Windows 2012 Hyper-V Advanced Network Security : DHCP Guard, Router Guard, Port Mirroring

November 27, 2012 5 comments

Windows 2012 Hyper-V brought a lot of new features. There are many improvements in security as well:

DHCP Guard is a security feature that drops DHCP server messages from unauthorized virtual machines pretending to be DHCP servers.
Router Guard is a security feature that drops Router Advertisement and Redirection messages from unauthorized virtual machines pretending to be routers.
Port Mirroring duplicates all egress and ingress traffic to/from one or more switch ports (being monitored) to another switch port (performing monitoring)

These settings are configured per Virtual Machine and Virtual Switch. To configure :

  1. Open the Hyper-V Manager and then select the Virtual Machine (e.g. W2012-FS01)
  2. On the right panel, click on Settings.
  3. Select the Virtual Switch (e.g. v-External-Wired) you want to configure and expand Advanced Features.

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.
