1 Samba 1,a) cache tiering Samba 1% 81% 71% offset 10 offset write 88% 10 tiering cache tiering cache SSD cache tiering Samba workload analysis and consideration for hybrid storage system Kazuichi Oe 1,a) Takeo Honda 2 Motoyuki Kawaba 1 Abstract: We investigated spatial locality and duration-dependent characteristics of storage accesses using commercial workload on Samba in order to build a cost-effective hybrid storage system, which can harness caching and tiering appropriately. The experimental result unveils that 81% of the loads arose on 1% of the storage area, and 71% of the concentrated loads were migratory, that is, the loads tend to hop to different areas after they continue for a couple of minutes to 10 minutes at arbitrary offsets. Additionally, we discovered that the ratio of r/w was quite high (88%). Based upon the above results, this paper discussed the effectiveness of a control technique that utilizes caching and tiering appropriately according to load duration. For instance, it may handle only loads that continue for more than 10 minutes with tiering and the others with caching. We believe that this technique can widely be used for hybrid storage systems.
