3TB disks and GPT

With the 2011 range, we start providing 3TB disks
at OVH. It's just more than 1TB more than the 2TB disks
but there is a lot to change on the software side. Indeed,
MBR on the BIOS is limited to 2TB. So we go for
GPT (GUID Partition Table) which allows to have ...
9.4ZB instead of 2TB directly to the boot. Thus,
we can offer you the 3TB SATA discs
on the MG range. On the rest of the range is


If you opt for the SSD disks, you start
on the 120GB. You can also take the range
MAX SSD with 300GB. It becomes
interesting, 300GB for virtualization
data directly on the server because you
always have really incredible performance
with the Intel X25-M range.


You can also mix with SATA2 and
SSD drives. Why? To virtualize by hosting
data on the SATA2 and swap on the SSD.
In this case, we put 40GB drives.
This then also allows to do the opposite: boot
on the server and host all SSD
virtual machines on SATA2.

SAS 15000rpm/min

For those who do not trust the pro techs,
we offer 15000rpm/min SAS drives
of 300GB! Pro! And so if the SSD performance
makes you want it, but you do not
(yet) trust it, there is now SAS15k at
OVH on the EG and MG range.


On the SP, you only have a RAID-SOFT.
On the EG range, you can
take an optional hard RAID card.
On the MG range, OVH includes mega-RAID card
with a backup battery that powers
caches. Instead of writing on the
disks, the mega-RAID card
improves performance by writing on
a cache. After the data is written on
the disks. If there is ever a
power failure on the server (it never does
of course), the data stored in the cache is
not lost because the memory is powered by the backup
battery ... The mega-raid card improves
also flows to 6Gbps per disc instead
of 2Gbps.
