Product Name Data ONTAP 8.1 Cluster-Mode (20-node FAS6240) Hardware Available Nov 2010 Software Available Sept 2011 Date Tested Sept 2011 SFS License Number 33 Licensee Locations Sunnyvale, CA USA Data ONTAP 8.1 Cluster-Mode extends the storage domain of a high-availability (HA) pair of controllers to multiple pairs of controllers. With Data ONTAP 8.1 Cluster-Mode, capacity scales from terabytes to tens of petabytes, all transparent to your running applications. Your storage is virtualized across as many as 24 nodes, managed as a single logical pool of resources and name space. Virtualizing your storage across multiple pairs of controllers provides nearly limitless scalability for even the most data-intensive environments, regardless of network protocol, SAN or NAS. Data ONTAP 8.1 offers the first massively scalable unified storage platform with support for FC, iSCSI, FCoE, NFS and CIFS.

An Options export policy was created giving full-access and applied to the file system. Filesystem Config 80 RAID-DP(Double Parity) groups of 17 disks each were created across all the disks. Fileset Size 146813.4 GB The storage configuration consisted of 20 nodes connected in 10 SFO (storage failover) pairs forming a single cluster. Each node was connected to its own and partner's disks. A single disk pool or "aggregate" was created on each node comprised of 4 RAID-DP raid groups, each composed of 15 data disks and 2 parity disks which held the data for the file-system. A separate aggregate consisting of 3 disks in a single RAID-DP group was created to hold the Data ONTAP operating system files. Each node was allocated a spare disk.A single virtual server or "vserver" was created on the cluster, spanning all physical nodes. A flexible volume was then created on the data aggregate of each node in the cluster. Each volume was junctioned at the root of the single namespace of the vserver. Each volume was striped across all the disks in the data aggregate. Network Configuration ===================== Number of Item Ports No Network Type Used Notes ---- ------------ --------- ----- 1 Jumbo frame 10 60 40 ports (2 per node) were used for the cluster Gigabit Ethernet network and 20 ports (1 per node) were used for the data network. Network Configuration Notes --------------------------- The two cluster ports from each node were connected to a pair of Cisco Nexus 5020 switches, one port to each switch to provision the cluster network. This provides high availability for the cluster network in case of port or link failure. One port from each node and each load generator was connected to a Cisco Nexus 5596 switch for the data network. The data and cluster networks were on separate subnets. All the ports (cluster and data) were configured to use jumbo frames. Benchmark Network ================= Each load generator was connected to the data network switch via a single 10GbE port. MTU size of 9000 was set for all connections to the switch.

The FlashCache module is a read cache used for caching filesystem data. A separate, integrated battery-backed RAM module is used to provide stable storage for writes that may not have been written to disk. Stable Storage ============== The WAFL filesystem logs writes and other filesystem data modifying transactions to the NVRAM adapter. In a storage-failover configuration, as in the system under test, such transactions are also logged to the NVRAM on the partner storage controller so that, in the event of a storage controller failure, any transactions on the failed controller can be completed by the partner controller. Filesystem modifying CIFS/NFS operations are not acknowledged until after the storage system has confirmed that the related data are stored in NVRAM adapters of both storage controllers (when both controllers are active). The battery-backed NVRAM ensures that any uncommitted transactions are preserved for at least 72 hours. In addition, de-staging to Flash on NVRAM preserves these transactions permanently. System Under Test Configuration Notes ===================================== he system under test consisted of 20 FAS6240 storage controllers and 60 storage shelves, each with 24 450GB SAS disk drives. The controllers were running Data ONTAP 8.1 software operating in Cluster-Mode. The storage controllers were configured in a storage failover (SFO) configuration and connected to their respective disk shelves in a multi-path high-availability (MPHA) configuration. The SFO was provided by the storage failover software option in conjunction with an InfiniBand interconnect provided on the NVRAM adapter. Each node has physical resources that can be shared across the cluster providing a single namespace. The cluster network (N1) is comprised of 2 Cisco Nexus 5020 switches to provide redundancy. The data network (N2) is comprised of a Cisco Nexus 5596 switch. Each node and load-generator have a single 10GbE port connected to this switch. The data and cluster networks are on separate subnets. All ports and interfaces on the data and cluster networks have Jumbo frames enabled. Other System Notes ================== All standard data protection features, including background RAID and media error scrubbing, software validated RAID checksum, and double disk failure protection via double parity RAID (RAID-DP) were enabled during the test.

Notes Load Generator Configuration Notes ---------------------------------- All clients accessed all mount points. Mount points were assigned to each client in a uniform manner making sure the load is evenly distributed across all clients and all interfaces. Uniform Access Rule Compliance ============================== For UAR compliance, each flexible volume was mapped to a subdirectory of the global namespace under root (/data1,/data2,...,/data20). Each volume was accessed over all data network interfaces (ip addresses ip1...ip20) such that each volume had a unique mount point on each node. This ensured that 1/20th of the total access on each node was done through a local interface and 19/20th of the total access was done through interfaces which were remote to the node the volume resides on. For these remote accesses, data traversed the cluster network. There were a total of 20 IP addresses available for data access, one per node. Each client mounted all 20 volumes using 12 different target IP addresses for a total of 240 mount points. The twelve IP addresses selected per client for mounting each volume was done in a round-robin manner from the list of 20 IP addresses such that each successive client used the next twelve IP addresses in the series. For example LG1 was assigned the following mount-point list: ip1:/data1, ip2:/data1,...,ip12:/data1,ip1:/data2,...,ip12:/data2,...,ip1: /data20,...,ip12:/data20. LG2 was assigned the following mount point list picking up next IP address in the list for each volume and circling back to the start of the series once the last IP was reached:ip13:/data1,ip14:/ data1,...,ip20:/data1,ip1:/data1,..,ip4:/data1,..,ip13:/data20,...,ip20:/ data20,ip1:/data20,..,ip4:/data20. This was repeated for all 30 clients. This ensured that data access to every volume was uniformly distributed across all clients and target IP addresses. The volumes were striped evenly across all the disks in the aggregate using all the SAS adapters connected to storage backend. Other Notes =========== Other test notes: None.
