Description: Storage as a Service (StaaS) is a SLAC shared file service operated by the Office of the CIO (OCIOScientific Computing Services (SCS) within the OCIO division of Business and Technology Services (BTS).  It is designed for groups who need approximately 5TB to 75TB of shared UNIX Unix storage .  It and is currently targeted at moderate science workloads and larger average file sizes rather than hundreds of batch jobs and millions of small files (see quota information below).  Access is available via NFS (versions 2 through 4) and or an optional GPFS client, and is currently limited to the SLAC network.

Pricing: US$65 per terabyte per year during FY19 (10/1/2018 through 9/30/2019), with at least a 1-year commitment.  The charge is based on disk allocation rather than disk usage and has a minimum requirement (see quota information below).  Charges accumulate daily (to allow for mid-year adjustments in allocation) while billing is done quarterly in arrears.  This means your October through December allocation is billed in January, January through March is billed in April, and so forth.  The last billing may occur in September to accommodate the end of each fiscal year.  Pricing is reviewed before each new fiscal year, with an intent to keep it as low possible and stable throughout the following year.

Quotas: The minimum starting disk quota is 5TB; the maximum will vary according to available disk space.  As long as you maintain the minimum level, your disk quota may be increased or decreased in terabyte increments when needed, with rates being prorated from the date of change.  The default inode (file and directory) quota is 1 million inodes per terabyte, which allows for an average file size of 1MB.  A reasonably higher inode quota is available for free upon request to allow for a smaller average file size.
