Reliability challenges for storing exabytes

Abstract: Abstract-As we move towards data centers at the exascale, the reliability challenges of such enormous storage systems are daunting. We demonstrate how such systems will suffer substantial annual data loss if only traditional reliability mechanisms are employed. We argue that the architecture for exascale storage systems should incorporate novel mechanisms at or below the object level to address this problem. Our argument for such a research focus is that focusing solely on the device level will not scale, and … Show more

“…Unlike aforementioned RAID-6 codes, which are all horizontally aligned, -code [6] stands out as a vertical code and has the unique property in update complexity, which is denoted by the penalized writes to parity caused by a write request to a single data element. Additionally, nonvolatile memory (NVM) is gaining Mobile Information Systems popularity and much sensitive to write operation [12]. With its born optimality on update penalty, -code is very suitable to be used in nonvolatile memory systems for its optimal update complexity to mitigate write operations.…”

“…(i) Existing codes assume that failures are independent, instantaneous, and occurrences of failures conform to the exponential distribution [11,12]. This ideal assumption does not apply to the fault pattern of modern storage systems [13].…”

“…It brings a challenging problem, which is how to efficiently store all that data on a Cloud scale. Modern Cloud-scale storage systems that store EB-scale (10 18 or 2 60 bytes) data [1,2], separate file data access and metadata transactions to achieve high performance and scalability. EB-scale data is managed with a distributed storage system in a data center to support many computations, e.g., the large synoptic survey telescope 2 , in which there are more than 10…”
