The Farce of Hyper-converged Blog Wars – No Real Numbers, Just Talk!

Nutanix appears to be charging a very hefty premium for largely equivalent configurations. Even with aggressive discounting, there’s a vast gulf in relative pricing.

Chuck Hollis, VMware

EVO:RAIL is struggling and close to getting dumped. VSAN has seen a bit more success but it isn’t a substantial part of VMware’s business, or a replacement for EMC’s declining

sales.

Lukas Lundell, Nutanix

Nutanix offers substandard performance running data center workloads when compared to both external storage arrays and especially an equivalently configured VSAN cluster.

Industry standard, independently verified benchmark for I/O performance

► Can be compared with storage systems as well

DataCore hyper-converged can be used for mission- & business-critical workloads

► Suitable for Oracle, MS SQL Server & SAP HANA► Removing I/O Bottleneck means higher VM density

• More VMs on same hardware for VDI

Virtualized Shared Storage


Expand storage capacity by adding servers► Compute, memory, storage capacity & storage performance all tied together► Is your data growing at the same rate as your compute?► What if you don’t need more compute / memory?

Yet another Storage silo► Each cluster is separate from other clusters► Virtualized and Physical hosts are separate data islands► Doesn’t work with SAN/NAS

DataCore TCO Summary


Background Large restaurant chain with over 1,000 locations All key applications run locally

► Point of sale, order scheduling, etc Application downtime meant site closure (temporary)

► Loss of revenue and poor customer satisfaction

Requirement Lowest cost infrastructure for high availability

40

Case Study 1 – ROBO


Lowest TCO Only 2 servers for HA per location RAM provides I/O acceleration so Flash not needed Runs natively in Windows, no extra license

Easy Management Multi-site automated deployment with simple wizards Integrates with Microsoft System Center Extensive instrumentation for centralized monitoring

41

Reasons for SelectingDataCore Virtual SAN


Background Mid-sized Hospital Virtualizing PBX (voice communications), which was 12 physical servers

Requirements Reliable performance, as voice communication is a Tier 1 application Physical storage and compute footprint across 2 separate buildings

(geographically separated) for high availability

42

Case Study 2 – Application Cluster


VMware VSAN Requires 4 hosts

Only works at single site

Requires Flash on servers

DataCore Virtual SAN Only requires 2 hosts

Stretch cluster with only 2 nodes

Flash is optional (RAM is faster)
