SAN 2.0 - Available Today
At the conference last week, I had to spend a lot of time convincing a single customer that NetApp was producing devices running on a SAN. The image of NetApp as a company that is primarily a leader in the NAS market is very strong, and not everyone knows that the first SAN devices were released by NetApp in 2002 as part of the Unified Storage idea.
Now, when hardware manufacturers (primarily Cisco) are promoting the idea of FCoE as the next-generation SAN (SAN 2.0, so to speak), and are turning to the idea of using a single wire to combine block and file traffic, NetApp is still the first and only end -to-end FCoE solution. In short, FCoE adapters can be installed into existing storage systems. Others don't have native support for FCoE. The interestingness of such adapters is precisely in combining the types of traffic - it is possible to transfer block data (FCoE, iSCSI - available now), and file data (CIFS, NFS - will be available later).
UPD. To make it clear what kind of hardware we are talking about:
')
1) When they say FCoE, two topologies can be implied:
a. Mixed - servers are connected via FCoE, DSS - via FC, as usual, the switch performs the conversion. In this mode, most storage systems of other vendors support their work.
b. Native (end-to-end FCoE) - the storage system is connected immediately via FCoE - only NetApp can do this (as of the moment of publication)
2) The work on FCoE is supported by all currently sold equipment that has expansion slots - FAS2050, FAS31x0, FAS60x0 - www.netwell.ru/production/netapp_product.php . The previous generation models are also supported - FAS3040 and FAS3070.
Expansion cards are called Unified Target Adapter - available in two versions: optics (LC connectors) (p / n X1139A) and copper (Twinax) (1,3,5 meters) (p / n X1140A).
Through these cards, FCoE, iSCSI, CIFS and NFS can be given at the same time - all other storage vendors need to separate block and file access to different ports switches, negating the benefits of FCoE for consolidation
To the question - how will they all share the channel - in January 2010, Demartek conducted performance testing with simultaneous operation of FCoE and iSCSI through UTA. Report here - www.demartek.com/Reports_Free/Demartek_NetApp_Unified_Networking_Evaluation_2010-01.pdf
3) Switches - Cisco (Nexus 5010 and 5020) and Brocade (8000 - a separate switch, or module FCOE10-24 for directors DCX / DCX-4S
4) CNA for servers - Qlogic QLE8152, Brocade BR1020, Emulex LP21000. All CNA is in two versions - optics and copper (Twinax).
Who cares about FCoE? Look at Cisco UCS solutions, where servers are sold bundled with Nexus - FCoE is the only option there, and in order to get support for native FC in Nexus, you need to buy additional expansion modules.
Well, in 2011, taking into account the close ratification of standards related to the Ethernet part, all network vendors will release something and prices will start to fall.
