David, Do you think Fiber Channel Directors, that have modules with Infiniband and iSCSI that pop in will be successfull? Where do you see the market for Directors going in 3 to 5 years. Do you think the port count on Directors will grow very large? Thanks for you input, Joe

Thanks David, for sharing the information from the show. What technology can be used with video that is better than FC and does not have the LIP problem you mentioned? or is there is way to improve FC so it doesn't have the LIP interruption problem? Thanks, Joe

David, <<With the advent of the internet, the shops buying most of the FC products today are 24 x 7. There is no longer such a thing as a maintenance window or downtime window.>> Yes, there is. I do have first hand knowledge. The last fortune 100 high tech companies I worked for are still doing it. The window is Sunday Morning 1:00 am est for a duration of 2 hours max. However, the network I supported was never down completely. Sections of them comes down for new software loading or making hardware changes (yes, including adding or removing disks/controllers) <<When you say that nobody should be doing configuration management in a normal operating environment, then you are incorrect (or perhaps dating yourself to the late 1990's)>> May be I should clarify myself. Normal operating environment is anytime outside of the window I mentioned above. <<Also just saying that the hardware doesn't fail often isn't relative. There is a lot of push from many vendors to go from the 4 9's to 5 9's for reliability and availability. (99.9999 to 99.99999 up time). They are paying big bucks for this as well.>> I said hardware that are used in mission critical applications do not fail often, i.e. availability of 99.9% like you said. The reason I brought this up was to argue on your point 'A 3-second LIP being unacceptable because of hardware failure and/or during adding/removing hardware from a FC loop.' The problem you mentioned was operation problem, not technological limitations of FC for applications such as streaming video. KJ Moy

David, <<So, according to your comment "Nobody should be doing configuration management during a normal operating environment", then you will potentially prevent any 24x7 environment such as visa, brokerage houses, the air traffic system, from operating. In the next 3-4 years, business will have 10X more data then they have today. You don't allow people to add any.>> I have what is probably a naive question, but in these 24 x 7 environments, how do people do archival backups? Most companies--many companies,anyway, banks, insurance companies, anyone doing on-line transactions, anyone needing to keep records for more than 6 months--still require them. Yeah, I have a vested interest in this, since I both maintain LT positions in and trade stock in tape and library companies. Thanks for your posts. The one on how many exabytes will be generated over the next years is incredible. And with all that storage, it is amazing to me we still have to wonder if the disk drive companies will make any money, or if they will just provide some nice salaries and options for a few of their employees.
