During over the past several months, store much marketing gags about Ethernet. On one hand, seem each the intersection of Ethernet and the intersection of switchboard and manufacturer increase such a word at ppt of products propaganda their: ” fiber channel and iSCSI ” ,On the other hand, various standards, for example FCoE, CEE merge and strengthen Ethernet , DCE Ethernet of data centre Or DCB the data centre bridges When vying each other. Standard all these, for let Ethernet like fiber channel, thus create one unitary the intersection of data centre and transmission network.
In most bordering on ESG exhibition held in Bostonning, I have asked such a question of experts of a houseful of networks: Do you think your enterprises will regard Ethernet as the standard transmission net which store the network? And I especially point out saying here, the memory network meant SAN was not NAS yet while asking this question. The results by a wide margin to this question of experts are as follows:
42% are answered ” ” ,But there is no particular arrangement time table.
32% are answered ” ” ,Say they are doing so.
5% are answered ” ” ,Will dispose in future 12 to 24 months.
21% are answered ” Deny ” ,Say they continue, let network and store network, run alone.
My idea is:
1. Two years ago, I had told my memory colleagues, once the every port price of 10GbE was lower than 500 dollars, and should consider adopting FCoE when the 10GbE net card mixes as prize of the server of Intel. Nowadays, the situation has been already roughly like this. The market is increasing to the demand for 10GbE, 10GbE server network card already become the major disposition, and the decline of every port price of switchboard is driving more FCoE demands.
2. Cisco claims, on its Nexus 5000 overhead type switchboard, FCoE additional speed already accounted for 33%. Obviously, Cisco to come, push away his FCoE with UCS and vBlock.
3. Today, the implementation of FCoE is limited to from the server network card to the overhead formula TOR The the switchboard one ” Jump ” . This causes laughing at to FCoE of some people in the industry, think it is just a kind of access network technology. But such a view obviously comes from manufacturer and technologist, the users do not look in this way. IT expert think, only need to the cable and insert the switchboard and pay canonicalization, can cancel on HBA Host bus adapter,if you can’t offer, input between server and storage equipment /output processing . ” jump ” Limitation,IEEE it last limitation for to plan hard.
4. FCoE has totally changed and stored the trade. Today, store the manufacturer and sell storage system, HBA and switchboard, and maintain the strict control to the whole product chain. If a certain storage equipment is unable to support, it may be invalid to dispose, will influence your maintenance agreement at least. In the near future, storing the manufacturer will have to give up the control of the infrastructure, and use to guarantee the perfect operation of the system on the basis of the canonial Ethernet switchboard’s apparatus. Hewlett-Packard will lead this change most probably, because it has already produced the server, also produce network equipment and storage system. Whom one market drive, may promote Hewlett-Packard and store the share of the market on the basis of canonial the intersection of FCoE and solution perhaps.
Certainly, I know too FC market of hundreds of millions of dollars will not change overnight today, but I dare to bet this kind of change will happen soon. The answer of my above-mentioned problem shows, this kind of change has already taken place, and the strength of market will only accelerate the arrival of this trend. wave wave is compiled
