interoperate with other VMware products

Claim in-use devices - this affects a large number of devices and

causes aggravation for a lot of customers

Devices that reset themselves are automatically re-forwarded.

Notably Blackbery / iPhone system update, SanDisk Cruzer

The driver for a device does not need to be installed on the client

machine

Complete implementation of Windows USB interfaces

Kernel event tracing

New Device Filtering mechanism (Client & Agent on Windows):

• Better support of splitting of functionalities of composite devices. Easier for

users to define custom settings for specific devices

• Usage of admin templates to drive/set the settings – improving usability

Digests can only be configured (created) if the VM is powered off

View Storage Accelerator – Cluster/Host Setting

58

Anatomy of a VDI Workload

VDI workloads are driven by Windows Guest operations

• Windows OS optimized for spinning disk media

• Random 4K block operations – 30%Read – 70%Write

• Windows OS breaks down a single IOP into multiple IOPS

Highly concurrent workloads

• Multiple Desktops performing similar operations – Ex: Browsing Internet,

Application specific operations – Open, close, read, write, save

High variance workloads

• Peaks of activity followed by steady state

• Peaks influenced by event risk – Boot Storm, AV Storm, Login Storm, IO bursts etc

59

View Storage Accelerator – How Does It Work?

Three phases required to fully operationalize the use of cache

Setup Phase – User driven

• Enable use of VSA on a per pool basis – User selects disk type (OS/OS+user)

• Configure Cache size – 100MB & 2GB (Default 1GB)

• Setup generates a digest for each vmdk

Operational Phase – Automatic if VSA configured

• Common blocks are cached in ESX Memory – Cache warms up as common

blocks are read

• Reads of common blocks by Desktop VMs served from memory

• Writes to common blocks invalidates cache for that block

Regenerate Phase – Policy Driven

• Regenerate required when a large portion of the cache contains invalid blocks

• Recomputes digest and enables cache warm up

Problem Statement

Space Efficient Virtual Disks – Solution to Clone Growth

OS Disk/Redo Log Grows in size over time

Efficient Disk Space Management – Allocated space always in use

Capacity optimized new disk format for use by View Composer Linked Clones

Guaranteed 4K grain size

Unused space reclamation

View Linked Clones (Redo Log portion of disk) grow in size with progression of time

• Size of redo log almost equivalent to the size of the base image over a few months

With the current vmdk disk format, unused allocated space cannot be reclaimed
