Silicon Graphics Inc. (SGI) (NYSE: SGI) and Legato Systems Inc. (Nasdaq: LGTO) are touting test results they claim show their products performing backup at a blistering 10 Tbytes per hour -- nearly three times faster than the previously claimed record.
There were no tricks up their sleeves, says Craig Schultz, storage product manager at SGI. "We've used real-world applications and data," he says. "These are the actual results -- they're not extrapolated... We didn't extract this and say what it could be or would be."
Fair enough. But check out the ultra-high-end configuration of the SGI Origin 3000 used in the test: It had 32 MIPS processors and eight I/O modules for a total of 48 2-Gbit/s Fibre Channel connections.
That's just for starters on what easily looks like a million-dollar-plus SAN (the companies did not disclose how much all the equipment used on the test would cost). The primary data was hosted on an SGI TP9500 storage array that is a rebranded version of an LSI Logic Storage Systems Inc. array with 17 Tbytes of disk. The data was backed up to (and restored from) a Storage Technology Corp. (StorageTek) (NYSE: STK) PowderHorn 9310 library with 48 T9940B tape drives. The server, storage, and tape library were connected via 2-Gbit/s Brocade Communications Systems Inc. (Nasdaq: BRCD) switches configured in a redundant 120-port SAN fabric.
The data set used in the test was provided by one of SGI's customers, Geophysical Fluid Dynamics Laboratory, the weather research arm of the U.S. government's National Oceanic and Atmospheric Administration. The total size of the data set was 10.297 Tbytes, comprising files ranging in size from 2 to 42 Gbytes.
To realize the benefits of cloud-native software, an application must actually be cloud-native—designed to run in the cloud, interacting with disaggregated cloud services, fully manageable as code—to deliver the expected benefits.
