many thanks Marks. I referred to the fact that the Sun microsystems patch IIIRC solved most of iscsi access .

EDIT: the monthly transfer I can expect is around 5 TB right? My app will do 90 % downloads and could restrict it to France only ( which would be very cheap for OVH). If I order through a French reseller, may I get more traffic than 5 TB?

Thanks again

what do you mean by:
why does OVH still charge for access to disk if this is a solved issue
If you mean the new RPS Standard/Premium/Business, the difference is in the guraranteed speed. If there is no constrain on the network, they all perform at the minimum speed contracted. But if there is not pressure on the network, they can perform much better.

Standard: minimum 1MB/s
Premium: minimum 4MB/s
Business: minimum 10MB/s

i've run some tests to show it here and these are the resulting speeds (this may vary quite a lot, but at least it's an idea of the performance):

Business:
dd if=/dev/zero of=TEST.zero bs=100M count=1
1+0 records in
1+0 records out
104857600 bytes (105 MB) copied, 4.18382 s, 25.1 MB/s

Premium:
r11358:~# dd if=/dev/zero of=TEST.zero bs=100M count=1
1+0 records in
1+0 records out
104857600 bytes (105 MB) copied, 5.36255 s, 19.6 MB/s

Standard:
root@rescue:/# dd if=/dev/uba of=TEST.zero bs=100M count=1
1+0 records in
1+0 records out
104857600 bytes (105 MB) copied, 6.67253 s, 15.7 MB/s

As I said, it's just an idea of the performance at a given time. I've done several tests and these results are a bit the average.

Can someone please leave any feedback to know if the "new" RPS īs are any better? If so, why does OVH still charge for access to disk if this is a solved issue, thanks

has someone tried the patched RPS?

are they any good compared to the 1MB/sec ones?

Thanks
