 Enhanced User Interface
 Enhanced Deployment Mechanism
©2009 Varrow, Inc. - CONFIDENTIAL
vSphere HA Primary Components
•Every host runs an agent
– Referred to as ‘FDM’ or Fault Domain
Manger
– One of the agents within the cluster is
chosen to assume the role of the Master
ESX 01
ESX 03
ESX 02
ESX 04
• There is only one Master per cluster during
normal operations
– All other agents assume the role of Slaves
•There is no more Primary/Secondary
concept with vSphere HA
vCenter
©2009 Varrow, Inc. - CONFIDENTIAL
vCenter Communications
• VC communicates with the Master primarily
– Once a Master is elected and contacts vCenter,
vCenter sends a compatibility list to the Master.
The Master saves this on a local disk, then pushes
it out to the other hosts in the cluster.
– vCenter also communicates with the Master to
update changes to VM states and configuration
information.
ESX 01
ESX 03
ESX 02
ESX 04
• vCenter may communicate to the Slaves in certain
situations, such as:
• Scanning for a existing Master
• If the Master states that it cannot reach a
Slave. In this case, vCenter will try to contact
the Slave to determine why.
• When powering on a FT Secondary VM
• When host is reported isolated or partitioned.
vCenter
©2009 Varrow, Inc. - CONFIDENTIAL
Storage Level Communications
• One of the most exciting new features of vSphere HA
is its ability to use a storage subsystem for
communication.
• The datastores used for this are referred to as
‘Heartbeat Datastores’.
• This provides for increased communication
redundancy.
• Heartbeat datastores are used as a communication
channel only when the management network is lost
- such as in the case of isolation or network
partitioning.
vCenter
©2009 Varrow, Inc. - CONFIDENTIAL
ESX 01
ESX 03
ESX 02
ESX 04
Failure Scenarios – Network Partition
•Occurs when:
– Master can see heartbeat datastores
– Master can not reach hosts over the
management network.
 Results in:
• A Master in each partition
• VMs in other partition are:
ESX 01
ESX 03
ESX 02
ESX 04
• Monitored via the storage subsystem
• Restarted after a host of VM failure
• vCenter will only report the state of one of the
Masters
• When the situation is resolved, the
Masters communicate and one is
chosen to be the Master.
vCenter
©2009 Varrow, Inc. - CONFIDENTIAL
Failure Scenarios – Host Network Isolation
•Occurs when:
– Host is partitioned from the Master and
sees no vSphere HA network traffic
– The host can not ping the isolation address
ESX 01
ESX 03
ESX 02
ESX 04
 Results in:
• Isolation response applied (if configured and the
Master can restart the VMs)
• VMs left running are monitored via the storage
subsystem and restarted as needed
• Note the default isolation response has been
changed to Leave Powered On

Storage vMotion - Introduction
•In vSphere 5.0, a number of new enhancements were
made to Storage vMotion.
– Storage vMotion will work with Virtual Machines that have snapshots,
which means coexistence with other VMware products & features
such as VCB, VDR & HBR.
– Storage vMotion will support the relocation of linked clones.
– Storage vMotion has a new use case – Storage DRS – which use
Storage vMotion for Storage Maintenance Mode & Storage Load
Balancing (Space or Performance).

What does Storage DRS provide?
•Storage DRS provides the following:
1.
2.
3.
•
Initial Placement of VMs and VMDKS based on available space and I/O
capacity.
Load balancing between datastores in a datastore cluster via Storage
vMotion based on storage space utilization.
Load balancing via Storage vMotion based on I/O metrics, i.e. latency.
Storage DRS also includes Affinity/Anti-Affinity Rules for
VMs & VMDKs;
• VMDK Affinity – Keep a VM’s VMDKs together on the same
datastore. This is the default affinity rule.
• VMDK Anti-Affinity – Keep a VM’s VMDKs separate on different
datastores
• Virtual Machine Anti-Affinity – Keep VMs separate on different
datastores
•Affinity rules cannot be violated during normal operations.
©2009 Varrow, Inc. - CONFIDENTIAL
Datastore Cluster
•An integral part of SDRS is to create a group of datastores called a
datastore cluster.
• Datastore Cluster without Storage DRS – Simply a group of datastores.
• Datastore Cluster with Storage DRS - Load Balancing domain similar to a
DRS Cluster.
•A datastore cluster , without SDRS is just a datastore folder. It is the
functionality provided by SDRS which makes it more than just a
folder.

datastores
Storage DRS Operations – Initial
Placement
Initial Placement - VM/VMDK create/clone/relocate.
•When creating a VM you select a datastore cluster rather than an
individual datastore and let SDRS choose the appropriate datastore.
•SDRS will select a datastore based on space utilization and I/O load.
•By default, all the VMDKs of a VM will be placed on the same
datastore within a datastore cluster (VMDK Affinity Rule), but you
can choose to have VMDKs assigned to different datastore clusters.

datastores
Storage DRS Operations – Load Balancing
Load balancing - SDRS triggers on space usage & latency
threshold.
• Algorithm makes migration recommendations when I/O response time and/or space
utilization thresholds have been exceeded
– Space utilization statistics are constantly gathered by vCenter,
default threshold 80%
– I/O load trend is currently evaluated every 8 hours based on a
past day history, default threshold 15ms
• Load Balancing is based on I/O workload and space which ensures that no
datastore exceeds the configured thresholds.
•Storage DRS will do a cost / benefit analysis!
•For I/O load balancing Storage DRS leverages Storage I/O
Control functionality
©2009 Varrow, Inc. - CONFIDENTIAL
So what does it look like? Load Balancing
•It will show “utilization before” and “after”
•There’s always the option to override the
recommendations

What are vStorage APIs Storage Awareness
(VASA)?
• What are vStorage APIs Storage Awareness (VASA)?
• VASA is an Extension of the vSphere Storage APIs,
vCenter-based extensions. Allows storage arrays to
integrate with vCenter for management functionality via
server-side plug-ins or Vendor Providers.
• This in turn allows a vCenter administrator to be aware
of the topology, capabilities, and state of the physical
storage devices available to the cluster.
• VASA enables several features.
• For example it delivers System-defined (array-defined)
Capabilities that enables Profile-driven Storage.
• Another example is that it provides array internal information
that helps several Storage DRS use cases to work optimally with
various arrays.

vSphere Storage Appliance
(VSA)
Introducing the vSphere Storage Appliance (VSA)
We are basically providing our customers with a low cost, easy to deploy storage
appliance which will provide shared storage.
• The VSA Manager installation/configuration steps are fool-proof, meaning that an
administrator without any SAN skills can deploy it quickly & painlessly. This is a
really cool selling point when compared to some other VSAs on the market.
•
The VSA creates shared storage out of local storage for use by a specific set of
hosts.
•
This means that vSphere HA & vMotion can now be made available on low-end
(SMB) configurations, without external SAN or NAS servers.
• The vSphere Storage Appliance can be deployed in two configurations:
– 2 x ESXi 5.0 servers configuration
• Deploys 2 vSphere Storage Appliances, one per ESXi server & a VSA
Cluster Service on the vCenter server.
– 3 x ESXi 5.0 servers configuration

vSphere Storage Appliance (VSA) How it Works

•Each ESXi server has a VSA deployed to it as a Virtual Machine.
•The appliances use the available space on the local disk(s) of the
ESXi servers & present one replicated NFS volume per ESXi server.
This replication of storage makes the VSA very resilient to failures.

3 typical use-cases for SRM
Disaster Failover
Recover from unexpected site
failure
• Full or partial site failure
The most critical but least
frequent use-case
• Unexpected site failures do
not happen often
• When they do, fast recovery is
critical to the business
©2009 Varrow, Inc. - CONFIDENTIAL
Disaster Avoidance
Planned Migration
Anticipate potential datacenter
outages
• For example: in case of
planned hurricane, floods,
forced evacuation, etc.
Most frequent SRM use case
• Planned datacenter maintenance
• Global load balancing
Initiate preventive failover for
smooth migration
• Leverage SRM ‘planned
migration’ to ensure no dataloss
• ‘Automated failback’ enables
easy return to original site
Streamline routine migrations across
sites
• Test to minimize risk
• Execute partial failovers
• Leverage SRM ‘planned migration’
to ensure no data-loss
• ‘Automated failback’ enables bidirectional migrations
