Comment on Adding physical drives to VMware ESXi by Enlightend

Yeah, I first stumbled on the same article you referenced, then went snooping around VMWare’s KB’s.

I can understand why they hide it a little bit, since on unsupported hardware, it can be disasterous. And their focus is on SAN/NAS storage anyway.

But it is working just fine for me.

470MB/s write and 530MB/s reads on a ZFS system without ZIL or L2ARC.

Performance almost nearing my previous Gentoo based Software Raid6 setup. And I haven’t tweaked anything in ZFS yet (have SSD’s incoming for L2ARC/ZIL)

And I also tried Nexento (now running clean latest OpenIndiana) and under VMWare w/Nexento performance was really bad, CPU load was always trough the roof, etc. With clean Nexento as the base OS, it wasn’t even half of what I’m getting with VMWare w/OpenIndiana+Napp-IT

Only problem I have now is that VMWare is bitching about an unsupported NFS version :@

Thanks for the tip, I’ll try this next time I add a new disk on the ESX. I found quite strange that this wasn’t available from the vSphere interface

You don’t really need to do all that to do raw device mappings.
Its actually built into the vSphere Client interface, but simply blocked for all local storage (although there’s plenty of hardware that works with it)

In esxi 5, goto:

Configuration > Software > Advanced Settings > RdmFilter and there you can disable the filter so LUN’s can be RDM’d directly from the “add disk” dialogue.
(not supported on all hardware, but it does work on all LSI IT flashable cards (SAS2008 and the likes)

I’m guessing that for 4.x it is the same procedure.

For ESX 3.5, you can use the procedure outlined in the following KB:

Hi,

I did not try any alternative, so I can’t recommand any other one. Remotemouse may be just good if you disable it when you don’t use it.

Many thanks for this post. Maybe this is a late comment but have you tried other apps? Any recommendations?

Comment on Reversing C++ programs with IDA pro and Hex-rays by Progman

The member variable length discussed is good for a start but not definitive.

Now I would say that you would need to correct this as classes can theoretically be variable length if the last member of the class is a variable length array for example as is commonly seen in C structs.

Thus to find the length of any class whether the child or parent in this case, you must look at all references to the constructor to find the maximal length which is probably fixed though could possibly be variable. Also you could do the same by looking at all the member functions of the class in question and its parents to analyze maximal length (if you understand the code you don’t have to guess).

Nope, sorry. Where I was, I couldn’t search anything on the net to ease my task. I’ll get back with more info if I find anything useful.

have u played with any plugins that claim to make understanding C++ easier and were any of them useful
