- EMC Community Network – ECN: Vblock Reference Architecture –
Here is the newest Vblock Reference Architecture. solution using VMware vSphere on a Cisco UCS connected to an EMC CLARiiON CX4, or V-Max. Take a look. It's a great collaborative efforts of EMC, VMware and Cisco.
I have a post brewing about vBlock and Acadia but here is the official specs on vBlock design. Remember: If you don't like them, you can always build your own.
- Oracle drops top architect into MySQL skeptic zone • The Register –
If Oracle corporate hoped Screven's message would draw applause based on some collective relief it was wrong: just one person in the hushed room clapped – furiously – and this was possibly one of Oracle's employees spotted at the show trying to cheerlead a round of unspontaneous applause.
Who could believe Oracle would support open-source without attempting to "close" it in some way. Oracle is well known for raping customers wallets, and ramping up charges in every aspect of its business. A volte-face to offer open source MySQL doesn't ring true.
- Slashdot Hardware Story | Lessons In Hardware / OS Troubleshooting –
We like to imagine that every Microsoft OS installation will work just as well as the company promises. When things don't work out, identifying and remedying the case of failure can be time-consuming and frustrating. This lesson in how to determine why Windows 7 didn't install may help you troubleshoot a problem of your own, and save you from a Lost Weekend. Maybe you'll find this account useful all on its own. But the real key here is that the author is Ed Tittel — who's written over 100 books. If this hardware geek spends days solving a CPU-meets-Windows 7 problem, what chance do mere mortals have?"
So true, why do we put up with the poor quality of Microsoft software ?
- Cisco IOS hints and tricks: Did you notice 15.1T is released? – Ivan has a good review of the IOS 15.1T. especially this bit:
Oh, BTW, if you wanted to save money and test this release on your Dynamips-enabled 7200 clone, you’re out of luck; 15.1T runs only ISR and newer hardware.
Dynamips is fading away.
- StorageRap: Calculating the output of wide striping arrays –
Wide striping is a method of spreading data over a large number of disk drives in a storage array in order to achieve a desired performance goal. The term wide striping has been used sometimes to refer to sets of disks with 16 to 32 members, or more. It seems strange that somebody would classify a 32 member disk set as having wide striping, when you compare that to a disk set with 320 members, but that's how definitions in the storage industry tend to be broadly interpreted – especially by vendors :).
If you don't know what wide striping is then this is best description I've ever seen. Marc Farley is one of the best bloggers in this space and gets great information that even I can understand. Unlike many storage blog posts, I didn't fall asleep before the end.
- Tories may scrap IR35 tax rules for contractors • The Register –
It prompted an outcry from self-employed IT workers, who mounted High Court challenges and claimed IR35 would cripple the UK IT industry.
Not exactly, but life would be much improved if their was no IR35 obligations.
- Out-of-Band network « Routing Bits –
The options available if the 3G router only receives a dynamic public IP:
Dynamic DNS via an online DNS company like www.dyndns.org would be used.
Using an EEM script, the Cellular interface IP can be mailed to a public mail box every so often. (Don’t use your company email address)
Alternatively a more secure solution would be tweet the Cellular interface IP to a locked private twitter account. (This is my recommended method, as it adds a third layer of security). Refer to a earlier post I did on this here.
Smashing bit of joined up thinking.
