i was reading this dell PE R720 spec on the web site and got bit cofused about this GbE term.
it says 2 quard port 1GBE Base -T and2 * Dual port 10GbE  nic cards. But i see on the diagram of total of 4NIC sockets
is not it suppose to have more than 4 sockets?

Do you have the saved cart or a screen shot of the server you were building. The R720 is a base part number. I need to know how you were configuring it.

There should be 8 1gb Nic Ports and 4 10gb Nic

Base the R720 comes with a Quad port 1 Gbe NIC, which means it has 4 NIC ports standard.

There are other NICs you can order, a few are quad port 1 Gbe cards and a few are dual port 10 Gbe cards.

From the specs I read out:

Embedded NIC
- (4 ports) Broadcom® Quad Port 1GbE BASE-T (no TOE or iSCSI offload)
- (4 ports) Intel Quad Port 1GbE BASE-T (no TOE or iSCSI offload)
- (2+2 ports) Intel Dual Port 10GbE BASE-T with 2 x 1GbE (FCoE capability enabled on the 10GbE ports)
- (2+2 ports) Broadcom Dual Port 10GbE SFP+ with 2 x 1GbE (TOE and iSCSI offload available on 10GbE ports)

It does not say "...xy nic cards", but rather "...xy ports". They are embeded onto mainboard, not PCIe card adapters (which would occupy PCIe slots...and not sockets - CPU has socket, to be strict with terminology ;-))


...and for the latest R720 series:
- Broadcom® 5720 Quad Port 1GbE BASE-T(no TOE or iSCSI offload)
- Intel I350 Quad Port 1GbE BASE-T(no TOE or iSCSI offload)
- Intel X540 Dual Port 10GbE BASE-T with 2 x 1GbE(FCoE capability enabled on the 10GbE ports)
- Broadcom 57800S Dual Port 10GbE Base-T with 2 x 1GbE(TOE and iSCSI offload available on 10GbE ports)
- Broadcom 57800S Dual Port 10GbE SFP+ with 2 x 1GbE(TOE and iSCSI offload available on 10GbE ports)

Which means, in any case there are 4 ports, which you may choose upon configuring new server, which type they will be of.
Of course, you may add additional cards in configurator, but I am talking about MINIMUM configuration available via configurator.

Lapsy,
You are correct there are only 4-physical sockets.
I am confused about the physical connections when we have more than 4 subnets.
For  an example in VMware.
We have Vmotion on one subnet.
Iscsi in another subnet
Console in an another subnet.
Vnetowk in another subnet
We need 5 physical sockets to uplink the above ?
But here we have 4 sockets.
In case if we need HA where do we go for physical connections?

Do we have to do something on switch ?

Pdsmicro,

Vlans.

Here is how I would set it up.


Lan Ports 1 and 2 - iSCSI Dedicated
Lan Ports 3 and 4 - LAN Dedicated
Lan Ports 5 and 6 - VLAN Trunk Ports (Vmotion Vlan, Vcenter Vlan, etc)

Physical connection have nothing to do with IP subnets.

Each subnet should be its own VLAN.

You can have multiple VLAN's assigned to a physical connection.  

In the switch you assign multiple tagged VLAN's to the port(s) you want to the traffic to flow over.

In VMWare you would create a VSWitch, map one or more physical NIC's to it and also do VLAN tagging.

Normally you would team two or more physical NIC's and switch ports and do VLAN tagging so that there is not a single point of failure.

Thank you for your reply. I have question on the VLAN tagging
I do not know about switches.
I know we have vlan 10 and 20 ,30 on switches.
Is it the vlan id we have to put in VSwitch in VM?

Yes, the Same VLAN ID on the switch is what you use in Vswitch. Make sure that the physical switch ports on the switch are set for Trunk Mode.

"trunk mode" is Cisco's term for allowing multiple vlans to go over a single port.  

On some other switches "trunk" is what they use for link aggregation or what Cisco calls Etherchannels.

I don't think other switches have a special term for ports that allow multiple VLAN's.

Correct Trunk on Cisco, I believe "Access" on HP and Dell.

For the best redundancy I suggest you use:
- the 4 default ports embedded on mainboard
- plus additiona PCIe card with 4 ports of the same type, as on mainboard

The 1 Gbit iSCSI for storage... well, with today's demands I would NOT recommend it. Use Fibre Chanel ports, or even better, go with 10GbE NFS or 10GbE FCoE, which are by my oppinion protocols for next years. Shared storage I/O demads are huge and will not lower in future, so get yourself equipped well.
