Jul 19, 2013 - HP has released a significant firmware update to its Virtual Connect line of HP. As a separate standalone update tool (bootable ISO file) or as a HP SUM component. HP Virtual Connect 4.01 can be downloaded from here. Re:Invent re:Invent Scale Serverless Simulator Storage Tech Field Day. HP Prime Virtual Calculator Emulator (32-bit) Beta Description: Beta version of the emulator (technically a simulator, since it is a native PC program) of the HP Prime Graphing Calculator for Windows. ![]() ![]() And I have spent a lot of time recently scratching our heads over how and where fibre channel SAN connections go in a c7000 blade chassis. If you don’t know, a FC-VC module looks like this, and you install them in redundant pairs in adjacent interconnect bays at the rear of the chassis. You then patch each of the FC Ports into a FC switch. The supported configuration is one FC-VC Module to 1 FC switch (below) Connecting one VC module to more than one FC switch is unsupported (below) So, in essence you treat each VC module as terminating all HBA Port 1’s and the other FC-VC module as terminating all HBA Port 2’s. The setup we had:. A number of BL460c blades with dual-port Qlogic Mezzanine card HBAs. Hp Virtual Connect ModuleHP c7000 Blade chassis with 2 x FC-VC modules plugged into interconnect bay 3 & 4 (shown below) The important point to note is that whilst you have 4 uplinks on each FC-VC module that does not mean you have 2 x 16Gb/s connection “pool or trunk” that you just connect into. Put differently if you unplug one, the overall bandwidth does not drop to 12Gb/s etc. It will disconnect a single HBA port on a number of servers and force them to failover to the other path and FC-VC module. It does not do any dynamic load balancing or anything like that – it is literally a physical port concentrator which is why it needs NPIV to pass through the WWN’s from the physical blade HBAs. There is a concept of over-subscription, in the Virtual Connect GUI that’s managed by setting the number of uplink ports used. Hp Network Simulator DownloadMost people will probably choose 4 uplink ports per VC module, this is 4:1 oversubscription, meaning each FC-VC port (and there are 4 per module) has 4 individual HBA ports connected to it, if you reduce the numeber of uplinks you increase the oversubscription (2 uplinks = 8:1 oversubscription, 1 uplink = 16:1 oversubscription) Which FC-VC Port does my blade’s HBA map to? The front bay you insert your blade into determines which individual 4Gb/s port it maps to and shares with other blades) on the FC-VC module, its not just a virtual “pool” of connections, this is important when you plan your deployment as it can affect the way failover works. The following table is what we found from experimentation and a quick glance at the “HP Virtual Connect Cookbook” (more on this later) FC-VC Port Maps to HBA in Blade Chassis Bay, and these ports are also shared. Sorry for delay in approving your comment, it was stuck in my spam queue 😦 in a nutshell; Virtual Connect = abstraction, configure your SAN zoning and LUN masking once by using the virtual WWN of the VC modules; if you swap out the blade and/or HBA mezzanine card. Integrated blade switches = more switches in your DC, more spanning tree and more management and you need to manage a core, distribution and edge switch topology. If VM’s do a lot of talking to each-other within the same chassis, then maybe switches rather than VC are a better approach – keep all traffic within the chassis rather than trunking out to external switches and back in again – VC modules do have private networks but they are not L3 routeable to the outside world IIRC VC always needs external switches, so extra cost but easy swap out and configure once. VC does need external switching. Spm never change album download. What has changed, though, is the way SPM emphasizes the vocal hooks -- they anchor each of his songs, with Ayana handling most of the hooks. SPM hasn't changed much as either a producer or a rapper -- his trademark snail-paced, low-toned idiom and his mid-tempo, sparse tracks are highly evident.
