ESXi Convergence

• The Console OS has been removed.

• The VMware agents run directly on the vmkernel.

• Infrastructure services are provided natively through modules included with the vmkernel.

• Only modules that have been digitally signed by VMware are allowed on the system, creating a tightly locked-down architecture.

ESXi 5 Image Deployment

Image builder/factory• Customizes ESXi ISO images

• Combines ESXi image with updated vendor specific drivers,modules and profiles

AutoDeploy / Stateless ESXi • PXE Boot from Network - No hard disk needed to boot ESXi

• Allow for extensibility and cost reductions in customer environments

• Allow for extensibility and cost reductions in customer environments

• Updating or rebuilding is as simple as rebooting the server

Controlled by:

• Image Profiles (vendor specific modules and drivers)

• Host Profiles (storage, network and security policy configurations)

• Answer Files (non-interactive install/boot)

• Runtime state (in vCenter)

What’s new with High Availability?

HA Replaced by Fault Domain Manager (FDM) • We are no longer using AAM for HA functionality

• This changes things substantially:

� No more Primary/Secondary agent model

� A single Log file (fdm.log)

� Storage Heartbeating (in addition to network pings)

� Cluster configuration in ~1Min (as oppose to ~1min per host)

� HA State with Description:

What’s new with vMotion?

VMware VMotion• Multi-NIC support allowing the use of up to 4-10Gbps NICs or 16-1Gbps NICs

• Support for Higher Latency Links (up to 10ms)

• Improved error reporting

• vCenter will have better error reporting:

11 Confidential

What’s new with Storage vMotion?

VMware Storage VMotion

• Mirrored Storage vMotion – New architecture leveraged technologies provide as much as 2x improvement in performance since 4.0� Guarantees migration success even when facing a slower destination

� More predictable migration time (and shorter)

• Migrating snapshots is now supported!

What’s new with Storage?

VMFS 5• Scalability and performance (benchmarked 1,000,000 IOPs from ESXi 5 host)

• Increase limits of the file-system (Limits α FS size that increases when FS extends/grows)

• 2TB+ device support on VMFS 5

• Support for 64TB RDMs

•

Hardware Restrictions

• ESXi only supports latest v3 of Xserve hardware, check HCL.

� May run on other hardware, but not supported or tested

• A VM with OSX will not boot/run on non-apple hardware

� OS checks keys on virtual SMC at boot, which obtains keys from an esx host driver

� An OSX VM can be created/configured on any type of hardware.

• vSphere will block vmotion of an OSX VM to non-apple hardware

21 Confidential

• vSphere will block vmotion of an OSX VM to non-apple hardware

OS Restrictions

• Server variant only due to EULA

• Leopard 10.5.8+ or Snow Leopard 10.6.0+

• Both 32 and 64 bit.

• Tested up to 16 vCPUs (max available on Xserve today)
