When comparing Tintri to VMware vSAN, it's important to note the fundamental differences in architecture. vSAN is representative of hyperconverged architectures, with storage and compute packaged together—this offers some very specific advantages and disadvantages outlined below. Tintri is all-flash storage and software that takes every action at the VM-level; a depth of granularity that has proven to enable greater automation and predictable performance with far less management effort.
|Node Configuration||Storage-only||Balanced storage and compute|
|Storage treatment||Dedicated hardware for storage||Storage shares resources with compute|
|Data services like snapshots, clones, replication at a VM Level|
|Optimized for High performance, High density, High Efficiency environments|
|Enhanced storage vMotion / live migration offload|
|Per Workload Headroom Visualization|
|Real-time analytics across storage, network and compute|
|Predictive analytics to forecast storage and compute requirements|
|Expand all-flash capacity one drive at a time|
|Scale storage independent of compute||Not Recommended|
|Automated rebalancing of VM placement to optimize use of resources|
|Inline Space savings (deduplication)||Limited||Inline Space savings (compression)|
|Minimal capacity overhead|
|No licensing tax|
|Snapshots without performance penalty|
|Workload isolation (auto-QoS)|
|Quality of service min / max|
|Multi-hypervisor support on a single system|
|Ability to backup to public cloud for long term retention|
|Address non-virtualized workloads|
The promise of vSAN is simplicity, since both storage and compute are delivered in one form factor—but, the reality is more complicated. vSAN requires expertise to deploy and manage. Conversely, Tintri goes from box to production in less than 30 minutes and can be managed by anyone in the data center in minutes per week. Tintri offers non-disruptive upgrades, whereas vSAN’s architecture requires you to evacuate each node as its updated—moving data off to other nodes without enough headroom can cause applications (or even entire nodes) to fail. Finally, Tintri’s comprehensive APIs allow it to be more tightly integrated with your entire virtualization ecosystem, even with public cloud. That makes it possible to automate workflows across components and further reduces management burden.
Where vSAN really falls down though is its ability to scale. vSAN recommends use of balanced nodes, so whenever an organization needs more of just storage or just compute, they have to purchase nodes that include both. Consequently, vSAN creates over-provisioning and unnecessary cost. Tintri allows customers to use best-in-class storage and compute, and to scale each separately as needed. As a result, Tintri scales to manage hundreds-of-thousands of VMs from one central console, while vSAN is limited to just 6,000 VMs.
If you’ve been considering vSAN for its supposed simplicity, it’s smart to consider Tintri for its ability to guarantee performance of every application and leverage automation to minimize management effort.
