Hi Urban,
I'm interesting in your hardware configuration, in percent how much is
the I/O on indexes volume and how in maildata volume?
Without index on SSD you will be able to run 28k users on RAID10
(SATA/SAS) only?
I'm evaluating if store indexes, on my configuration, on SSD for
improving performance.
Thanks

Hi Rajesh,
our setup looks as follows:
- we are running linux-vserver as virtualization technology
- we have 2 dedicated IMAP/POP3 Proxies in front of 8 dovecot containers.
- totally about 2900 concurrent imap sessions on each imap proxy and about 180
concurrent pop3 sessions
- all dovecot containers are running on the same hardware (no problems until
today):
DELL PER720 with 2x 200GB RAID 1 SSD's for dovecot indexes, 8x 4TB RAID
10 for maildata, 2x300GB RAID1 for OS
64GB RAM, 2x CPU E5-2640 0 @ 2.50GHz
