Servicing performance and capacity-bound applications experiencing compounding storage management issues

These application profiles collide in the HPC data center 2 Sample Data Points

– Defensive I/O: Multi-Core = More Memory = More data to Checkpoint• Scalable, High-Performance WRITE-INTENSIVE storage is required• Low-Cost, High Density RAM (eg. MetaRAM) will only compound this problem

– Productive I/O: Data Volume is Exploding• CERN LHC will produce 27TB per day!• That data needs to be distributed to

SATA Usage & Capacity Increases Vulnerability Implications

The Appeal of SATA Technology:– Lower price per GB– Larger capacity– Lower power consumption– Less heat than Enterprise drives

Feature Enterprise-Class SATA

Rotational Speed 15,000 RPM 7,200 RPM

Capacity 400GB 1TB (1,000 GB)

Drive Defect List In hardware On media

# of CPUs 2 – one for I/O, one for mgmt 1 for everything

Prone to silent data corruption No Yes

Duty Cycle Continuous Non-continuous

Average Failure Rate Low High

The Trade-Off:Performance is 1/2 - 1/3 of SCSI SATA exacerbates storage issues

– Lower seek performance– Less reliability controls (mechanically)– Less robust electronically

Rebuild Times Grow w/ Capacity– Not Complimentary to Reliability– Many Drives not even dead

– Sick/Slow Drives are Common

The Physics of a Spindle:

Rebuild Time Hours Hours-Days

High Performance ComputingTraditional Storage Issues

We believe that traditional storage technologies are incapable of responding to the growing data challenge.

Issues with Issues with traditional storagetraditional storage in HPC in HPCSystems deliver substantially lower write performance than read Systems deliver substantially lower write performance than read performance – often ½ lessperformance – often ½ lessSystems are not designed to provide predictable I/O and handle failuresSystems are not designed to provide predictable I/O and handle failuresStriped storage environments realize degrading performance as the Striped storage environments realize degrading performance as the cluster grows – Amdahl’s Law cluster grows – Amdahl’s Law
