But it is completely dependant on the equipment you have available. The best way to run this would actually be to use stack cables in the back so that the switches work as a single unit. But I'm not sure if stack ports are available on the Nexus 5000 rack switches.Anonymoushttps://www.blogger.com/profile/09446789446147061862noreply@blogger.comtag:blogger.com,1999:blog-3331505015741725494.post-70989995044464125512013-02-13T09:56:49.415-08:002013-02-13T09:56:49.415-08:00This may be a dumb question, but how are the links...This may be a dumb question, but how are the links between the two switches configured?

This design highlights an optimal guarantee where one type of traffic will absolutely not impact any other. You can do a similar design using 2 x 10GbE uplinks, if you search on google for VMware Networking Blog you will find information around this. If you are using unmanaged switches then they will not be capable of VLAN segmentation. It will work, but it will not be anywhere near as secure as I personally like it to be.Anonymoushttps://www.blogger.com/profile/09446789446147061862noreply@blogger.comtag:blogger.com,1999:blog-3331505015741725494.post-66223891511669365462012-07-11T13:11:30.082-07:002012-07-11T13:11:30.082-07:00Hi Paul,

So if it is not supported then VMware has got big problems. They might not like using Jumbo Frames across the entire network as this is one of the main historical reasons for keeping the storage vSwitch separate from the rest.<br /><br />http://blogs.vmware.com/networking/2011/12/vds-best-practices-rack-server-deployment-with-two-10-gigabit-adapters.htmlAnonymoushttps://www.blogger.com/profile/09446789446147061862noreply@blogger.comtag:blogger.com,1999:blog-3331505015741725494.post-69110400722634203962012-05-16T02:03:43.113-07:002012-05-16T02:03:43.113-07:00Hi,

We frequently have difficulties with VMWare engineers going on about it being unsupported. <br />They really don't like us mixing iSCSI with other traffic on the same vswitch. Do you have any reference to this being an OK configuration according to VMware ?<br /><br />Regards<br />Carl.Anonymousnoreply@blogger.com
