The Hitachi NAS Platform, powered by BlueArc, Models 3080 and 3090 deliver best-in-class performance and scalability, Intelligent File Tiering, Clustered Namespace, greater than 128TB volumes, enterprise search enhancements, and integration with Hitachi Storage and data management products. Hitachi NAS Platform uses a Hybrid Core Architecture that accelerates processing to achieve the industry's best performance in both throughput and Operations per Sec. Performance, availability and scalability are further enhanced with the ability to grow to up to four nodes per cluster. Hitachi NAS Platform family delivers the highest scalability in the market which enables 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 Hitachi NAS Platform midrange model, HNAS 3080 and 3090, can scale up to 1PB or 2PB of usable data storage respectively. Both servers support simultaneous 1GbE and 10GbE LAN access, and 4Gbps FC storage connectivity.

160GB SATA 5400 RPM Disk Drives (Hitachi HTE543216L9A300). These two drives are used for storing the core operating system and management logs. No cache or data storage. 2 160.0 GB
Total 82 25.7 TB
Number of Filesystems 8
Total Exported Capacity 25.6TB
Filesystem Type WFS-2
Filesystem Creation Options 4K filesystem block size
dsb-count (dynamic system block) set at 768
Filesystem Config Each Filesystem was striped across 2 x 4D+1P, RAID-5 LUNs (10 disk drives).
Fileset Size 4716.7 GB

The storage configuration consisted of One Adaptable Modular Storage 2500 storage system (AMS2500) with six Expansion units; each expansion unit holding up to 15 drives. There were 80 SAS disk drives used for these tests. There were 16 LUNs created using RAID5, 4D+1P and formatted with 64KB Stripe Size. The expansion units connect to the AMS2500 controller via eight SAS links at 3Gb/s each. The AMS2500 dual controller storage system has sixteen 4Gbps FC ports connected to the 3080 server via a redundant pair of Brocade 5320 switches. The 3080 server is connected to each Brocade 5320 switch via two 4Gbps FC connections, such that a completely redundant path exists from server to the storage. Hitachi NAS Platform servers 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.

Network Configuration

Item No Network Type Number of Ports Used Notes
1 10 Gigabit Ethernet 1 Integrated 1GbE / 10GbE Ethernet controller

Network Configuration Notes

The network interface from the 3080 server was connected to a Force10 S2410 switch, which provided connectivity to the clients. The interface was configured to use default frames (MTU size of 1500 bytes).

Benchmark Network

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 Force10 S2410 network switch.

Memory Notes

The 3080 server has 12GB of main memory that is used for the operating system and in support of the FPGA functions. 14GB of memory is dedicated to filesystem metadata and sector caches. A separate, integrated battery-backed NVRAM module on the filesystem board is used to provide stable storage for writes that have not yet been written to disk. The AMS2500 storage system has a total of 32GB of cache across the dual controllers.

Stable Storage

The Hitachi NAS Platform server writes first to the battery based (72 hours) NVRAM internal to the Server. Data from NVRAM is then written to the Storage systems at the earliest opportunity, but always within a few seconds of arrival in the NVRAM. The data from the NAS is first written onto the cache in the AMS2500. The AMS2500 base unit contains four internal cache backup batteries, supports two external battery expansion units and when configured with full cache and batteries, it can preserve data in the cache for up to 96 hours.

System Under Test Configuration Notes

The system under test consisted of a single Hitachi NAS Platform 3080 server, connected to a AMS2500 storage system via two Brocade 5320 FC switches. The AMS2500 storage system consisted of 80 15K RPM SAS drives. All the connectivity from server to the storage were via a 4Gbps switched FC fabric. For these tests, there was a zone created on each FC switch. The Hitachi NAS 3080 server connected to each zone via 2 integrated 4Gbps FC ports (corresponding to 2 H-ports). The AMS2500 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 not active during the test.

Load Generator Configuration Notes

All the filesystems were mounted on all the clients, which were connected to the same physical and logical network.

Uniform Access Rule Compliance

Each load generating client hosted 16 processes. The assignment of processes to filesystems and network interfaces were done in such a way that they were evenly divided across all the filesystems and network paths.
