You've read the headline - it's a 'significant' product, according to Bell Micro, the storage distie, which is making new 8Gb/s Fibre Channel HBAs available in Europe. Compared with the earlier 4Gb/s configurations, the new models offer more headroom to 'consolidate more resources, free up servers and reduce procurement and management costs." And that is good for virtualizing servers.
Here's the pitch from Fabian Hintzke, product manager for Emulex at Bell Micro: “Virtualising servers can really help firms get more from their resources, but with a 4Gb/s connection you soon run into problems. With these 8Gb/s systems you get the extra headroom that you need both now and for the future so not only do you benefit more from your bandwidth but you also have the flexibility to consolidate your server environment.”
