I like the idea of only one host seeing the SSDs at once, but a programatic way to flip them to the other host. This solves the fencing problem in ZFS nicely. Thanks for product reference. The Viking JBOF looks like what I need. -Chip ___ OmniOS-discuss mailing list OmniOS-discuss@lists.omniti.com http://lists.omniti.com/mailman/listinfo/omnios-discuss

To the host, the devices look like locally attached NVMe and there is no software changes required. Multiple hosts can connect, up to the PCIe port limits. If you use dual-port NVMe drives, then you can share the drives between any two hosts concurrently. Programming the switches is accomplished out-of-band by an HTTTP-based interface that also monitors the enclosure. In other words, if you want a NVMe equivalent to a dual-hosted SAS JBOD, the NDS-2244 is very capable, but more configurable. -- richard ___ OmniOS-discuss mailing list OmniOS-discuss@lists.omniti.com http://lists.omniti.com/mailman/listinfo/omnios-discuss
[OmniOS-discuss] NVMe JBOF
Has the NVMe support in Illumos come far enough along to properly support two servers connected to NVMe JBOF storage such as the Supermicro SSG-136R-N32JBF? While I do not run HA because of too many issues, I still build everything with two server nodes. This makes updates and reboots possible by moving a pool to the sister host and greatly minimizing downtime. This is essential when the NFS target is hosting 300+ vSphere VMs. Thanks! -Chip ___ OmniOS-discuss mailing list OmniOS-discuss@lists.omniti.com http://lists.omniti.com/mailman/listinfo/omnios-discuss
