NetApp announced that it will provide additional data volume reduction mechanism in ONTAP v9.0, what exactly is it? Can NetApp's 4KB block write technology really hold more data? Three astronauts crowded into Soyuz capsules to return to Earth from orbit - a notion that is quite similar to NetApp's IO processing. This compression solution is for NetFlash's all-flash FAS arrays. According to a blog posting by Adam Bergh, head of data center practice at Presidio, the program writes multiple IOs simultaneously to improve operational efficiency. From the WAFL space point of view, a 4KB block approach to IO consolidation does make more efficient use of resources. This chunk size is named WAFL ('write anywhere file layout' for ONTAP) and is devoted to disk writes. The mechanism uses 4KB data blocks to avoid waste of storage space. Specifically, the program will be a number of IO into a 4KB data block, and use this logic block to the actual write to disk. Each IO is included in a 4 KB logical block, even if its actual size is less than 4 KB. Through this compression process, 4KB logic blocks will continue to accommodate more IO until full load, and then create a new logical block to carry the next IO. This compression mechanism can work independently of deduplication and compression techniques, so the effects can be superimposed again. Can NetApp's 4KB block write technology really hold more data? NetApp ONTAP v9.0 compression principle diagram Bergh also talked about several other features in ONTAP 9. One is an enhanced analysis that will work with the upcoming OnCommand Performance Manager 3.0 and will introduce a headspace metric. The storage administrator can understand the usage of the ONTAP cluster model and use it as a basis for understanding the additional workload the node can carry. According to our understanding, it will monitor IO latency (in milliseconds per IO) and provide a percentage of utilization.
