Monolithic vs. MicroKernelized• Monolithic hypervisor

– Simpler than a modern kernel, but still complex

– Contains its own drivers model

• Microkernelized hypervisor– Simple partitioning functionality– Increase reliability and minimize TCB– No third-party code– Drivers run within guests

Storage OptionsVirtual Hard Disk

Supports both Synthetic and Emulated devicesThree Types VHD file formats:

FixedDynamicDifferencing

Supports Pass-Thru disk Attaching to raw physical disk or LUNHigh performance and larger storage (beyond 2TB VHD file limit)

Disk Access Options: IDE, SCSI, ISCSIOnly can boot from IDE disk ISCSI4 IDE Disks and 256 SCSI Disks

Other Performance Tuning Options to Consider

Processor: Larger processor cache is better.

Memory: The quantity of RAM is a more important factor than RAM speed or latency.

Network:Use multiple NICs and multi-port NICs on each host server.Dedicate one NIC/Port on each host server for network I/O and management of the host itself and do not create a virtual switch using that NIC.Dedicate one NIC/Port on each host server to the private (heartbeat) network if the host is part of a server cluster.Dedicate at least two NICs/Ports on each host server to the iSCSI network if an iSCSI storage architecture is being utilized.Dedicate at least one NIC/Port on each host server for guest virtual machine network I/O. For maximum consolidation ration, utilize one or more 10-Gigabit Ethernet NICs to virtual machine network I/O.

Storage:If direct attached storage is being utilized, a SATA II or SAS RAID controller internal to the server is recommended as previously discussed. If a storage array and SAN are being utilized, host bus adapters (HBAs) are required in the host server.Periodically defragmenting, pre-compacting, and compacting the VHD files on the guest and defragmenting the volumes on the host will help ensure optimal disk I/O performance.

VM

• Maximize Resources– Centralized virtual machine deployment and management

for Hyper-V, Virtual Server, and VMware ESX servers– Intelligent placement of Virtual Machines– Fast and reliable P2V and V2V conversion– Comprehensive application and service-level

monitoring with Operations Manager– Integrated Performance and Resource Optmization (PRO) of VMs

• Increase Agility– Rapid provisioning of new and virtual machines with templates– Centralized library of infrastructure components– Leverage and extend existing storage infrastructure and clusters– Allow for delegated management and access of VMs

• Leverage Skills– Familiar interface, common foundation – Monitor physical and virtual machines from one console – Fully scriptable using PowerShell

SummaryOver a dozen hosters already offering Hyper-v based offersOn avg: 12 hosts/server

Quad core + dual proc + 16-32 G RAMMost successful offering till date:

14 node cluster with 15 VMS/nodeAverage time to create offer

4 weeks for stand alone8 weeks for highly available

New System Center Licensing costs make managed hosting a very appealing optionIf interested, 90% of code is available in HDA
