The Hitachi Unified Storage (HUS) and Hitachi NAS (HNAS) Platform family of products provide multi protocol 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 uses an object-based file system (SiliconFS) 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 4080 node can scale up 16PB of usable data storage; support 10GbE LAN access and 8Gbps FC storage connectivity.

The storage configuration consisted of one Hitachi Unified Storage VM storage system (HUS VM) configured with single chassis and 128GB cache memory. There were 448 15K RPM SAS disks in use for these tests. There were 112 LUNs created using RAID-5, 3D+1P. There were eight 8Gbps FC ports in use across 2 FED features located in different clusters. The FC ports were connected to the 4080 nodes via a redundant pair of Brocade 5320 switches. The 4080 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. Hitachi Unified Storage file module nodes have two internal mirrored hard disk drives which are used to store the core operating software and system logs. These drives are not used for cache space or for storing data.

Two 10GbE network interfaces from each 4080 node were connected to a Brocade TurboIron 24X switch, which provided network connectivity to the clients. The interface was configured to use Jumbo frames.
Each LG has an Intel XF SR 10GbE single port PCIe network interface. Each LG connects via a single 10GbE connection to the ports on the Brocade TurboIron 24X network switch.

|Grand Total Memory Gigabytes||220|
Each 4080 node has 16GB of main memory that is used for the operating system and in support of the FPGA functions. 26GB of memory is dedicated to filesystem metadata, sector cache and for other purposes. A separate, integrated battery-backed NVRAM module (4GB) 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 128GB Memory.
The Hitachi NAS Platform 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 an active-active cluster configuration, the contents of the NVRAM are synchronously mirrored to ensure that in the event of a single node failover, any pending transactions can be completed by the remaining node. 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 is used only during power outage and not used as cache space.
The system under test consisted of two Hitachi Unified Storage file module 4080 nodes, connected to an HUS VM storage system via two Brocade 5320 FC switches. The nodes are configured in an active-active cluster mode, directly connected by a redundant pair of 10GbE connections to the cluster interconnect ports. The HUS VM storage system consisted of 448 15K RPM SAS 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 4080 server was connected to each zone via 2 integrated 8Gbps FC ports (corresponding to 2 H-ports). The HUS VM storage system was connected to the 2 zones (corresponding to 8 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.

All clients were connected to one common namespace on the server cluster, connected to a single 10GbE network.
Each load generating client hosted 96 processes, all accessing a single namespace on the 4080 cluster through a common network connection. There were 8 target file systems (/w/d0, /w/d1, /w/d2, /w/d3, w/d4, /w/d5, /w/d6, /w/d7) that are presented as a single cluster namespace through virtual root (/w), accessible to all clients. Each load generator was mounted to each filesystem target (/w/d0, /w/d1, /w/d2, /w/d3, /w/d4, /w/d5, /w/d6, /w/d7) and cycled through all the file systems in sequence.
