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.

Fileset Size 9361.5 GB The storage configuration consisted of One Adaptable Modular Storage 2500 storage system (AMS2500) with eleven Expansion units; each expansion unit holding up to 15 drives. There were 160 SAS disk drives used for these tests. There were 32 LUNs created using RAID5, 4D+1P and formatted with 64KB Stripe Size. The expansion units connect to the AMS2500 controller by 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 ===================== Number of Ports Item No Network Type Used Notes ------- ------------ ---------------- ----- 1 10 Gigabit Ethernet 2 Integrated 1GbE / 10GbE Ethernet controller Network Configuration Notes --------------------------- One network interface from each 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.

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. 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 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 two Hitachi NAS Platform 3080 servers, connected to an AMS2500 storage system via two Brocade 5320 FC switches. The servers are configured in an active-active cluster, directly connected by a redundant pair of 10GbE connections to the cluster interconnect ports. The AMS2500 storage system consisted of 160 15K RPM SAS drives. All the connectivity from server to the storage was via a 4Gbps switched FC fabric. For these tests, there were 2 zones created on each FC switch. Each 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.

Uniform Access Rule Compliance ============================== Each load generating client hosted 32 processes, all accessing a single namespace on the HNAS 3080 cluster through a common network connection. There were 16 target filesystems (/w/d0,/w/d1.,/w/d15) 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/d15) and cycled through all the filesystems in sequence.
