Does anybody else have information to share about the latest incarnation of the P20 firmware ? The current released version is 20.00.07. The P20 problems were initially reported back in December 2014, so I wonder if LSI has resolved them in the meantime ? I'm currently running an all in one...

Disk power management in Solaris is a nice feature for home servers to spare energy and cost but it is almost impractical for larger zpools. The problem is that the disks of a sleeping pool are powered up sequentially instead of all in parallel. While this staggered spinup of a zpool could be a...

That's interesting. Can you confirm that SR-IOV is possible with the X9SCM-iiF ? So far I couldn't find a definitive statement about this, even not on Supermicros website. I also cannot see any configuration option in the BIOS to enable/disable SR-IOV ? I would be very interested to share a...

Under which OS are you running the latency tests ?

I did already elaborate on it in this post: http://hardforum.com/showpost.php?p=1039384469&postcount=103 What are the issues that you see ?

I would like to share my experiences around the X9SCM-iiF and ESXi 5.1 Config: X9SCM-iiF (the newer incarnation of the X9SCM-F with 2 x Intel 82574 NICs) Xeon E3-1240 V2 32GB RAM (Kingston KVR16E11K4/32) 3 x IBM M1015 flashed to LSI-SAS9211 IT mode firmware without OptionROM I had a...

I finally upgraded the X9SCM-iiF BIOS from version 2.0 to the latest version 2.0a and this solved the problem ! It also solved a problem with 3 LSI_SAS9211-8i controllers, which was the initial reason for the upgrade.

I agree regarding the SSD and the ZIL. Better disable sync writes and invest the money into a UPS. Now one thing I'm expecting to get flaming replies that the following is wrong :-) I've seen various posts in this forum stating that you need a good PSU with a lot of power for a storage...

I've opened a support ticket at Supermicro. However, so far it doesn't look like this will lead to a fix any time soon. I'm currently using the board under Openindiana, i.e. an Opensolaris derived distro based on Illumos and Supermicro support already told me that they don't have a lot of...

I can report a similar issue regarding the first onboard Intel 82574L ethernet port under Openindiana/Illumos on the X9SCM-Fii. During a large SMB file copy the interface gets dropped by the kernel. This does not happen when using the second onboard Intel 82574L ethernet port. So I would...

Thank you for your comments so far but in all honesty the intention of my post was not to discuss the probability of losing data when applying the sync=disabled setting. Let's simply assume that there are people out there paranoid enough to assume that shit will hit the fan. @stevebaynet...

I'm still wondering if a SSD used as a ZIL device really must have a super capacitor or any other means to assure that data in its volatile DRAM buffer is written to stable NAND Flash memory in case of a power loss. According to this blog post...
