First of all, check https://premier.dell.be. For storage servers, check http://www.serverdirect.nl (sto3/4 were ordered there). Supermicro are really good for storage, and support at serverdirect is quite good. e.g if you order a server for storage, zfs will be the preferred file system (used in sto1/2/3/4), so you don't need expensive RAID controllers but just HBA cards to connect the HD's (SAS). At serverdirect they will already configure this host card , so you just have to plugin the HD's. Keep in mind you need a lot of memory when configuring a ZFS storage server. The latest webserver (visiesrv2) comes from dell. see order_be_rel_publ_223134746_2017-11-08.pdf
