DataStax Academy FAQ

DataStax Academy migrated to a new learning management system (LMS) in July 2020. We are also moving to a new Cassandra Certification process so there are changes to exam bookings, voucher system and issuing of certificates.

@riehmc_178777 DataStax has partnered with VMware to test and determine the best configuration for running DataStax Enterprise on VMware vSAN 6.7 based on the high level of interest and demand from our customers. vSAN version 6.7 is required to enable the "host affinity" policy on all the VM disks.

I've personally heard anecdotal evidence from different users who have tried Nutanix but hasn't had consistent results with it at scale due to the shared storage not being able to meet the high IO demands.

I know of a couple of customers who have done some testing on SolidFire but their tests were small (3-5 nodes) and were seeing some good results on low throughput. I can't comment on how it would stand up with larger clusters and higher throughputs. In my personal experience, shared storage is problematic as more workloads get added and various apps/databases/technologies start competing with each other for IO. Your miles may vary so test with production-like workloads. Cheers!
