Hyper-V , XenServer, vSphere Comparison : Scalability,Performance;Density

November 12, 2012 6 comments

Some folks are asking me about Citrix and Hyper and VMware comparison :

Scalability,Performance;Density

1.XenServer 6.0 active VMs per host varies based on Server/VDI workload, with PVS/IntelliCache & HA on/off

2.Maximum VMs on a Cluster (Resource Pool) on XenServer 6.0 based on a maximum of 50-60 concurrent protected VMs per host with HA enabled.
3.Host physical memory is capped at 32GB thus maximum VM memory is also restricted to 32GB usage.
4.For clustering/high availability, customers must purchase vSphere
5.vSphere 5.0 Enterprise Plus is the only edition that supports 32 vCPUs.  All others support 8 vCPUs within a virtual machine.
6.Maximum number of Virtual CPUs per Host is not documented in the Citrix XenServer 6.0 Configuration Limits documentation.

High Availability & Resiliency

1.XenServer 6 provides Automated VM Protection & Recovery in the Advanced edition and higher
2.XenServer 6 provides a Site Replication capability in the Platinum edition, however replication is provided by a storage vendor, not inbox from XenServer hosts.
3.XenServer 6 provides HA in the Advanced edition or higher.
4.The vSphere Hypervisor has no high availability features built in – vSphere 5.0 is required.
5.VMware Data Recovery is available in Essentials Plus and higher vSphere 5.0 editions
6.vSphere Replication is a feature of VMware vCenter Site Recovery Manager (SRM), which is available in 2 editions and is a chargeable addition to vSphere 5.0
7.VMware HA is built in to Essentials Plus and higher vSphere 5.0 editions
8.VMware have made APIs publicly available, but actual application monitoring is not included
9.Features available in all editions that have High Availability enabled.

 

1.Maximum VMs on a Cluster (Resource Pool) on XenServer 6.0 based on a maximum of 50-60 concurrent protected VMs per host with HA enabled.
2.High Availability/vMotion/Clustering is unavailable in the standalone vSphere Hypervisor
3.VMware does not support VM Guest Clustering using iSCSI storage.
4.VMware does not support VM Guest Clustering using File Based Storage i.e. NFS
5.VMware does not support the vMotion of a VM that is part of a Guest Cluster
6.VMware does not support the use of Memory Overcommit with a VM that is part of a Guest Cluster
7.No XenServer documentation can be found that details the number of simultaneous live migrations over either 1GB or 10GB Ethernet.

Windows 2012 Hyper-V VHDX Disk format : Why should you convert your VHD to VHDX and how (Step by Step)

October 30, 2012 4 comments

Although this topic is not new I had some readers asking me about it. So here we go…

Windows 2012 Hyper-V has a new disk format : VHDX.

VHDX principal features

  • Storage capacity up to 64 terabytes (TBs). With the VHDX format we can to create larger virtual hard disks ( up to 64TB). The VHD format has a 2 TB limit to VHD’s.
  • Corruption protection during power failures
  • Optimal structure alignment for large-sector disks (4K sector aligned virtual hard disk), which increases the performance. Why Windows Server 2012 Hyper-V VHDX 4K Alignment Is So Important
  • Trim/Unmap – Space efficiency on VHDX files as well as the host disk
  • Thin provisioning
  • Ability to store custom metadata about the file that the user might want to record, such as operating system version or patches applied

You can convert a VHD into VHDX and vice versa. As long the size limit for the VHD is respected:

  • Shutdown the Virtual Machine
  • Double check if there is NO Snapshots
  • Double check if there is NO replication enabled
  • On the Hyper-V Manager,  on the left pane select Edit Disk…

  • Click on Next
  • On the Edit Virtual Disk Wizard, type the name and location of your existing VHD file or click on Browse to locate

  • Click on Next
  • On the Choose Action page select Convert and then click Next

  • On the Choose Disk Format page select VHDX and click Next

  • On the Choose Disk Type page select Disk type : Fixed or Dynamic  and then click Next

  • On the Configure Disk page type the destination path and then click Next

  • On the Summary page, click Finish to start the process. The process time depends on the VHD size.
