Computer Server Rack Facts, Questions and Answers..
Yesterday I was reading some friends’ RSS feed when I found this nice resource for us little geek around on the topic of berver’s rack mounting and management. If you too are into this world don’t miss the chance to bookmark/follow these guys!
Apple's Magic Mouse
It’s amazig how 10g of difference in weight can make you feel entirely different the use of an Apple’s Magic Mouse with the original battery kit inside and one with plain rechargable Duracell one.
{I’ve measured 105g vs 116g with my food balance}
At the middle of last september I gave myself a little present, getting the 2nd Apple desktop machine in these last 5 years of “mac-addiction”, a mid.2011 entry-level MacMini [for the onlookers out there the first desktop was a PowerMac G4 "Quicksilver"].
The specs aren’t impressive but at home I needed a machine that could be leaved always-on, ready to serve, print, download camera’s photos and be – as soon as I’ll have a little time – a photo and music media server to my LCD tv in the drawing-room [probably with PS3MediaServer].
Those are the first results of NovaBench‘s run on the MacMini with it’s default hardware equipment: 578 points.
I had then the chance to upgrade my MacBook Pro RAM from 4GB to 8GB … so, even if RAM’s speed was lower (1067 MHz instead of 1333 MHz) I decided to try to put them in the MacMini … 10 minutes and 3 NovaBench’s run later these were the results: 581 points.
Finally this week, after a Riccardo‘s tweet on getting value RAM via Crucial’s shop I’ve ordered mine, and moments ago I’ve installed it and this is the 1st result after the boot: 618 points.
40 points of difference (with no special attention to tuning anything) for 32.99€ (taxes excluded, shipping included). Not bad … or not ???
Lately at work I had to struggle a bit with the recovery of a personal workstation. Once very powerful nowadays with the dead of some of it’s disk, the subsequent loss of any RAID functionality (investing in IDE drives doesn’t make sense), and it’s “low” 1.5GB of RAM it’s just enough for some basic uses.
Unfortunately there has been an issue with the drive that resulted in (a near) complete data loss.
It was time to reinstall it, but default procedures failed. Ubuntu, Fedora, CentOS … ALL of them gave me an issue. Then I remembered how Promise RAID chipset on main motherboard had bad comments at the time, many regarding the poor implementation of RAID drivers.
So I’ve entered the BIOS of it’s motherboard (an Asus P4B533-E model) and disabled all internal support to raid.
Then I’ve booted my Fedora 15 DVD and at the prompt I gave the
linux nodmraid
command, disable so any fake RAID in the motherboard or RAID controller BIOS so that it acts as a normal controller.
BAM! It worked!
