Real men don't make backups
I needed to plug into UPS a device with standard Europlug 220V. However, my APC UPS has only eight C13 sockets.
What I did? I bought a standard multi socket extension cord/lead with 3 outlets (variant compatible with Type C and F Electrical Outlets). Then, I cut off the standard plug, and swapped it with rewirable DIY C14 plug.
BTW, there is at least one manufacturer that is producing UPSes with Europlug. It is Orvaldi. See the last photo.
Yesterday our sites hosted on HostGator was down for a couple of hours (5h 34m). Now everything is up, and is functioning normally.
To our big surprise, the new Intel Raid controller on the Motherboard Intel DX79TO (ver. AAG28805-401) with Intel X79 Express Chipset shows awesome read performance.
The raid model is Intel Rapid Storage Technology enterprise 3.0 (Intel Rapid Storage enterprise – SATA Option ROM – 3.0.1.1370, 2003-2011), which in Microsoft Windows is reported as “Intel C600 Series Chipset SATA RAID Controller”.
Usually, with old Intel RAID models (till ICH10R?), RAID 1 mirror reads only from the one drive at the same time. The last time we tested this, was November 2010 with Intel RAID controller ICH10R.
Now, our test shows, that the new Intel RAID 1 reads from the both mirror drives simultaneously. Writing speed stays the same, however reading speed is twice as fast. Basically, you get read performance the same as from RAID 0 stripe.
Our test setup.
For more details, see the screenshots at the end of this post.
Test results.
Conclusion.
It is possible to get a stunning HDD/SSD read performance with consumer grade hardware. Also, note that in this setup the SSD reading speeds exceeds 1000 MB/s or 1 GB/s. The whole setup costs about $1500.
