An Efficient Hybrid I/O Caching Architecture Using Heterogeneous SSDs
Reza Salkhordeh, Mostafa Hadizadeh, Hossein Asadi
SSDs are emerging storage devices which unlike HDDs, do not have mechanical parts and therefore, have superior performance compared to HDDs. Due to the high cost of SSDs, entirely…
LBICA: A Load Balancer for I/O Cache Architectures
Saba Ahmadian, Reza Salkhordeh, Hossein Asadi
In recent years, enterprise Solid-State Drives (SSDs) are used in the caching layer of high-performance servers to close the growing performance gap between processing units and st…
Modeling Impact of Human Errors on the Data Unavailability and Data Loss of Storage Systems
Mostafa Kishani, Hossein Asadi
Data storage systems and their availability play a crucial role in contemporary datacenters. Despite using mechanisms such as automatic fail-over in datacenters, the role of human…
Evaluating Impact of Human Errors on the Availability of Data Storage Systems
Mostafa Kishani, Reza Eftekhari, Hossein Asadi
In this paper, we investigate the effect of incorrect disk replacement service on the availability of data storage systems. To this end, we first conduct Monte Carlo simulations to…
An Operating System Level Data Migration Scheme in Hybrid DRAM-NVM Memory Architecture
Reza Salkhordeh, Hossein Asadi
With the emergence of Non-Volatile Memories (NVMs) and their shortcomings such as limited endurance and high power consumption in write requests, several studies have suggested hyb…
ReCA: an Efficient Reconfigurable Cache Architecture for Storage Systems with Online Workload Characterization
Reza Salkhordeh, Shahriar Ebrahimi, Hossein Asadi
In recent years, SSDs have gained tremendous attention in computing and storage systems due to significant performance improvement over HDDs. The cost per capacity of SSDs, however…
ECI-Cache: A High-Endurance and Cost-Efficient I/O Caching Scheme for Virtualized Platforms
Saba Ahmadian, Onur Mutlu, Hossein Asadi
In recent years, high interest in using Virtual Machines (VMs) in data centers and Cloud computing has significantly increased the demand for high-performance data storage systems.…
Investigating Power Outage Effects on Reliability of Solid-State Drives
Saba Ahmadian, Farhad Taheri, Mehrshad Lotfi +2
Solid-State Drives (SSDs) are recently employed in enterprise servers and high-end storage systems in order to enhance performance of storage subsystem. Although employing high spe…
