The follow discussions and presentations will take place during the OCP Storage session:
Chassis Design Best Practices to Optimize Hard Drive I/O Performance - Richard Repp (Seagate)
Rich will present Seagate's best practices for chassis design and validation testing as it relates to the sensitivities of HDD I/O. This presentation will cover common issues encountered in chassis design that affect HDD I/O and then discuss some simple ways to avoid these issues.
Cloud Storage Challenges and Opportunities - Dimitar Boyn i/o Switch
Dimitar will speak about "Cloud Storage Challenges and Opportunities". In particular, he will explain key limitations of current technologies including (1) SAN and NAS, (2) SSD and (3) software defined storage (SDS). Each technological limitation points to new thinking and new opportunities.
For example, it is mathematically demonstrable that RAID data protection cannot scale to multi-petabyte arrays, i.e., it literally does not work and data is not protected, and, even if it did work, rebuilding a 4 TB or 6 TB or soon a 12 TB hard drive takes so long that there is a significant window for additional drive failures. Big data solutions obfuscate this problem but make no attempt to solve it. The correct solution lies in new data protection algorithms. Amplidata, CleverSafe and Scality offer data protection based on erasure coding (EC) or Reed-Solomon algorithms. While EC may be "the new RAID" actual implementations are largely in the form of software defined storage (SDS) solutions. In the cloud, the need for SDS is unclear because its value proposition includes making disparate storage resources homogeneous, but that is a value proposition for enterprises. At the same time, enterprises will never universally adopt SDS, which is arguably an elaborate Band Aid. What is needed are new open standards.
