I have questions about Broadcom adapters which are in my servers. Speaking directly with Broadcom has proven fruitless. They deny that they have anyone I can speak to about these questions, or that they actually do any manufacturing.
After a lot of time searching through nooks and crannies on the web, I haven't really come up with solid information. So I'm hoping that there are enough people out there with experience who can give me clarity.
I have (admittedly ancient) Dell 1950 III servers, with BCM5708 embedded NICs and BCM5709 cards. I am running ESXi 5.5u2
I have the following questions:
1) How can I find out what level of firmware each of the NICs have ? While we're at it, is there a GUI utility like HWINFO (Windows land) which presents all of the ugly details of the hardware/firmware in an ESXi host ?
2) I have seen a number of 'firmware updates' in various places on the web relating to these devices, from different vendors, such as Dell and IBM. I came across a posting on the web indicating that these devices should be at 6.2.14 or 6.2.1b
I know that sometimes there actually is customization to the point where firmware updates can 'brick' a device. What version can/should my NICs be at ?
3) Dell offers firmware upgrades as Windows executables, which will probably not work for ESXi. How do I go about getting the firmware updated ?
4) Only two of the devices show as iSCSI adapters under storage adapters. I gathered (hopefully correctly) that this has to do with the firmware on the NICs. Will the update cause them all to show as iSCSI adapters ? Is there some other way to accomplish that, such as changing configurations directly on the adapters ? What utility do I use to accomplish that ?
5) I also came across a posting which indicated that with the latest drivers, these cards will do both TOE and jumbo frames. I am under the impression (again, hopefully correctly) that TOE is implemented in hard/firmware, while jumbo is set up in software. Is there a good reason to/not to use these together ?
6) I came across a driver update for Broadcom NICs (1566459) on the VMware website and installed it on ESXi 5.5, but that didn't make any change in the way they appear within the ESXi console. Should it ?
7) I have come across postings which indicate that the ESXi software iSCSI adapter should be avoided if possible. I saw that there were dramatically longer boot times for a server when that feature is used. A lot of the above has to do with my reluctance to use the software adapter if I can avoid it. Is it possible to do that, or will ESXi insist on my using it ?
Responses are appreciated. Good responses are especially appreciated (how do you spell beer ?)
Thanks to all.
