No sorry, there is no plug-in for Synology to download patches (would be cool though - anyone?). However, I've been fiddling around with vSphere UMDS and wanted to have the patches downloaded to my Synology NAS box. And through the Synology webservices act as a patch store - AND IT WORKS :-).
Setup is quite easy, running a Windows 2008 machine. Now there are excellent tutorials and manuals available online to install UMDS, so I'm not going to repeat that.
Triggered by @esloofhis post on Freesco 0.4.3, I wanted to create such router into a VM, but for version 0.4.4. I also wanted to move it to a virtual disk so I could make an OVF and do multiple deploys. While trying to get this to work after a few hours, I finally found a really fast and reliable method to do it myself in like 10 minutes (and so can you after reading this manual).
What do you need?
- freesco, get it from here (download the ZIP) - ext2-0.4.4-lewis.pkg get it from here
Mr. @esloof did a nice tweet about this one and caught my attention. It's a very nice diagram in pdf format showing the memory management for vSphere 5. The thing I like best is the way it is set up: screenshot from esxtop, vSphere client and very clear mapping of virtual memory into physical memory. I'm printing it on A2 and stick it onto a wall and look at it from time to time. I suggest you do the same . Check it out here.
I received a link to this: VMware Technical Journal. Also @duncanyb also blogged about this one already. However, I want to stress how cool this document actually is!
Like: did you know VMware developed a tool called vmtar. A normal TAR is unaligned and vmtar makes sure the files inside the tar are aligned. Why do we care? Well, as the tar holding the core which makes ESXi tick are loaded into memory, some 'writable' files are copied to ramdisk. So the ramdisk and the tar are both in memory and somewhat the same. And there we have Transparent Page Sharing, optimizing the memory. If we didn't had vmtar, the tar files would be unaligned and TPS wasn't so effective - however, thanks to vmtar, TPS is more effective, saving more memory.
