Thanks to each and everyone of you who took the time to download the vSphere 4.1 HA/DRS Deepdive kindle copy during our promo days. Over 6000 downloads in just 2 days is nothing short of amazing. Frank and I were talking about this promo opportunity a week ago for the 4.1 book and never anticipated on these kind of numbers. We expected a couple of hundred copies to be given away, maybe close to a 1000, but definitely not 6000+. Just some facts about this promo:
175+ retweets of my tweets
600+ tweets
30.000+ people reached
6000+ Kindle copies
We were shocked, we anticipated on a couple of hundred copies, maybe close to a 1000, but never did we anticipate on 6000 kindle copies being downloaded. Thanks to everyone who helped driving this. All the tweets / facebook and G+ mentions helped with this huge success.
Well, it’s been a very long time since I’ve done a “Mike’s Music” post. Mainly because one of my favorite music shows (Jool’s Holland) has been on a break – and then when the show came back I was bit uninspired… Anyway, the previous episode had a stonking return to form which is what inspired this post. It was one terrific performance after another – without the need for effusive personal testomonies or the need for “judges!”
I’ve got quite a lot of selections from youtube – so lets take this to a read more page…
Ren Harvieu was discovered on MySpace by manager Paul Harrison and producer/songwriter Jimmy Hogarth after uploading demo tracks, which Harrison and Hogarth listened to. She started recording an album but in May 2011, before it could be released, she broke her back in an accident where someone jumped over a hedge and landed on her. She spent two months in hospital recovering movement in her legs. On December 5, 2011, the BBC announced that she had been nominated for their BBC Sounds of 2012 poll. After releasing “Through the Night” (single) and “Open Up Your Arms”, her first album Through the Night was released on Kid Gloves Records on 14 May 2012.
Tom Jones is, of course a man who needs introduction. I think Tom has moved on from his days in Vegas and being inundated by women’s panties. He’s really maturing into a new phase. I think he might have the talents to be in the same league of Johnny Cash and his now legendary “American Recordings”. I first heard this song performed by white-noise band “The Jesus and Mary Chain” – and is originally a Leonard Cohen song (I’m currently listening to Cohen’s new album…). The Tower Song is followed by a number with Jools Holland on the piano – Travelling Shoes is a bit of gospel
The Punch Brothers are a progressive bluegrass band. The band consists of Chris Thile (mandolin), Gabe Witcher (fiddle/violin), Noam Pikelny (banjo), Chris Eldridge (guitar), and Paul Kowert (bass). Their style has been described as “bluegrass instrumentation and spontaneity in the strictures of modern classical”. What I like is they can just play there instruments really well!

Recently I received a question on twitter how the vSphere HA advanced option “das.isolationaddress” should be used. This setting is used when there is the desire or a requirement to specify an additional isolation address. The isolation address is used by a host which “believes” it is isolated. In other words, if a host isn’t receiving heartbeats anymore it pings the isolation address to validate if it still has network access or not. If it does still have network access (response from isolation address) then no action is taken, if the isolation address does not respond then the “isolation response” is triggered.
Out of the box the “default gateway” is used as an isolation address. In most cases it is recommended to specify at least one extra isolation address. This would be done as follows:
Right click your vSphere Cluster and select “Edit settings”
Go to the vSphere HA section and click “Advanced options”
Add “das.isolationaddress0″ under the option column
And add the “IP Address” of the device you want to use as an isolation address under the value column
Now if you want to specify another isolation address you should add “das.isolationaddress1″. In total 10 isolation addresses will be used. Keep in mind that all of these will be pinged in parallel! Many seem to be under the impression that this happens sequential, but that is not the case!
Now if for whatever reason the default gateway should not be used you could disable this by adding the “das.usedefaultisolationaddress” to “false”. A usecase for this would be when the default gateway is a “non-pingable” device, in most scenarios it is not needed though to use “das.usedefaultisolationaddress”.
