Hi all, I've run into the classic NFS performance bottleneck when the ZIL is enabled and having no fast, dedicated ZIL device.
Being on a budget I concluded that an X25-E would be my best option, but there is still the concern that its write cache is not battery-backed and that a corrupt ZIL is a big problem. The server's power supply is backed by a UPS, but of course the PSU could just burn out. (I am also considering ACARD but don't yet have total confidence in its' reliability) What about powering the X25-E by an external power source, one that is also solid-state and backed by a UPS? In my experience, smaller power supplies tend to be much more reliable than typical ATX supplies. For example, something like this- http://www.addonics.com/products/power_adapter/aasaps.asp or even more reliable would be a PicoPSU w/ a hack to make sure that the power is always on. Has anyone tried something like this? Powering ZILs using a second, more reliable PSU? Thoughts?
