Addressing Patch Pain Points
Current Pain
6
VMware Solution
Patching success and coverage is
uncertain or poor
Leverage VC awareness and ability
to deal with offline and suspended
guests
Systems need to be backed up before
patching
Automatic backup and rollback
capability
Patch deployment requires either target
OS agent or proper authentication
criteria
All VMs are known to VC and
VMware Tools provides a constant
agent on guest VM
Frequency of patch deployment
Reduced downtime can decrease the
impact of frequent patch deployment
Patch needs to be tested at OS and
application level
Automated testing for OS and
leverage customer’s current QA tools
for application testing
Differing approaches to VM and ESX
patching
Unified patching framework

VMware Confidential
Compliance
What is compliance?
When a VM or host contains all updates in a baseline
How is compliance checked?
By evaluating results of security scan through the security tab for
VMs or hosts
Current compliance status is only as fresh as the most recent
security scan!
10
VMware Confidential
Understanding Security Scans
What is a security scan?
A process initiated from the VI client to check VM and host
compliance
Can scan a host, VM, resource pool, cluster, folder or data center
What does a security scan do?
Compare each object (VM or host) against a specified baseline
Reports back through a single event the objects that do not match the
baseline
When are scans performed?
When initiated by the user
At scheduled intervals through “Scheduled Tasks”
11
VMware Confidential
Compliance Status
Available through “Update Manager” tab for VMs and hosts
Three statuses for compliance
Compliant: VM contains all updates in baseline
Not compliant: VM lacks one or more updates
Unknown: VM not yet scanned
Note that only VMs that the user has permission to see are displayed!
12
VMware Confidential
Remediation
What is remediation?
The process of bringing a VM or host to compliance with a
baseline
How are VMs remediated?
Automatically
Through a VirtualCenter scheduled task
Manually
Using Inventory->Virtual Machine->Remediate…
By right-clicking host, or VM and selecting “Remediate…”
13
VMware Confidential
Remediate Against a Baseline
Baseline remediation
ensures that all VMs
in a group have had
all updates in a
baseline applied
Select between
applying baselines or
specific updates
14
VMware Confidential
Remediate Against Specific Updates
An update remediation allows for application of single updates.
15
VMware Confidential
Specify Remediation Rollbacks
Snapshot creation
and deletion can
be included as
part of the
remediation
operation
Saves VM state in
case a patch
causes problems
and requires a
rollback to the
unpatched state
16
VMware Confidential
Schedule the Remediation
Remediation can be
scheduled to minimize
impact to the user
Dates, times configurable
Specific actions can be
performed based on VM
state (on, off, suspended)
17

VMware Confidential
Distributed Power Management
(Experimental)
Distributed Power Management (DPM)
Reduce data center power consumption by having DRS consolidate
loads during non-peak hours and powering down the inactive hosts
The goal is to minimize total power consumption while still providing
enough resource capacity to satisfy total resource demand, plus
some user-specifiable amount of reserve capacity
Provides customers with significant cost savings from reduced power
consumption
Business Demand

Confidence level
Based on the number of performance samples that VC has collected
As VC collects more performance samples the confidence goes up
36
VMware Confidential
Plan Consolidation
Choose “Plan Consolidation”
List of analyzed systems presented
For each system, drop-down menu of candidate destination ESX
Server Hosts
37
VMware Confidential
Destination Server Suitability
Star rating
Based on compatibility with ESX Server host
Each candidate destination host gets a separate star rating
Compatibility is considered for things such as sufficient
number of CPUs, ability to run the guest OS etc.
Rating based on the average CPU & Memory usage and
disk space of the destination host
The lower the resource usage, the higher the star rating.
The networking check only verifies the number of NICs, not
network usage

Storage VMotion
VMotion vs. Storage VMotion
VMotion - Moves a running VM
from one ESX server to another
ESX server leveraging shared
storage
The storage resource stays in the
same storage location
Storage VMotion - Moves the disk
resources for a VM from one
datastore to another datastore
The VM stays up and running on
the same ESX Server
46
VMware Confidential
Storage VMotion
Migrate running VM to new storage
VM stays on same host
VM disks may be individually placed
Storage type independent
Migration does not disturb VM
No downtime
Transparent to guest OS and apps
Minimal performance impact
47
VMware Confidential
Storage VMotion – Use Cases
Storage maintenance and upgrades
ESX Server upgrades that change disk
format
More flexible Information Lifecycle
Management (ILM) solutions
Improved performance troubleshooting
Storage consolidation/reclamation
LUN reconfiguration
48
VMware Confidential
What Storage VMotion Moves
VM’s “home” directory
Config file (vmx)
Logs
Swap file (vswp)
Snapshots
Other misc files
config
swap
disks
logs
Virtual Machine
VMFS volume
VM disks (vmdk)
Treat disks separately to support
independent placement
49
VMware Confidential
Storage VMotion: VM Home Relocation
Copy non-virtual disk files to new VM home
Use NFC (NetWork File Copy)
Switchover VM to using new files
Use VMotion
Start up new VM on same host instead of different host
New VM uses config file in new VM home directory (similar to
VMotion in ESX 2.x)
Same host VMotion known as “self-VMotion”
50
VMware Confidential
Storage VMotion: Virtual Disk Relocation
Uses disk relocation feature from Upgrade VMotion
Uses snapshot technology to move virtual disks

Snapshot VM disks to create child disks

Copy read-only base disks to new location

Commit disk snapshot into copied base disks
Each virtual disk can be placed independently
Location can be different than VM home or other VM disks
Can also stay in current location

Storage VMotion Requirements
Use of Storage VMotion requires…
Temporary doubling of VM’s cpu/mem resources
Two copies of the VM exist simultaneously on single host
Each VM uses memory and has its own cpu/mem reservation
VMotion interface must be configured properly
Does not require a physical link
Intrahost “network” connection between the two VMs
Must not be using a device that prevents VMotion
54
VMware Confidential
Storage Vmotion in 3.5 limitations
No GUI Interface. CLI only
Can't simultaneously change execution host
No snapshots
Requires double resource reservation consumption
Two copies of the VM need to be run on the same ESX server at
one time while the storage migration process is taking place
Can't move disks without moving the VM home directory too
Limitations to be lifted in future releases
