An Analysis on Empirical Performance of SSD-Based RAID
نویسندگان
چکیده
In this paper, we measure the I/O performance of five filesystems— EXT4, XFS, BTRFS, NILFS2, and F2FS, with five storage configurations— single SSD, RAID 0, RAID 1, RAID 10, and RAID 5. We show that F2FS on RAID 0 and RAID 5 with eight SSDs outperforms EXT4 by 5 times and 50 times, respectively. We also make a case that RAID controller can be a significant bottleneck in building a RAID system with high speed SSDs.

Building Large Storage Based On Flash Disks
Flash SSDs are a technology that has the potential of drastically changing the architecture of a DBMS. In this paper we examine the properties of a storage space built on SSDs with RAID and how these affect data intensive systems. While we observed the expected performance improvements of one to two orders of magnitude of SSD-only storage over HDD storage, RAID-SSD systems showed interesting ef...
متن کاملLinux Software RAID Level 0 Technique for High Performance Computing by using PCI-Express based SSD
The Linux-based legacy server systems are configured and used with software RAID to improve the performance of the disk I/O. Server systems requiring high performance prefer a special SSD that connects directly with the PCI-express bus to the SATA interface. However, the problem is that the current Linux kernel and software RAID are difficult to optimize the high-performance SSD based on PCI-Ex...
متن کاملThe Tail at Store: A Revelation from Millions of Hours of Disk and SSD Deployments
We study storage performance in over 450,000 disks and 4,000 SSDs over 87 days for an overall total of 857 million (disk) and 7 million (SSD) drive hours. We find that storage performance instability is not uncommon: 0.2% of the time, a disk is more than 2x slower than its peer drives in the same RAID group (and 0.6% for SSD). As a consequence, disk and SSD-based RAIDs experience at least one s...
متن کاملAugmenting RAID with an SSD for Energy Relief
In this paper, we describe a design of a novel architecture for RAID that uses an SSD as a large cache to conserve energy. This approach stems from the fact that short term footprints are small enough to be efficiently managed within an SSD. More specifically, in this study, we consider two simple approaches to reduce the energy consumed in RAID. First, when a read happens in RAID, a copy of th...
متن کاملEnabling TRIM Support in SSD RAIDs
Deploying solid state drives (SSDs) in RAID configurations can leverage the performance of persistent storage systems into a new dimension. However, the Achilles’ heel of SSDs and, therefore, also SSD RAIDs is their write performance, especially for small random requests. To prevent a degradation of the write throughput, it is important to maintain an adequate amount of free flash capacity. Thi...
