Some follow up PCoIP Questions.
On Wednesday (12/15/2010) I had the pleasure of speaking to a group of people in Troy Michigan (my slide deck is at the bottom). This was a discussion around “Why EMC for VMware View”. We discussed all the benefits of a secure virtual desktop as well as the scalability and flexibility EMC’s storage offers them. What was really cool is a majority of them were either wrapping up their View POC or were in full production. We had a few questions that came up that I wanted to capture here, and post the answers for others to benefit from.
1) What is PCoIP
If you go to Wikipedia, it defines it as: PC-over-IP (PCoIP) is a proprietary protocol for remote workstation and desktop solution, designed and developed by Teradici. PCoIP enables remote access to workstations and servers, normally hosted in a machine room or data center, from a thin client (advertised as a ‘zero client‘), which can be just an LCD monitor with a PCoIP client processor integrated. The PCoIP protocol transmits only the changing pixels across a standard IP network to stateless PCoIP technology enabled devices
The Net-Net of this is PCoIP is a new protocol developed by Teradici that only sends the changing pixels across the network. This has the potential to significantly reduce the amount of bandwidth needed. YMMV.
2) What sort of advice can you give us on PCoIP bandwidth sizing and hints/tips etc.
First and foremost, your mileage WILL vary as well as the responses you will get when asking these questions. These are just my opinions!!
PCoIP bandwidth sizing is an interesting endeavor!! First and foremost, you should understand that PCoIP is a UDP protocol. What this means is the use of WAN accelerators is not really going to help. I can also tell you that PCoIP will eat up every bit of bandwidth it can get so network QoS is going to be really important. There are a ton of hints and tricks to optimizing PCoIP written by Andre Leibovici of VMware on his blog so make sure you check it out. Also, VMware has a great information guide around PCoIP Display Protocol: Information and Scenario Based Network Sizing Guide you should read.
3) Hypothetically speaking, how many PCoIP sessions could I expect to get out of a T-1 line?
Again, you mileage will very but I’ve spoken to a few view experts (Chris Reed of INX, Aaron Patten of VCE and Ed Saiptech fellow vSpecialist) and each felt that 5 to 10 live desktops per T-1 is a good rule of thumb. Now, if all they are doing is office/outlook work then you can probably double or triple that number, BUT your mileage will vary!! Everyone agreed that you will want to work with a network savvy VMware View consultant.
So, hopefully this answered a couple of the questions that were thrown out during the session. This was my first trip to Detroit, and boy did I pick a cold day to go, but the hospitality was fantastic. Special thanks to Dennis Callaghan, his rockstar TC Chris Pawlowski as well as all the other EMC’ers I met. Thanks for making me feel welcomed!!
PS – here is the preso I used yesterday. Let me know if you have any further questions !!
