Need Urgent Support intel Raid adapter dedected

[amravit]

hello
i have cirtical issue all my servers are supermicro with very nice specs the smallest one is dual quad core prossor x5470 my main issue they all come with intel / adaptec bulit in raid adapter none of them have been dedected by proxmox installtion
i have very bad issue with I/O we run lotus /domino production mail server
which handel around 300 mail account but this server is highly used my current x5570 dual prossor 16 core with ht and using normal sata drivers
is dieing because of i/o wait which reach around 30 to 50 %
i have another server with scsi 10 k drivers but as i said the intel raid adatper are all un dedected by proxmox installtion

please tell me how i can install the raid adatper or find a soultion since if i installed normal debian last version or centos 5.2 they dedect the raid adapter just fine
so it seems a kernel issue
regards

you need to specify the raid controllers you are talking about. otherwise no one can help.

thanks tom i forget that since i was stressted out

all of them are host raid adapters Adaptec AIC-7902W after research last night
i found out that they are not physical raid adapters they are just logic with no dedicated processor is that true?

tom i need a favor i need your recommendation for best raid adatper for sata drives since all our powerfull servers have sata arrays only

we need the adatpers to close the i/o issue we been suffering from since we went proudction
of course we will migrate in near future to FC disks & sas 15 k

but for now we need a soultion which would be powerfull raid sata adatper for performance i/o

yes, you got "fake raid" controllers.

take a look on this. (do not forget to order the optional BBU which is essential for reliable operation).

the ASM (the management software) works on Proxmox VE.

do you mean this one?

its a not totally bad but outdated (PCI-x interace). Actual server does not have a PCI-x slot anymore so please check if you really want to go for this.

AND you cannot attach SAS drives which is also a limitation.

maybe you can get an Adapted RAID 3805, not as good as 3508 but also SAS and SATA capable.
