I do it by running an agent on the VM's, the host controls the order the guests are shut down based on battery percentage remaining.
eg. at 30 minutes left, shut down VM's 1 + 2, at 25 minutes shut down VM's 3+4 etc.
I am using LanSafe.
Has the website already been created ? was it database driven. It really should be build from the ground up to take full advantage of type ahead style searching.
If you were only interested in returning results for properties then you would only need to put that data into a database like MSSQL...
Not complicated at all, just use AJAX and PHP or some other language, initiate the ajax using javascript to trigger the update when someone has typed over a certain number of characters.. then use full text searching of a SQL database and return the results via the AJAX request. That's providing...
d link dsl2640b has issues with iOS devices.
Make sure you are on the latest firmware (check http://www.dlink.co.uk/ )
Switch off protected 54g mode, then reboot the router and try again.
Failing that, drop the security level down from WPA2 and see if it works after that, if it does you know...
Ordered at 00:30 on the 8th (took me 20 times to get the order through !!)
A couple nice 64gb + 4G's on their way to me.. bring on the Retina goodness :D
Not one of my linux servers runs a GUI.
But DK is right. If you are in a multi-role job (as I am) the number of languages to learn and try to remember is crazy, it's nice sometimes to have a GUI.
CLI isn't necessarily greater than GUI, but it is more powerful.
Sound isn't an issue because it will be going in a sound insulated half rack in my loft (along with everything else).
Software I use MythTV PVR Software (www.mythtv.org).
Yes, HD costs aren't the best at the moment.. that's why I'm holding back. If you are running win 2008 r2 you can just use...
Not going to watch the whole thing.. but within the first 30 seconds he is already wrong. RAID1 does give an increase in read performance.
RAID1 and RAID 5 offer the same level of redundancy, but very different performance characteristics. Keep watching videos on it until you grasp this.
The HP Micro looks pretty smart, and as long as you don't go over 5 spindles and don't need any significant CPU power (which I am guessing you lot don't) then they are perfect.
Unfortunately I am already at 9 spindles.. so that wouldn't be an option for me :(
Not when you are talking a significant amount of storage and server grade SSD's.
Generally speaking, the high voltage bits are not serviceable, hence they are not accessible when changing the batteries.
It's piss easy, just pull out the old batteries then replace and connect each battery in...
Had to replace the batteries in two of our 4U rack mount UPS's. One of them had actually started to leak before I began receiving alerts !! lol
Looked like these

Took about 12 per UPS. So 24 in total, but each manufacturer...
Run at least one of the PSU's on a UPS. Doesn't have to be anything special.. just enough to run it for 10-15 minutes. Set the UPS software to begin shutting down 5 minutes after a power cut. Most power cuts are seconds so your server would continue to run without ever shutting down.
No, its for redundancy.. you can pull either supply out with no effect on the system (other than generating alerts). Blade enclosures sometimes need three (or more) but at least one is reduntant should any of the others fail.
Just dont pull them both at the same time ;)
A proper setup should...
Yes, daily.. including purchasing, bare metal rebuilds, virtualization, consolidation blah blah etc.
I don't know HP kit (which I previously freely admitted.) The last time I did something similar I just build a new array and migrated the data across. The HP solution sounds painless.
Unless...
I promised myself I would stop contributing to this thread.. damn.
HP and Cisco are both good, my personal preference is Cisco but that's probably because I am CCNA.
24 port for all the difference in price... you will go through switch ports quicker than you think.
Don't bother with RAID...
:banghead:
lol
But raid 1 is 2 drives and will give you the same protection level.. better in fact as you don't need to deal with parity.
Only if you cannot achieve the capacity you are looking for should you go to RAID 5/6.
In laymens terms !
If disk 1 went down, you would loose
A2
B2
Cp
D1
We have parity data for A on 3, B on 2 and D on 0.
We don't need the parity data on the failed disk because non of the C data is missing and a new parity table can be rebuilt from the existing data on the remaining disks...
But what about RAID'd SSD's ? now that is the future :D
Was actually considering a RAID 10 SSD array for a SQL server but after performance monitoring the bottlenecks were the clients systems not the server. Besides, my SQL server pretty much holds it's entire database in RAM.
