So we have been saying how well the ZFSSA works in a VM environment for years. We tested and wrote a white paper on VMWare running on the ZFSSA back at Sun Microsystems well before being bought by Oracle. People still assume that now that we are Oracle, we must only work with Oracle's version of vitural machine but not true VMWare... I do hope our presence at VMWorld and this blog can help put those fears to rest. The ZFSSA KILLS the VMWare workload and we fully test and support it.
