DRAM is used as an extremely low latency cache of the most recently read or written data and metadata.
NVDIMMs are the lowest latency type of storage and are used to store metadata transaction and user data logs.
High-performance SSDs provide low-latency access and high-bandwidth storage for the metadata data- base.
SATA or SAS SSDs provide cost-effective and high-bandwidth storage and store small component objects.
HDDs provide high-bandwidth data storage at a low cost and are used to store large component objects.
Using both industry-standard self-encrypting SATA SSDs and hard disk drives (SEDs), ASU-150 nodes provide hardware-based encryption with zero performance impact and support complete cryptographic erasure of both types of SEDs upon command.
ASU-150 nodes are managed as part of the PanFS solu- tion. No matter how many ASU-150 nodes you add, all nodes in the realm are managed from one graphical user interface (GUI) or command-line interface (CLI).
The ASU-150 is the industry’s best price/performance parallel file system solution. Because PanFS has a scale-out archi- tecture, the system’s storage capacity, DRAM caching, and network bandwidth all grow incrementally and linearly as you add more storage nodes.
The PanFS file system delivers data in parallel from storage nodes to the application, multiplying the bandwidth an ap- plication can achieve to a single file. Data flows directly from storage nodes to the application without any hops through intermediate servers or extra network links.
