The Hitachi Unified Storage (HUS) and Hitachi NAS (HNAS) Platform family of products provide multiprotocol support to store and share block, file and object data types. The 4000 series delivers best-in-class performance, scalability, clustering with automated failover, 99.999% availability, non-disruptive upgrades, smart primary deduplication, intelligent file tiering, automated migration, 256TB file system pools, a single namespace up to the maximum usable capacity, and are integrated with the Hitachi Command suite of management and data protection software. The HUS file module uses a hardware-accelerated "Hybrid Core" architecture that accelerates network and file protocol processing to achieve the industry's best performance in terms of both throughput and Operations per second. The HUS file uses an object-based file system (Silicon File System) and virtualization to deliver the highest scalability in the market, enabling organizations to consolidate file servers and other NAS devices into fewer nodes and storage arrays for simplified management, improved space efficiency and lower energy consumption. Each 4100 node or cluster can scale up 16PB of usable data storage and support 10GbE LAN access and 8Gbps FC storage connectivity.
Hitachi Unified Storage VM includes flash optimized system software and patented Hitachi Accelerated Flash to improve application performance. Utilizing external storage virtualization and automated tiering, HUS VM centralizes storage management of multiple storage tiers for the highest economic value.

The storage configuration consisted of one Hitachi Unified Storage VM All Flash storage system (HUS VM) configured with single chassis and 256GB cache memory. There were 64 1.6TB Hitachi Accelerated Flash module drives in use to meet the capacity and performance requirements of the benchmark. There were 64 LUNs created using RAID-5, 7D+1P. There were sixteen 8Gbps FC ports in use across two FED features located in different clusters. The FC ports were connected to the 4100 nodes via a redundant pair of Brocade 5320 switches. The 4100 nodes were connected to each Brocade 5320 switch via two 8Gbps FC connections, such that a completely redundant path exists from each node to the storage. Each Hitachi Unified Storage file module nodes have two internal mirrored hard disk drives that are used to store the core operating software and system logs. These drives are not used for cache space or for storing data.

One 10GbE network interface from each 4100 node was connected to a Hitachi Apresia 15000-32XL-PSR switch, which provided network connectivity to the clients. The interfaces were configured to use Jumbo frames.
Each LG has an Intel XF SR10GbE single port PCIe network interface. Each LG connects via a single 10GbE connection to the ports on the Hitachi Apresia 15000-32XL-PSR switch.

|Grand Total Memory Gigabytes||688|
Each 4100 node has 32GB of main memory that is used for the operating system and in support of the FPGA functions. 68GB of memory is dedicated to filesystem metadata, sector cache and for other purposes. A separate, integrated battery-backed NVRAM module (8GB) on the filesystem board is used to provide stable storage for writes that have not yet been written to disk. The HUS VM storage system was configured with 256GB Memory.
The Hitachi Unified Storage File node writes to the battery based (72 hours) NVRAM internal to the Server first. The data from NVRAM is then written to the backend storage system at the earliest opportunity, but always within a few seconds of arrival in the NVRAM. In a four node active-active cluster configuration, the contents of the NVRAM are synchronously mirrored (in a round robin fashion) to ensure that in the event of one or two node failover, any pending transactions can be completed by the remaining nodes. The data from the node is then written onto the battery backed backend storage system cache (a second layer of NVRAM in the entire solution) and are backed up onto the Cache Flash Memory modules in the event of a power outage. The Cache Flash Memory modules in the backend storage system are part of the total solution, but are used only during power outage and never used as cache space.
The system under test consisted of four Hitachi Unified Storage File 4100 nodes, connected to a HUS VM All Flash storage system via two Brocade 5320 FC switches. The nodes were configured in an active-active cluster mode and are connected by a redundant pair of 10GbE connections to the cluster interconnect ports via two Brocade TurboIron 24X 10GbE switches (cluster interconnect switches). The HUS VM All Flash storage system consisted of 64 1.6TB Hitachi Accelerated Flash module drives. All the connectivity from server to the storage was via two 8Gbps switched FC fabric. For these tests, there were 2 zones created on each FC switch. Each 4100 server was connected to each zone via 2 integrated 8Gbps FC ports (corresponding to 2 FC ports). The HUS VM storage system was connected to the 2 zones (corresponding to 16 FC ports) providing I/O path from the server to storage. The System Management Unit (SMU) is part of the total system solution, but is used for management purposes only and was not active during the test.
