Exomium S200 and DSS V6 and LSI 9265i and Cachecade -> Data corruption

[To-M]

I don't believe this is true.

We have 1000's of V6 and V7 in production and we would have updated the LSI Megaraid SAS drivers from the LSI release notes if this was true.

I have checked our support DB and have not found any records of this associated with any support tickets of this issue. What was the ticket that Open-E stated the same as LSI?

We don't make the driver and the Cachecade is an addon feature to certain LSI controllers. Normally the firmware would control the Cachecade along with some parts of the driver to perform the algorithms it uses for hot data.

I would also like to know the case w/ LSI where they stated this, you can submit a support ticket to Open-E with the contact information.

We have several webinars about the LSI Cachecade and I did one with the LSI engineer in March 28th of 2012 and nothing was mentioned about a out dated driver that can cause corruption.

Again we don't make the drivers, the vendors do so DSS would not be involved here. If there was corruption then it could be where the SSD for the cache was a RAID 0 and not a RAID 1 thus if losing the SSD in a RAID 0 then yes you can have corruption for the Writes at that time the SSD went bad but not for the Reads.
