Hi Denver, its like christian said. On top of that, i would add, that iSCSI is always a more native protocol. You dont have to go through as much layers as you have it -per design- with a software defined storage. So you can expect always a better performance with hardware accelerated iSCSI. If you are looking for a cost efficient solution, take ceph. If you have the money for this HP stuff, and if you are sure, your needs will never grow over this (199) SFF-SAS/MDL SAS/SSD or 96 LFF SAS/MDL SAS Disklimit, then take this HP stuff. ---- Another decision making reason: For sure, taking this HP stuff means, taking a solution which will natively work with everything ( iSCSI ). Also you will have commercial support with you ( if you buy them new / with support package ). So, if you are not familar with ceph, and want to run important data/services with your storage, maybe you should pick a solution which will have vendor support and a less "configure all yourself" solution. The upside of that is of course, that you have a limited amount of possibilities to kill your services yourself. The downside is, that you have a very limited amount of possibilities to tweak and also debug your services. If it works, fine. If not you might end up being forced to wait for the vendor support and just hope they will react fast and solve your case. While with a commercial product like this, usually the UI/utils/management possibilities are usually well grown. So maybe your chance that something is going wrong might be not too much big. But if something is going wrong, you can just wait for help. While with ceph and linux you usually have always the chance to debug/do something yourself ( IF you have the knowledge ). If not, and if you dont have time to learn that knowledge, taking ceph, or any other system you dont know, but having productive data on it, is just a BIG invitation for murphy to give your life a nice kick :) ----- So, as usual: Eighter you have the knowledge yourself and be able to 1. save money 2. debug stuff yourself Or you pay someone else to have it, and this way, if you picked the right partner, being on a safe(er) side that things will not go mess. -- Mit freundlichen Gruessen / Best regards Oliver Dzombic IP-Interactive mailto:info@xxxxxxxxxxxxxxxxx Anschrift: IP Interactive UG ( haftungsbeschraenkt ) Zum Sonnenberg 1-3 63571 Gelnhausen HRB 93402 beim Amtsgericht Hanau Geschäftsführung: Oliver Dzombic Steuer Nr.: 35 236 3622 1 UST ID: DE274086107 Am 22.06.2016 um 01:09 schrieb Denver Williams: > HP MSA 2040 10GBe _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
