Sphere v. App v. App and a resource pool are not available as target options for upgrading a v. Center Server Appliance or Platform Services Controller appliance. When upgrading an appliance by using the v. Center Server Appliance installer graphical user interface GUI or the command line interface CLI, you cannot select v. App or a resource pool as the upgrade target. The v. Center Server Appliance installer interfaces do not enable the selection of v. App or resource pool as the target for upgrade. Workaround Complete the upgrade on the selected ESXi host or v. Center Server instance. When the upgrade finishes, move the newly deployed virtual machine manually as follows If you upgraded the appliance on an ESXi host that is part of a v. Center Server inventory or on a v. Center Server instance, log in to the v. Sphere Web Client of the v. Center Server instance and move the newly deployed virtual machine to the required v. App or resource pool. If you upgraded the appliance on a standalone ESXi host, first add the host to a v. Center Server inventory, then log in to the v. Sphere Web Client of the v.

Sphere 6. 5 allows only unique names across all Distributed Virtual Switches and Distributed Virtual Portgroups in the network folder. Earlier versions of v. Sphere allowed a Distributed Virtual Switch and a Distributed Virtual Portgroup to have the same name. If you attempt to upgrade from a version that allowed duplicate names, the upgrade will fail.

Infiniband at Home 1. Gb networking on the cheapWould you like to have over 7. MBsec throughput  between your PCs at home for under 1. Thats like a full CDs worth of data every second If you do, then read on. Since this article was originally written, Ive found the real world throughput of infiniband from a windows machine and an ubuntu machine gives me a max of 1. MBsec, just under twice my 1gbps ethernet 7. MB. sec. Thats with a raid array capable of 3. MBsec on the linux side, feeding a samba link to the windows machine at 9. CPU. So, it falls a lot short of the desired 7. MBsec that I thought may be possible. Its not possible with IP over Infininband. And i. SER isnt available on windows, so no SRP targets could be used, which uses RDMA. So a whole lotta research leading to block walls and 1. MBsec max. end editWith the increasing amout of data that I have to manage on my computers at home, I started looking into a faster way of moving data around the place. I started with a RAID array in my PC, which gives me read write speeds of 2. MBsec. Not being happy with that, I looked a creating a bigger external array, with more disks, for faster throughput. I happened to have a decent linux box sitting there doing very little. It had a relatively recent motherboard, and 8 SATA connectors. But no matter how fast I got the drives in that linux box to go, Id always be limited by the throughput of the 1. Gb ethernet network between the machines, so I researched several different ways of inter PC communication that might break the 1gbps barrier. The 1. GB ethernet was giving me about 7. MBsec throughput. The first I looked at was USB 3. While thats very good for external hard drives, there didnt seem to be a decent solution out there for allowing multiple drives to be added together to increase throughput. We are now starting to see raid boxes appear with USB3. To connect my existing linux box to my windows desktop, Id need a card with a USB 3. Gbps bandwidth of a USB 3. However, these do not seem to exist, so I moved onto the next option. Then I moved on to 1. G Ethernet 1. 0 gbits. One look at the prices here and I immediately ruled it out. Several hundred Euro for a single adapter. Fibre channel 2 8 gbits. Again the pricing was prohibitive, especially for the higher throughput cards. Even the 2. Gbps cards were expensive, and would not give me much of a boost over 1. Gbps ethernet. Then came Infiniband 1. I came across this while looking through the List of Device Bit Rates page on Wikipedia. I had heard of it as an interconnect in cluster environments and high end data centres. I also assumed that the price would be prohibitive. A 1. 0G adapter would theoretically give up to a Gigabyte per second throughput between the machines. However, I wasnt ruling it out until I had a look on e. Bay at a few prices. To my surprise, there was a whole host of adapters available ranging from several hundred dollars down to about fifty dollars. Gig adapter   Surely this couldnt be right. I looked again, and I spotted some dual port Mellanox MHEA2. XTC cards at 3. 5. Antropologia Cultural Y Social Pdf Software'>Antropologia Cultural Y Social Pdf Software. This worked out at about 2. Incredible, if I could get it to work. Id also read that it is possible to use a standard infiniband cable to directly connect two machines together without a switch, saving me about 7. If I wanted to bring another machine into the Infiniband fabric, though, Id have to bear that cost. For the moment, two machines directly connected was all I needed. With a bit more research, I found that drivers for the card were available for Windows 7 and Linux from Open. Fabrics. org, so I ordered 2 cards from the U. S. and a cable from Hong Kong. About 1. 0 days later the adapters arrived. I installed one adapter in the Windows 7 machine. Windows initially failed to find a driver, so I then went on the Open. Fabrics. org website and downloaded OFED2 3win. After installation I  had two new network connections available in windows the adapter was dual port, ready for me to connect to the other machine. Next I moved onto the Linux box. I wont even start with the hassle I had to install the card in my linux box. After days of research, driver installation, kernel re compilation, driver re compilation, etc. I eventually tried swapping the slot that I had the card plugged into. Low and below, the f cking thing worked. So, my mother board has two PCI Ex. Nfs Underground 2 Unlock All Hack. Who would have thought. All I had to do then was assign an IP address to it. EDIT heres a quick HOWTO on getting the fabric up on Ubuntu 1. About 1. 0 minutes should get it working http davidhunt. EDITWithout a cable it still had not arrived from Hong Kong, all I could do was sit there and wait until it arrived to test the setup. Would the machines be able to feed the cards fast enough to get a decent throughputOn some forums Id seen throughput tests of 7. MBsec. Would I get anywhere close to that with a 3. GHz dual core athlon to a 3. GHz i. 7 9. 50 A few days later, the cable arrived. I connected the cable into each machine, and could immediately send pings between the machines. Id previously assigned static IP addresses to the infiniband ports on each machine. I wasnt able to run netperf, as it didnt see the cards as something it could put traffic through. So I upgraded the firmware on the cards, which several forums said would improve throughput and compatibility. Iwas then able to run netperf, with the following results rootraid netperf H 1. TCP STREAM TEST from 0. AFINET to 1. 0. 4. AFINET demo. Recv Send Send. Socket Socket Message Elapsed. Size Size Size Time Throughput. Thats over 7 gigabitssec, or over 7. MBsec throughput between the two machinesSo, I now have an Infiniband Fabric working at home, with over 7 gigabit throughput between PCs. The stuff of high end datacentres in my back room. The main thing is that you dont need a switch, so a PC to PC 1. CAN be achieved for under 1. Heres the breakdown 2 x Mellanox MHEA2. XTC infiniband HCAs 3. Molex SFF 8. 47. Total 1. The next step is to set up a raid array with several drives and stripe them so they all work in parallel, and maybe build it in such a way if one or two drives fail, it will still be recoverable raid 56. More to come on that soon. References http hardforum. Follow climberhunt.
