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 HNAS 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 Hitachi NAS 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 file module also 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. The 4040 cluster can scale up to 4PB of usable data storage and support 10GbE LAN access.

The storage configuration consisted of a Hitachi Unified Storage, model 150, system (HUS 150). The storage system was configured with dual symmetric active-active controllers and 32GB cache memory. There were 260 900GB 10K RPM SAS drives in use for these tests. There were 52 LUNs created using RAID-5, 4D+1P. There were eight 4Gbps FC ports in use across two controllers. The FC ports were connected to the 4040 nodes via a redundant pair of Brocade 6520 switches. The 4040 nodes were connected to each Brocade 6520 switch via four 4Gbps FC connections, such that a completely redundant path exists from each node to the storage. Each Hitachi NAS file module node has 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.
|Item No||Network Type||Number of Ports Used||Notes|
|1||10 Gigabit Ethernet||2||Integrated 10GbE Ethernet controller|
One 10GbE network interface from each 4040 node was connected to a Hitachi Apresia 15000-64XL-PSR switch, which provided network connectivity to the clients. The interfaces were configured to use Jumbo frames.
Each LG has a dual port Intel X520-SR2 PCIe 10GbE Server Adapter. But each LG connects only via a single 10GbE connection to the ports on the Hitachi Apresia 15000-64XL-PSR switch.

Each 4040 node has 8GB of main memory that is used for the operating system and in support of the FPGA functions. 22GB of memory is dedicated to filesystem metadata, sector cache and for other purposes. A separate, integrated battery-backed NVRAM module (2GB) on the filesystem board is used to provide stable storage for writes that have not yet been written to disk. The HUS 150 storage system was configured with 32GB Memory.
The Hitachi NAS File module 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 (32GB on each controller, total 64GB) 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 a power outage and never used as cache space.
The system under test consisted of two Hitachi NAS File Module 4040 nodes, connected to an HUS 150 storage system via two Brocade 6520 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.
The HUS 150 storage system consisted of 260 900GB 10K RPM SAS drives. All the connectivity from server to the storage was via two 4Gbps switched FC fabric. For these tests, there were 4 zones created on each FC switch. Each 4040 server was connected to each zone via 1 integrated 4Gbps FC ports (corresponding to 2 H-ports). The HUS 150 storage system was connected to 4 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.
