| Cluster maximum | n/a |
| Effective maximum | n/a |
| Data reduction | FCM4 compression; IBM claims up to 2x storage capacity in the same space with FCM4 but publishes no effective maximum |
| Protection | RAID 6, RAID 10 |
| Protection note | Host ports run FCP (open systems) or FICON/zHPF (IBM Z). Safeguarded Copy, Metro Mirror/Global Mirror, HyperSwap and GDPS are supported; IBM cites 2 s RPO and <60 s RTO at more than 1,000 miles. |
| Performance and connectivity | |
| Maximum IOPS | n/a |
| Maximum throughput | n/a |
| Latency | 16 µs |
| Conditions | Two IBM Power9+ processor complexes, 40 cores per system; cache options 1, 2 or 3.5 TB. Maximum physical capacity, flash cards and host ports are datasheet figures (with the E05 expansion frame). Latency is 16 us with zHyperLink; minimum response time without it is 80 us. Power is the peak electrical power of a fully equipped frame (Redbook table 5-5). IBM publishes no IOPS or throughput maxima. |
