Currently ten Seagate Exos 12TB disks are installed in RAID-6. Rough performance: Sustained sequential write is roughly 600MBps. Time to unzip linux-5.0 kernel source is roughly 24 seconds.<br /> <br /> The OS resides on two rear-facing 2.5&quot; Micron SSDs in RAID-1. Sustained write is 600MBps. Time to unzip linux-5.0 kernel source is ~6 seconds.<br /> <br /> Storage network connectivity is at 10Gbps; In tests, sustained sequential transfer over NFS4 to /vol ran at 500MBps (stripe size 32KB). We note that jumbo frames have not been enabled yet, and that the xfs stripe size is 128K. <br /> <br /> == Basics ==<br /> * SuperMicro SuperServer 3U body<br /> * 8x Xeon Silver 4112 @ 2.6GHz<br /> * 64GB RAM<br /> * Storage:<br /> ** OS: 2x480GB Micron 5200 in RAID-1<br /> ** /vol: 10xSeagate Exos 12TB in RAID-6 (95TB available)<br /> * Network<br /> ** Intel x722 10Gbps ethernet<br /> ** HMC<br /> * OS<br /> ** Centos 8<br /> ** Kernel 4.18.0-147<br /> <br /> == OS Configuration ==<br /> <br /> Mnemosyne has a standard CentOS 8 server install.</div>
