+ | ===== Spectrum Protect Server block size considerations ===== | ||
+ | |||
+ | DB block size used: 8kb\\ | ||
+ | Storage pool DISK and FILE: reads and writes to storage pools predominantly in **256 KB** blocks\\ | ||
+ | The extents can range in size from 50 KB to 4 MB with an average of 256 KB. Any data smaller than 2 KB or data that cannot be deduplicated, such as encrypted or compressed, are not deduplicated. | ||
+ | |||
+ | S3: By default, these files are 1 GB in size and are configurable using the parameter | ||
+ | CloudTransferContainerSize server option (i.e. specifying in dsmserv.opt or using the “setopt” server command). These files are transferred to Access using S3 multipart-upload. With 1 GB default file size, the default part size that the file is broken up to is 100 MB. | ||
+ | This value is configurable using the server parameter, CloudMinUploadPartSize. For restores, IBM Spectrum Protect does range reads in smaller sizes of 10 KB – 100KB | ||
