They probably will, but I can't say for sure. I would recommend going with a class 10 card though.
Here is what I know about the IDSDM: It has no stated size limitations on SD cards. We only sell 1GB SD cards with it(on the R815). The 2GB SD card is listed as a valid replacement for the 1GB cards in my parts database for the R815.
There is not a lot of specs available on the IDSDM. It appears to be an extremely basic pass-through/converter that takes SD cards and presents them as USB 2.0 devices to the system board. According to documentation the IDSDMs in 11th and 12th generation servers are identical in functionality. I have 2GB SD modules in my R720. Based on all of this information 1 and 2GB modules should work without issue. Nothing states that larger sizes will not work, but we don't sell them in that configuration. The 8GB module is intended for Vflash. Here are the part numbers I have listed on the R815. You will need to call spare parts to order these:
0XW5C - 8GBIntended for Vflash(Vlash can use any size card up to 8GB) 738M1 - 2GBIntended for Vflash, but listed as a valid replacement for 1GB Modules P789K - 1GBIntended for SD Module RX790 - 1GBIntended for SD Module
The 8GB modules will likely work, but I would recommend testing before buying them for all of your servers. I'm sorry I can't be more specific, but the most detailed information I can locate on size limitations is in the technical guide book under SD module size it lists: Multiple.
1. Can I use any SD cards? Is there a size limit? I want to have the 2 cards in high availability. I believe there is a BIos setting to do that.
Yes, there is an optional Internal Dual SD Module for the R815. There is an option in the BIOS for mirrored mode on the modules. I doubt every SD card will work. The SD cards we have validated are Kingston 1GB, 2GB, and 8GB.
The IDSDM presents the SD cards to the system as USB 2.0 devices.
nid15: Did you ever try this? I'm considering a 32GB or 64GB SD card to see if I can install Hyper-V to an internal memory card and I'm trying to spec a card out with the best change of success. Any other thoughts?
Just because this thread still turns up in google for this server. Don't put large SD cards in these. The mirroring process has to be done during post and takes a *minimum* of 3 minutes per GB, so that 16GB card has it sitting at post for 48 minutes to do the mirror. It's also super fussy/fragile I only use it for /boot for an NVME drive setup and updating takes forever with it freezing when writing to /boot (rest of the system continues OK, it's just super slow) and after running update it sometimes kicks a card out of the redundancy. I'm going to get some SLC 1GB cards to replace the kingston/sandisk 16Gb cards I got as a result of this, hopefully that'll help with the issues.

Thank You. Will either of these work or can I buy them from Dell?
