The Avere Systems FXT 3800 Edge filer running AvereOS V4.0 with FlashCloud™ provides Cloud NAS storage that enables performance scalability at the edge while leveraging object-based Cloud storage capacity at the core. The Amplidata AmpliStor object-based software defined storage platform delivers very high data durability, scalability from petabytes to exabytes, and much higher efficiency than replication. The AvereOS Hybrid NAS software dynamically organizes hot data into RAM, SSD and SAS tiers, retaining active data on the FXT Edge filer, and placing inactive data on the object-based Cloud Core filer. The FXT Edge filer managed by AvereOS software provides a global namespace, clusters to scale to as many as 50 nodes, supports millions of I/O operations per second, and delivers over 100 GB/s of I/O bandwidth. The FXT 3800 is built on a 64-bit architecture that provides sub-millisecond responses to NFSv3 and CIFS client requests consisting of read, write, and directory/metadata update operations. The AvereOS FlashCloud functionality enables the Avere Edge filer to immediately acknowledge all filesystem requests, and flush inactive directory data and user data to the object-based Cloud Core filer. The tested Edge filer configuration consisted of (3) FXT 3800 nodes backed by object-based Cloud Core filer storage. The object-based Cloud Core filer storage config, an Amplidata AmpliStor system, consisted of (3) AC4 Controller Nodes and (8) AS36 Storage Nodes.

3 1 Gigabit Ethernet 8 The Amplidata AS36 systems each have a 1 Gigabit Ethernet port.

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 generator client was attached to the same switch via 10 GbE interface. The Amplidata AmpliStor object-based storage system was connected to both 10 GbE and 1 GbE switches. The AC4 Controller nodes were attached to the network via 10 Gigabit Ethernet. The AS36 Storage nodes were attached to the network via 1 Gigabit Ethernet. A 1500 byte MTU was used on the network.

Benchmark Network

An MTU size of 1500 was set for all connections to the switch. The Gnodal and ProCurve switches were linked connected with a 10 GbE inter-switch link. The load generator was connected to the network via a single 10 GbE port. The SUT was configured with 3 separate IP addresses on one subnet. Each Avere Edge filer 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. Each AmpliStor node has system memory that is used for the operating system and for managing the object name-space.

Stable Storage

The Avere filesystem logs writes and metadata updates to the NVRAM module. Filesystem modifying NFS operations are not acknowledged until the data has been safely stored in NVRAM. The super-capacitor backing the NVRAM ensures that any uncommitted transactions are committed to persistent flash memory on the NVRAM card in the event of power loss. The Amplistor system, configured with 20/4 BitSpread, acknowledges PUT requests once 16 out of 20 parts of the erasure-coded object data have been synchronously committed to disk.

System Under Test Configuration Notes

The system under test consisted of (3) 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 Amplidata AmpliStor object-based Cloud Core filer storage system consists of AC4 Controller nodes and AS36 Storage nodes. The controller nodes were attached to the network via 10 Gigabit Ethernet. The storage nodes were attached to the network via 1 Gigabit Ethernet.
