Online searching suggests the TRIM function is not supported on most RAID controllers. Even though we can't confirm if that's the case for LSI 9260-8i*, this shouldn't be a problem for the drives or the RAID volume.
The Intel® SSD DC S3510 Series was designed for Data Center environments, where TRIM optimization is not always an option. To compensate, Intel® Data Center SSDs have additional space so the data can be moved and the impact of not having TRIM is down to a minimum, this is done automatically.
Please let us know if there's anything else we can do for you.
