The hyper-converged racks and appliances that I’ve been introducing to you in my blog posts about “Lego for the SAP data center of the future” are based on EMC ScaleIO or VMware VSAN. Whereas earlier we talked a lot about ScaleIO, I’d like to summarize here what’s up in SAP land regarding VSAN.
WHAT IS VSAN?
VSAN is enterprise-class native storage for VMware Hyper-Converged Software solutions. It clusters server-attached flash devices and/or hard disks to provide a flash-optimized, highly resilient shared datastore. VSAN is embedded within the hypervisor and can be configured as all-flash or hybrid storage, delivering over 6M IOPS with an all-flash architecture.
SAP SUPPORT STATUS FOR VSAN
At the time of writing SAP supports traditional SAP applications on VSAN (non-productive as well as productive). HANA is currently not supported, however there have been already successful validations and the HANA TDI KPIs are met. See here for more.
VMware is working with SAP to jointly determine the best approach to achieve SAP HANA support for Virtual SAN.
