The Avere Systems FXT 3800 Edge filer appliance provides Hybrid NAS storage that allows performance to scale independently of capacity. The FXT 3800 is built on a 64-bit architecture that is managed by Avere OS software. FXT Edge filer clusters scale to as many as 50 nodes, support millions of IO operations per second, and deliver over 100 GB/s of bandwidth. The Avere OS Hybrid NAS software dynamically organizes data into RAM, SSD and SAS tiers. Active data is placed on the FXT Edge filer while inactive data is placed on the Core filer that is optimized for capacity. The FXT 3800 accelerates performance of all read, write, and directory/metadata operations, and supports both NFSv3 and CIFS protocols. The AvereOS Local Directories feature enables the Avere Edge filer cluster to immediately acknowledge all filesystem updates and later flush the directory data and user data to the Core filer. The tested configuration consisted of (32) FXT 3800 Edge filer nodes. The system also included (1) OpenSolaris ZFS server in the role of a single Core filer mass storage system exporting a single filesystem. A WAN simulation kernel module was configured into AvereOS to introduce 150 milliseconds of WAN latency (75 milliseconds in each direction) for all communications with the Core filer, thus simulating a cloud storage infrastructure. In this configuration, Avere's AOS presents a single filesystem to all clients and provides instantaneous responses to client operations, despite the 150 millisecond network roundtrip times present with all communications to the Core filer.

Network Configuration

Item No Network Type Number of Ports Used Notes
1 10 Gigabit Ethernet 32 One 10 Gigabit Ethernet port used for each FXT 3800 Edge filer appliance.
2 10 Gigabit Ethernet 1 The Core filer storage system is connected via 10 Gigabit Ethernet with simulated latency of 150ms (75ms each direction.)

Network Configuration Notes

Each FXT 3800 was attached via a single 10 GbE port to one Gnodal GS7200 72 port 10 GbE switch. The load generating clients were attached to the same switch. The Core filer storage servers were also attached to the same switch. A WAN simulation software module on the FXT 3800 system was configured to inject 150ms (75ms in each direction) of WAN latency between the Avere Edge filer cluster and the Core filer. A 1500 byte MTU was used throughout the network.

Benchmark Network

An MTU size of 1500 was set for all connections to the switch. Each load generator was connected to the network via a single 10 GbE port. The SUT was configured with 32 separate IP addresses on one subnet. Each cluster node was connected via a 10 GbE NIC and was sponsoring 1 IP address.

Memory Notes

Each FXT node has main memory that is used for the operating system and for caching filesystem data. Each FXT contains two (2) super-capacitor-backed NVRAM modules used to provide stable storage for writes that have not yet been written to disk.

Stable Storage

The Avere filesystem logs writes and metadata updates to the PCIe NVRAM modules. Filesystem modifying NFS operations are not acknowledged until the data has been safely stored in NVRAM. In the event of primary power loss to the system under test (SUT,) the charged super-capacitor provides power to the NVRAM circuitry to commit the NVRAM log data to persistent flash memory on the NVRAM card. The NVRAM log data is indefinitely persisted to on-board flash memory. When power is restored to the SUT, the NVRAM log data is restored from the persistent on-board flash to the NVRAM subsystem, and during startup, AvereOS replays this log data to the on-disk filesystem thus assuring a stable storage implementation. The above described implementation handles cascading power failures in the same manner: persist NVRAM to stable flash upon power failure, restore NVRAM log data from flash and replay logs to filesystem upon power-on.

System Under Test Configuration Notes

The system under test consisted of (32) Avere FXT 3800 nodes. Each node was attached to the network via 10 Gigabit Ethernet. Each FXT 3800 node contains (13) 600 GB SAS disks and (2) 400GB eMLC SSD drives. The OpenSolaris Core filer storage system was attached to the network via a single 10 Gigabit Ethernet link. The Core filer storage server was a 4U Supermicro server configured with a software RAIDZ 21+2 RAID6 array consisting of (23) 4TB SATA disks. There were (2) additional JBOD shelves, each with (23) drives and SAS connectivity to the Core filer. Each ZFS filesystem consisted of (3) RAIDZ2 sets totaling (69) 4TB SATA disks.

Uniform Access Rule Compliance

Each load-generating client hosted 512 processes. The assignment of 512 processes to 32 network interfaces was done such that they were evenly divided across all network paths to the FXT appliances. The filesystem data was evenly distributed across all disks and FXT appliances and Core filer storage servers.
