Que sistemas operativos soportan VMXNET ? ...no todos

• VMXNET 3 — The VMXNET 3 adapter is the next generation of a paravirtualized NIC designed for performance, and is not related to VMXNET or VMXNET 2. It offers all the features available in VMXNET 2, and adds several new features like multiqueue support (also known as Receive Side Scaling in Windows), IPv6 offloads, and MSI/MSI-X interrupt delivery.
  
  VMXNET 3 is supported only for virtual machines version 7 and later, with a limited set of guest operating systems:
  
  • 32- and 64-bit versions of Microsoft Windows XP,7, 2003, 2003 R2, 2008, and 2008 R2
  • 32- and 64-bit versions of Red Hat Enterprise Linux 5.0 and later
  • 32- and 64-bit versions of SUSE Linux Enterprise Server 10 and later
  • 32- and 64-bit versions of Asianux 3 and later
  • 32- and 64-bit versions of Debian 4
  • 32- and 64-bit versions of Ubuntu 7.04 and later
  • 32- and 64-bit versions of Sun Solaris 10 U4 and later
    
  Notes:
  • Jumbo frames are not supported in Solaris Guest OS with VMXNET 2 or VMXNET 3.
  • Fault Tolerance is not supported on a virtual machine configured with a VMXNET 3 vNIC in vSphere 4.0, but is fully supported on vSphere 4.1.

Nuevo TR: NetApp Storage Best Practices for VMware vSphere 5

Nuevo documento de December 2011 actualizado tambien a la version vSphere 5 (ESXi)

Lo podeis descargar del siguiente enlace: http://media.netapp.com/documents/tr-3749.pdf

Del documento destacaria la referencia al "Storage DRS" con los "Datastore Cluster" de la nueva version vSphere 5, y las recomendaciones sobre su configuracion:

Following are the key recommendations when configuring storage DRS and datastore cluster:
- Set SDRS to manual mode and to review the recommendations before accepting them.
- All datastores in the cluster should use the same type of storage (SAS, SATA, and so on) and have the same replication and protection settings.
- SDRS will move VMDKs between datastores, and any space savings from NetApp cloning or deduplication will be lost when the VMDK is moved. You can rerun deduplication to regain these savings.
- After SDRS moves VMDKs, it is recommended to recreate the Snapshot copies at the destination datastore.
- Do not use SDRS on thinly provisioned VMFS datastores due to the risk of reaching an out-of-space situation.
- Do not mix replicated and nonreplicated datastores in a datastore cluster.
- All datastores in an SDRS cluster must either be all VMFS or all NFS datastores.
- Datastores cannot be shared between different sites.
- All datastore hosts within the datastore cluster must be ESXi 5 hosts.
