Brocade’s BR-MLX-10Gx24-DM line card for the MLXe Chassis isn’t as I expected.
Brocade recently released a line card that has 24 port of 10Gig (BR-MLX-10Gx24-DM) in a half slot form factor for the MLXe chassis. To run this card, the Ironware version needs to be at 5.4 or higher. While reading the upgrade guide I found this note on Page 73 of the upgrade guide.
For maximum performance you must operate your BR-MLX-10Gx24-DM interface module with high
speed switch fabric modules in turbo mode.
How to enable Turbo Mode? I went to the configuration guide to find that and this is what I found.
The module can support up to 200Gbps when the system fabric mode is in Turbo mode (i.e.,
the system contains only Gen 2 and Gen 3 modules such as the MLX 8x10G, 100G or 24x10G
- The module can support up to 12 10G wire-speed ports when the system fabric mode is in
Normal mode (i.e., the system also contains any Gen 1 modules such as the MLX 1G or
Below is the link to find out if your line cards are Gen1, Gen2, Or Gen3. Depending on the other line cards in your chassis, you may get 18 or 12 line rate gig ports with this card.
Brocade is not the only vendor that is doing this with their high density 10G blades. Cisco has a blade on the market that needs to be in it’s own VDC on the Nexus 7000 platform for it to work.
Always ask lots of questions and read about how the hardware is going to perform so you have the correct expectation when you get the cards.
Has anybody purchased this card? If so, how is it working for you?
