It's really fast, flexible new technology and we don't have any bottlenecks due to speed
It's really fast, flexible and new technology. We don't have any bottlenecks due to speed. We can snapshot all the data to object storage and replicate it to another site using the object storage features. You can take as many snapshots as you want to back up all your data. There's no limit to cluster size, so you can grow as many WEKA cluster nodes as you want. Apart from snapshots of data to object storage, you can also tier the data, which is a different procedure. They can provide huge bandwidth or throughput to a single client. This is a very special platform for working with high-performance computing. You can use a server like a DGX or an NVIDIA and provide individual clients with almost 200 gigabytes per second. This is where PowerScale and Isilon have major limitations. We don't have such limitations with Weka. That's why it's been indicated for high-performance computing clusters. I'm very excited to work with this platform.
