Algunos Beneficios del Cloud Computing Las infraestructuras de Cloud Computing proporcionan mayor capacidad de adaptación, recuperación de desastres y reducción al mínimo de los tiempos de inactividad. No necesita instalar ningún tipo de hardware o software: una infraestructura 100% de Cloud Computing tiene como atractivo su simplicidad… y el hecho de que requiera mucha menor inversión para empezar a trabajar. Se redirigen los costos de CAPEX y problemas de capacidad al cloud provider. Los cloud providers están interesados en tener lo más que puedan de la infraestructura de storage y procesamiento de sus clientes. Business and Technology Working as One

- DOM= digital optical monitoring Portulla (2248) and Woodside (2232) ASICs support both local classification and policiers. No commited features on the roadmap to leverage the policiers currently. QoS policies on the system are function of both the line card (N2K) and the parent switch (N5K/N7K) and the system QOS design will leverage overall capabilities of both. Transcript : So if you look at the lay of the land at the moment with the 2148T, we obviously have the 2148T shipping today. And there's a couple of things that I'll probably want to point out. Certainly I think you're probably all familiar with the architecture and the restrictions of the platform today. But some of the things I probably want to call out include support only for 1Gig, so essentially 1000Base-T. Essentially also there's no local classification capabilities, no FCoE support, as well as no local port channel capabilities today. However it is obviously shipping and supported today. And certainly if you do have any requirements to propose an architecture in any new data center build outs that require 1Gig connectivity, Certainly I would encourage you to actively keep selling the 2148T. It has been very very popular and has been very very successful for the Nexus 5000 series platform. So also with the upcoming new series platforms we're going to be introducing them in essentially two phases. One is what we call the SFP sort of pluggable options and the second one would be a 10Base-T type of option. So first and foremost, probably around Q2 timeframe with Calendar Year 2010 we're going to be introducing a 2248 what we call TP. I'll talk about a nomenclature in a moment, but we're also going to at the same time be introducing the 2232PP as well. So both SFP pluggable-type of options for uplinks and in the case of the 2232 SFP options for downlinks as well. Both of them will still be one rack unit in form factor. The 2248 will add the connectivity capabilities of 100Meg in addition to 1Gig and the 2232 will essentially have both 1Gig and 10Gig connectivity options as well. Likewise as I mentioned earlier, there is some local classification capabilities both for QoS and ACLs, so we're basically going to be factoring both of them in, although maybe not at FCS, most likely in a subsequent software upgrade. But bear in mind that the hardware is capable of handling that for a software upgrade. Other things include local port channel capabilities. Once again, we do support VPC across Nexus 2148T ports today, but the current generation of 2000s don't have any local port channel intelligence. As a result of that you can't channel between ports locally on the same Nexus 2000. So with the new Nexus 2000s we will offer that capability, so both on the 2248Ts as well as the 2232s we'll offer local port channels as well as VPCs. From a timeframe perspective the new Nexus 2000s will be introduced starting from Q2 of 2010 for the pluggable options, and moving to second half of 2010 for the 10GBase-T options as well. From the Nexus 7000, just reading from this slide, certainly the first FCS will be available with the 2148T from the Cairo software release, which will be roughly about the Q2 timeframe, and then following with the 2248T from Q3 and the 2232 from Q4 and onwards. Author’s Original Notes:
- Transcript: Now let's look at an actual simplified deployment model for the consolidated fabric, and in this case using Fibre Channel over Ethernet. On the left we show an simplified model of a traditional data center infrastructure today. In the servers at the bottom of the left hand side, you see a multitude of network interface modules inside the servers. Again, typically between six and eight adapters per physical server. And in the access layer, you have many different types of switch devices. You have your traditional LAN switches for Ethernet, your SAN switches for your storage traffic, or Fibre Channel traffic, and you have redundant links, naturally, in order to maximize uptime, in both the Fibre Channel space, and also in the LAN space. Now this is simplified because traditionally in data centers you also have many different cluster environments that are often autonomous, separate networks. So if you look at the network on the right, we've implemented I/O consolidation through the use of a unified fabric. And in this case, because it's Fibre Channel, also the use of Fibre Channel over Ethernet, or FCoE. So we go down from four switches on the left, to two switches on the right, and two switches for redundancy purposes. And we go down from about six to eight adapters on the left, to just two converged network adapters per server in the picture on the right. And if those were six adapters on the left, this would correlate to a 66% reduction in the number of cables inside this simplified network architecture. In this environment we're showing that the Nexus 5000s take in traditional Ethernet traffic, 10GE traffic, coming from the converged network adapters out of the servers, as well as Fibre Channel over Ethernet, again, also coming from the converged network adapters. And then the Nexus 5000s actually convert the FCoE traffic back to Fibre Channel for connectivity back to the SAN A and SAN B target systems. Author’s Original Notes: Today: Parallel LAN/SAN Infrastructure Inefficient use of Network Infrastructure 5+ connections per server – higher adapter and cabling costs Adds downstream port costs; cap-ex and op-ex Each connection adds additional points of failure in the fabric Longer lead time for server provisioning Multiple fault domains – complex diagnostics Management complexity – firmware, driver-patching, versioning
- Transcript : What is FCoE? It's the mapping of FC frames. It's basically the letter in the envelope; the letter is now fiber channel, the envelope is Ethernet. Stick one inside the other, when it gets to the edge of the network where fiber channel is required we just rip off the Ethernet envelope and pass it along as fiber channel normally passes traffic along. Now both block I/O and Ethernet are running over a common infrastructure. There's a ton of savings there. Reduction in power and cooling, reduction of cabling infrastructure. Reduction of overall management of the infrastructure; you have one big unified fabric to manage as opposed to managing separate islands. Fewer adaptors are needed and there's no Gateway required it's a full stateless implementation. This is why it's so attractive to our customers. We don't have to worry about performance penalties for doing fiber channel over Ethernet like in iSCSI and we will do both. Actually DCB will even benefit iSCSI networks. Why, because it's lossless. So we're still heading down both paths, it's just a customer choice. Cisco does not hold technology religion, we never did, never will.
