Probably around a decade ago, =24DAYJOB at the time was ap= proached by a vendor who had a very compelling and cost-effective erasure-coded st= orage product that would have allowed us to have the data at 3 sites, and total= loss of any one would be survivable. Two sites were about 3 cable miles apart= , and the third was 95 cable miles and could only run at 10Gig speed back then.= And what sank the deal was uncertainty if we could meet throughput requir= ements under heavy load with one site that distant. (You'd be *amazed* what hap= pens in the first 3 minutes after semester add/drop goes live at midnight, whe= n you have 35,000 students. :) The other great bugaboo - How do you back up a half billion files that to= tal 12+ petabytes? (It doesn't help the solution space when the majority of i= t is one research group that (a) will probably eventually data-mine their data= for =24100M+ in research grants and also (b) the terms of some of the grants specified a 30 year retention on the data *and* some wicked nasty PII is= sues, because the data includes identifiable video of people who had not consen= ted to be part of the research study... Storage - it turns out you can't just throw 10 terabyte drives at the pro= blem. :) --==_Exmh_1589009682_4501P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Comment: Exmh version 2.9.0 11/07/2018 iQIVAwUBXrZdEQdmEQWDXROgAQICiw//dPBWvpZ6cfe2CbF689LshPq+H76MQhsS sRsHN3EbMOtpw267q1DV27cxBoz6qkhKIvFsinSa5KsqmU/1CKl0plJwVch+BMLP arZIWooairyFF9KFYeUoHkqd1ikmIrW79+HA+TTsVahG0Ay5nMw1fooGKIBIOryx 3gBUKEQ1pRz88jZDTp5S3/I6dHObURImASMGPP8BTeisSQTR+TIf8XKt8nxEbwn4 u+TK7dhGJIim+fi7AjqCseqhgNh/MSayYRtMPgF3dYYrIYTjssTvTuXNwpdGmCIF vqARqbHYqwZ3L4toR32aEjyNVOmq02UIV6sQajrMFQsbI9IFpeMuwyYbn704lnCz kM5lEXn9zcYqsxcSRHRbmGVoaxYgtmLJ/XEBQiooWEIcHToBBSQqhbGc7t46KE7F 9Jc+hZtxThOZJ+eSNAgApiV3PofsULq4loyqIkRZod7HpguoMReZfi0Wrzbk981U aw/w/Lkjlgt6v1ljw34pga4oePcxqoJMLfpfZvcZrW5HNYulxG+BviyasVaSqG9Q KAk8xzrdt0/scvNiB7bQ+qh9l+T3rGJXvCo90cuwUp0yAF0TL4dfvDpLDWvH4p+b QArPbt7zSf3ETdeGWF0DzSAEDRaTTVB6YckakY6Qg9gwWnruRV9WJeyG05GyAN/1 kyM5Zd6fpM8= =zlv7 -----END PGP SIGNATURE----- --==_Exmh_1589009682_4501P--
