The e1000e and fiber NICs

I have some hardware that I'm repurposing which includes a box that has 82546GB based controllers on it. Two of these controllers are copper and four are fiber:
04:02.0 Ethernet controller: Intel Corporation 82546GB Gigabit Ethernet Controller (rev 03)
04:02.1 Ethernet controller: Intel Corporation 82546GB Gigabit Ethernet Controller (rev 03)
06:02.0 Ethernet controller: Intel Corporation 82546GB Gigabit Ethernet Controller (rev 03)
06:02.1 Ethernet controller: Intel Corporation 82546GB Gigabit Ethernet Controller (rev 03)
07:02.0 Ethernet controller: Intel Corporation 82546GB Gigabit Ethernet Controller (rev 03)
07:02.1 Ethernet controller: Intel Corporation 82546GB Gigabit Ethernet Controller (rev 03)
The problem is I can't seem to get the fiber interfaces to light up. I've tried the stock drivers as well as the source downloaded from Intel (version 1.3.17). Whenever I unload the e1000 driver (of which works correctly with the copper ports) and load up e1000e I get no interfaces. Any thoughts on where to look next?
Here's one of the copper interfaces from an lshw output:

How to utilize T5-4 vswitch setup to utilize 10GbE dual 2x NICs

Hi,
In Solaris 10 update 11
Have setup one virtual LDom control-domain with four virtual ldom guest-domains on T5-4 which has 1Gb (10000MB) Ether NICs and two 2x10GbE Fiber SFP+ NICs(512 cpus, 1TB ram), each with their own vdisk. Setup one vswitch for primary but speed is only 1Gb between domains for the one vswitch linked to the 1GbE physical NIC MAC. Want to utilize the 10GbE NICs in a vswitch for these LDoms. Found doucment ID Verify Ethernet address for LDOM 1020017.1 but it ducusses the nxg0 add-in dual NIC card, 'hybrid' mode and using the nxg0 MAC, not using the T5 auto-assign function for MACs. Will doc 1020017.1 work for T5 platforms and vswitch setup to utilize their 10GbE fiber NIC as a vswitch? Also wanting feedback on 'hybrid' mode for the 10GbE fiber NIC in vswitch setup, its benefits or challenges in this mode setting.
How do, can we utilize the 10GbE NIC in a vswitch creation for the 10GbE fiber NICS for these four guest-domains?
Thanks,
JC

Hi
Hybrid mode is only for the 10 Gbit Ethernet circuits integrated into the T2 SPARC chip and T4 SPARC chip.
No other SPARC chips have the integrated 10 Gbit XAUI Ethernet ports. If you have T5 servers and you need fast DMA ethernet between a LDOM and the world outside the system, the new way to do this is with the SingleRoot InputOutput Virtualization ( SR-IOV ) that is now available. the Sun dual 10 GbE fiber card can support 64 SR-IOV connections.
See:
SR-IOV Overview - Oracle VM Server for SPARC 3.1 Administration Guide

Gigabit Fiber Card compatibility

Could someone tell me if the following configuration will work?
Gigabit Fiber NIC card in server connecting to a Gigabit Switch (Cisco Catalyst-6513 w/ WS-X6516-GBIC module) which connects to the primary 10/100 Switch.
Thanks.

Yes, that will work, but make sure you have the same flavour of Gigabit fiber in the NIC and the GBIC. Usually for a server NIC it will be 1000BaseSX.

Dot1x protocol with fiber inerface

hello,
Is dot1x protocol works well with the fiber interface (1G)?
The connection between the PC (fiber NIC) to the switch will only be through fiber.
If yes, is it work with all kinds of switches (6500,3750,3560....)?
thanks...

Hi. 802.1x is supposed to work with ethernet interfaces no matter if they're copper or fiber.

Fiber Card failed

Dear Guru
Hope you may give me some information about the problem.
Our company SAP is ECC6.0 running on AIX 5.3 with oracle database.
Few day ago, the server log showed one of the fiber NIC card on our development server was failed. I already arranged the hardware vendor to come down to change the device next week, but before that, may anyone confirm with me whether the hardware key will be updated by replacing a new fiber NIC card? And do I need to reactiviate the SAP again?
Thanks
guodong

Hi,
If fiber card fails then hardware vendor has to play the key role. After he replaces the card he may have to change the WWN number at the EVA side . One he was able to mount the file systems with the same data then there is no need to check at SAP side. Only thing yo have to monitor the SAP application completely. Also check the run the DB verify in DB13 for any block corruptions.
Thanks,
Chaitanya

V490 pci slot (64 bit) backwards compatible with 32 bit card?

As the subject states I have a pair of SunFire V490's that I need to put 32 bit fiber NIC's in. (Reason for 32 bit cards is that it is a one way solution and the company has not updated their tech www.owlcti.com )
It is my understanding that 64/32 bit cards/slots are usually interchangeable they just run at 32. Any help on the matter is greatly appreciated.

Hi George,
Thank you for responding.
Is the hot-plug issue just with all of your PCI cards or just some? I have two NI PCI-6514 cards in hot-plug slots that show up in the NI Measurement & Automation Explorer. Unfortunately, I have yet to test the I/O functions of the cards.

PIX keeps reboot

I have a PIX525. It keeps rebooting. I have gone to the monitor and tftp the pix803.bin file back to the flash for few times. Sometimes it will stop at reinitialize flash and then reboot, sometimes it read the image half way, then reboot.
I think the flash is corrupted. Is there any way to format or erase the flash in monitor mode. Or there is any way to stop rebooting?

But my secondary PIX is in the same place, so I think it is nor temperature related. I had missed the my own post, it you read my last first post, you will see

under PCI device table. I think one of the Intel fiber NIC is not comparable is the PIX.
But both fiber cards were unplugged from the IBM servers, I don't know why one works, why the other failed. In fact, I tried more fiver cards, most of them causes the PIX reboot.

Server 2003 R2 Crippled after latest WSUS updates

I'm posting this because I'm stuck with a problem that has affected all Windows Servers (both 2003 and 2008) that I've installed the latest group of WSUS patches on.
After installation of these updates, the server hangs on restart at "Applying computer settings...". It hangs at that dialogue for between one and two hours. Eventually if I'm patient I can get to the desktop, but the server is incredibly slow.
One of my servers can't be logged onto and is hung at "Logging off..." after I attempted to restart it through the Windows interface.
This has also affected several of my Server 2008 servers, but eventually I was able to log onto them, then shut them down, then when they started back up they seem to be functioning normally.
It appears I am able to restart in Safe Mode, so if there are any suggestions as to a fix that can be implemented in Safe Mode that is an option.
Has this happened to anyone else and is there anything I can do to get my servers back in operation?

A little update from today.
This is a closed network not connected to the WWW so I am unable to post any config info. I have the physical server back up but the virtual server is only partly working (I have a work around that lets me log on locally).
To refresh, these are both Server 2003 R2 Ent. One is physical and is DC/AD/DNS. The other is virtual, is a web server, and is hosted on ESXi 4.1. Servers were performing normally until a group of 6 WSUS updates were applied. Once that happened and the servers
were restarted, they both would hang at the "Applying computer settings..." screen and stay there for days. Some services would still be available to the network and others were not (IIS still worked on the web server).
What I did today on the physical server:
1. Cold booted with network adapter disconnected - result: no change
2. Booted into Safe Mode and removed all updates that were applied last from WSUS - result: no change
3. Booted into Safe Mode and disabled the service Network Location Awareness - result: server would complete boot up and let me log in normally, but NIC was not functioning (it's a single NIC). I was able to enable the Network Location Awareness service
but the NIC was still not functioning, no network connectivity (tried to repair through Windows, no change)
4. Then while logged on, disconnected the network adapter cable from the NIC and plugged it back in, and then it seems the NIC started working again.
All servers, both physical and virtual, connect to a 12 port Cisco 3750 using MM fiber NICs.
On the virtual server with this problem, I did not remove the WSUS updates that were applied. I booted it into safe mode, disabled the Network Location Awareness service but it would not boot normally until I removed the virtual NIC through ESXi.
Once the virtual NIC was removed, I could log on locally, but I could not restart the NLA service. When I try to restart this service, the services.msc snap-in stops working and the server appears to partly "freeze" (example: I can change screen
resolution but the Start button does not respond).
While logged on locally and with NLA service still disabled, I reinstalled the virtual NIC through ESXi and the server re-established connectivity to the network.
At this point I can only log out, because if I restart it with the virtual NIC attached it goes back to hanging at the "Applying computer settings..." screen.
I'm not too worried about the virtual Server 2003 because we plan to move web services to Server 2008, but I still don't know why this is happening, what the relationship is to the WSUS updates that were applied (none of this happened before that), or how
to prevent this from happening in the future.
Thanks for your patience and advice.

What are the host network requirements for a 2012 R2 failover cluster using fiber channel?

I've seen comments on here regarding how the heartbeat signal isn't really required anymore - is that true? We started using Hyper-V in its infancy and have upgraded gleefully every step of the way. With 2012 R2, we also upgraded from 1gb iSCSI
to 8GB Fiber Channel. Currently, I have three NICs in use on each host. One for "No cluster communication" on it's own VLAN. Another for "Allow cluster network communication on this network" but NOT allowing clients, on
a different VLAN. And lastly the public network which allows cluster comms and clients on it (public VLAN).
Is it still necessary to have all three of these NICs in use? If the heartbeat isn't necessary any more, is there any reason to not have two public IPs and do away with the rest of the network? (two for fault tolerance) Does Live Migration
still use Ethernet if FC is available? I wasn't sure what all has changed with these requirements since Hyper-V first came out.
If it matters, we have 5 servers w/160GB RAM, 8 NICs, dual HBAs connected to redundant FC switches, going to two SANs. We're running around 30 VMs right now.
Can someone share their knowledge with me regarding the proper setup for my environment? Many Thanks!

Hi,
You can setup cluster with a single network but that leaves you with single point of failure on the Networking front, it is still recommended to have a heartbeat network.
Live migration would still happen though Ethernet, it has nothing to do with FC. Don't get confused, you had iSCSI for storage which used one of your VLAN and now you have FC for your storage.
Your hardware specs looks good. You can set up the following networks -
1. Public Network - Team two or more NICs (based on bandwidth aggregation)
2. Heartbeat Network - Don't use teamed Adaptor
3. Live Migration - Team two or more NICs (based on bandwidth aggregation)
Plan properly and draw guidelines to visualize and to remove single point of failure at all points.
Feel free to ask if you have some more queries.
Regards

What Gear do i need to enable WDM (DWDM) on a Dark Fiber?

We have Dark Fiber between 2 DCs and would like to enable WDM on it. What Cisco Optical Gear do i need for this? We would also link to enable Encryption on this link as well. TIA

You can do "simple" CWDM with the Cisco WDM series of CWDM Passive devices. Those can support 4 or 8 channels.
They depend on you "feeding" them signals from special transceiver models that modulate the light on a wavelength compliant with the ITU-50GHz channels listed in the DWDM SFP+ data sheet Leo mentioned and linked to.
The compatibility matrix tells you what Cisco gear is compatible with those transceivers. If you're using other 3rd party gear, they have equivalent support matrices. The bottom line is you need to match wavelengths to what the mux is expecting.
If you move up to the ONS 15454 line you have more flexibility - transponder cards etc that will transform standard SFP+ (1550 nm 10 Gbps signalling on fiber) to the ITU channels etc. You're talking serious money there though - hundreds of thousands of US$. Cisco will be happy to send a sales engineer over and build a nice detailed bill of materials if that's in your budget.

XSERV RAID FIBER CHANNEl

We have XSERV RAID MODEL A1009 with 4 Hard disk RAID 5.
Now I have installed CISCO 1000Base SX Module in 3 COM Switch & other same Module in XSERVER RAID. Now XSERVE RAID & switcted with Transeiver cable. Now I check RAID ADMIN TOOL FIber Channel Option the links shows down.
Let me know what is solution. Please also let me know how can I know that fiber link is up if any way.

Finisar makes a nice SFP to LC transceiver (available on the Apple Store for $99.95 for 2 Gbit and $119.95 for 4 Gbit) that you can use in the Xserve to allow it to accept LC optical cables. You'll need 2 of these, and then you can hook up LC optical cables.
I'll echo the other post -- be aware those ports are for fibre channel communication ONLY. You must hook it to a fibre channel card (HBA) in a host, or to a fibre switch (i.e. Cisco MDX 9000 series). You cannot hook up a network connection to those ports -- Xserve RAID provides data ONLY over fibre channel, it is not a NAS device. You must connect it to a host which can re-share the data over Ethernet, for example Xserve RAID with OS X Server which can reshare using AFP, SMB/CIFS, NFS, FTP, DAV, and more.

Setting Up Dual NIC Cards? Benefit?

Hello Everyone,
I know that the Mac Pro line comes with Dual NICs and I was wondering how do I set these up to be useful with my Cable Modem and Router? Can they be used to get more speed or are they used together in some other capacity.
I really appreciate anyones help and expertise.
Many Thanks,
Chris

The normal use of dual nic interfaces would be to run double instances of a given server on disparate IP numbers. Dual NIC's are generally employed in order to attach multiple IP addresses to a single machine.
Another potential use for dual NIC's is internet connection sharing, where your Mac Pro acts as a kind of router; again also this could be used for attaching one NIC to print services and the other NIC for LAN/WAN access.
OK, actually there are a whole bunch of good reasons for dual NIC cards, but 'doubling your bandwidth' is really not one of them. Believe me, unless you are on a direct fiber OC-10 20 foot from your ISP's NOC, then your existing single NIC has 1000 times the bandwidth of your incoming WAN connection.
It is likely possible to interleave dual NIC cards between two machines for bandwith purposes; but if that were going to be the canse, just identify one as "in" and the other as "out" (both machines would have to have dual NIC's to make this mean anything) but again, I honestly do not see a real world use for this...

Which NIC should I buy for Oracle Linux Server 6.4

Hi,
I am trying to install Oracle RAC 11g R2 onto my laptop PC - Lenovo T400s. I have installed Oracle Linux Server 6.4. The OOTB NIC was recognized by OS and eth0 is fine but I need one more NIC for RAC. RAC needs two NIC for public IP and private IP. Now I want to buy NIC for either USB or express card for the second NIC but I don't know which one to buy. Most of NICs that I find on the Internet is supported by Windows or Mac but I could not find any that says it is supported by Linux. Could someone tell me which one I should buy so I can download driver from the company website and compile from source hopefully..
Thanks,

hello,
you can build a rac on 2 laptos, sure
are some requirments , like shared storage
RAC will take, RAW device, block device, that can be SCSI, SAS, iSCSI, or lun by fiber channel, here in your setup, you wioll need to read about iscsi and use an storage
other option is use NFS, this will be more easy to implement.. if you have a 3rd machine you can setup it as NFS and mount the NFS int he 2 laptos
Good luck, is a doable task

10GE Twinax cables connecting to servers NIC which accept 10GE SFP+

Anyone has any real life experience of using the Cisco 10GE Twinax cables to connect this to servers with NIC cards that accept SFP+? I'm talking servers like HP and Dell which have 10GE NIC cards. For the switch, I would be using Nexus 5548UP. The SFP+ part number would be SFP-H10GB-ACU10M.
The SFP-10G-SR is too expensive and I'm looking at 10GE Twinax cables as an alternative but am quite concerned about the compatability.

Yes, the twinax cables are all we ever use to connect servers to Nexus 5ks. We have used them with both Qlogic and Emulex CNAs. If the server is more than 10m from the switch the 10G-SR and 50 micron fiber are required.
