Share a brief history of your project and organization

The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) is a Chinese national scientific research facility operated by the National Astronomical Observatories, Chinese Academy of Sciences. It is a special reflecting Schmidt telescope with 4000 fibers in a field of view of 20 deg2 in the sky. Until July 2019, LAMOST has completed its pilot survey, which was launched in October 2011 and ended in June 2012, and the regular survey of the first seven years, which was initiated on September 2012[1-7]. In this data release, there are totally 10,431,197 low resolution spectra published, which satisfy the selection criteria that the LAMOST LRS General Catalog also used. The data products of this release can be available from the website http://dr10.lamost.org/v2.0/.

Guoshoujing Telescope (the Large Sky Area Multi-Object Fiber Spectroscopic Telescope LAMOST) is a National Major Scientific Project built by the Chinese Academy of Sciences. Funding for the project has been provided by the National Development and Reform Commission. LAMOST is operated and managed by the National Astronomical Observatories, Chinese Academy of Sciences.

Thanks for the patience of the allocator's review, first of all allow me to briefly introduce myself, I'm Fengfei, a filecoin lover, the earliest contact with filecoin is because I purchased a filecoin miner in 2021, with the attention of the time lapse, I gradually know a lot of eco-partners, such as Ehume, Genesis, and at the same time, my good partner @winter0707winter has been also for the ecological efforts to store educational data in the filecoin network. Inspired by him, I familiarized myself with all the filecoin workflows and I am now a full-fledged filecoin participant.

Introduced by my eco-partner, I am currently in ongoing communication mainly with the following SPs: f03178144, f03179572, f03214937, f03229932, f03229933, f03231117,f03055018, f03055029, f03231121, f03151449, f03151456, f03179570, f03179555, f03178077, f01106668, f01315096, f0870558, f03055005,, f01518369, f01889668 , most of the SPs have prepared 70-90% of the pledged coins, as a data preparer, I mainly prepare data through official tools such as boost, lotus, Singularity, etc., I noticed that throughout the filecoin network, LAMOST DR5-DR7 have been stored by many SPs, but LAMOST DR10 are hardly stored.

The uncompressed data size of each spectral data is = 205MByte.

Originally we planned to save 8 replicas to different SPs.205MB （11441011+8259362） Spectra /32GB per sector 8 replicas = 985980.582 sectors = 30 PiB DataCap

According to the formula, a total of 30 PiB Datacap can actually be applied for, with 8 backups, each data piece having 3.75 PiB. However, considering the initial application, we will prepare 2.5 PiB for each data piece, totaling 20 PiB for the application.

As a first round, I hope to get support from reviewers. Thank you very much, I will do the good distribution and look forward to the surprising report.

spaceT9 commented 1 day ago

Checked most of the LAMOST series data on the filecoin network, and DR5-DR7 are indeed being stored in large amount as you said.

Looks like also an old ecosystem participant of the filecoin community, willing to support 1 PiB as the first round following distribution rules.
