I am currently using a
Dell R720 with 256GB Ram
(Write Drives) I combine 4 x ( raidz2 with 4 wide 14TB UltraStar 7200RPM drives.) If I did the math correctly it's about 255 MB/Sec per pool x 4.
2 10gb nic Lagg.
(Backup Drives) I combine 4 x (raidz2 with 11 wide 14TB UltraStar 7200RPM drives.)
I am looking to record about 200 IP cameras at 5-10 mbps per camera. I am worried about the iops. Will adding an SSD or NMVE Slog to the write or backup drives help with security cameras?
I am also worried about losing a pool. What if the front half of the jbod loses power or connection will this distory the pool if half the drives are located in the back?
How do I keep the DA numbers the same? Seems like the order gets mixed up.
