Oracle Exec Also Discusses Smart Scan to Help Solve Bottleneck Issues

Christopher Chelliah, general manager for Exadata and Appliance solutions, Oracle Asia Pacific, said the flash storage integration within the second iteration of Oracle’s Exadata Database Machine eliminates the need to source data from storage disks and cuts query processing time significantly. “Coupled with the hybrid columnar compression feature which groups data by column before compression, the flash storage can fit up to 50 terabytes of data,” said Chelliah, as reported by IDG.

Assessing Read/Write Performance as a Function of Workload

Infiniband IPoIB datalink partition and IP interface configuration is easy and painless using the same network BUI page or CLI contexts as ethernet, says Fishworks blogger Cindi in her update on “Infiniband for Q3.2009.” Port GUID information is available for configured partitions on the network page, she continues, which makes it easy to add Sun Storage 7000 Unified Storage System HCA ports to a partition table on a subnet manager.

Aggregate up to 72 QDR 4x Ports into a Single 1RU Switch 

The Sun Datacenter InfiniBand Switch 72 joins the Sun Datacenter InfiniBand Switch 648 and Sun Datacenter InfiniBand Switch 36 in Sun’s third generation family of InfiniBand (IB) switches. The one rack unit (RU) switch is a complete, ultra-slim, ultra-dense switch fabric solution for Sun server clusters up to 72 Quad Data Rate (QDR) IB nodes. Most importantly, the switch integrates with the Sun Blade 6048 InfiniBand QDR Switched Network Express Module, scaling up to over 576 end nodes.

Self-contained, Multi-purpose 36-node, QDR InfiniBand Switch Fabric Solution

The Sun Datacenter InfiniBand Switch 36 is a 36-port Quad Data Rate (QDR) InfiniBand leaf switch enabling users to bind Sun Blade and Sun Fire servers and storage systems into a 36-node cluster. This multi-purpose switch can act as a self-contained fabric solution for smaller InfiniBand clusters or as a building block for hierarchical fabric topologies supporting larger clusters of Sun Blade or Sun Fire servers and storage systems.

High-density, QDR, Standards-based, Fully Non-blocking IB Core Switch

The Sun Datacenter InfiniBand Switch 648 is a high-density, Quad Data Rate (QDR) IB core switch that offers capacity for up to 648 servers and storage systems. It can replace up to 152 discrete switching elements and thousands of cables in large-scale solutions, Sun reports. It is an ideal solution for cluster sizes that range from 200 servers to 5000+ servers. This full industry standard Infiniband switching platform fits into a standard 19-inch rack. With an 11u height, up to three switches can be mounted in a single rack for 1,944 4x QDR InfiniBand ports in 33 rack units.

Also Meet the Sun InfiniBand Dual port 4x DDR PCIe Fabric Expansion Module (FEM)

Sun is introducing its Sun Blade 6048 InfiniBand Quad Data Rate (QDR) Switched Network Express Module (NEM) and the Sun InfiniBand Dual port 4x DDR PCIe Fabric Expansion Module (FEM). Expected to be generally available this summer, what these new upcoming Sun products boast are QDR InfiniBand which delivers up to 80 Gb/s bandwidth (full-duplex) per server connection and the ability to enable Sun Blade server modules to be connected to an in-chassis InfiniBand fabric.

Available as Low Profile and Express Module HCAs

Sun InfiniBand Dual Port 4x Quad Data Rate (QDR) PCIe Low Profile Host Channel Adapter (HCA) and the Sun InfiniBand Dual port 4x QDR PCI-E Express Module HCA are built using Mellanox ConnectX silicon, delivering QDR over four times than copper and optical interconnects, Sun reports. Sun’s QDR InfiniBand products enable Sun to offer RDMA-based high-performance, low-latency I/O interconnect technology for its blade and rack mount server platforms.

New Servers, Integrated Open Storage and High-performance Networking

At the Sun Open Network Systems launch, the company introduced servers, integrated open storage, and high-performance networking designed for the HPC market as well as other customers wanting to take advantage of high performance technology capabilities that address high performance, high throughput, large memory, and fast I/O. Sun reports that with these new HPC systems, customers can simplify their environment from less highly integrated solutions — reducing cabling by 84 percent, switches by 97 percent, and rack space by 75 percent.
