DDN | Into the enterprise AI mainstream by A3I solutions► The AI200 has up to 360TB of 24 x dualported NVMe flash drive capacity inside its 2U
enclosure, and hooks up to the DGX-1 witheither 4 x EDR InfiniBand (EDR IB) or
100Gbit/s Ethernet (100 GbitE). It delivers up
to 20GB/sec of file system sequential readthroughput and over 1 million IOPS.
► The larger AI7990, in a 4U cabinet, reverts
back to 20Gb/sec sequential read
performance and provides up to 700,000 IOPS.
It supports 90 x 3.5-inch slots for SSDs anddisk drives. There can be up to 4 expansion
chassis, each with 90 bays, providing up to5.0PB of usable capacity.

Example with 3 RAID 6 (8+2) pools
Rotating 8+2 parity across the Pool (or more correctly, across theVD, but here we have 1:1 VD:Pool)
RAID Pools has a RAID stripe size which is defined by the chunk size
– write one 8 chunks of data and 2 chunks of parity for each stripe

LUN(VD)

LUN(VD)2

RAID1

RAID6

Example with the same number of drives (31)Now we create a single DCR Pool across all 31 drives
The DCR creation divides all PDs into 8GiB PDEsThe formattable capacity appears lower than traditional
RAID as we include hot spare PDEs within the pool (at least
large enough to cope with a single drive failure)e.g. for 31x 8TiB drive we utilise 8TiB for spare PDEs

DDDDDP• Because one drive takes charge of all write processing whenrebuild does data using a hot spare drive, it becomes thebottleneck of the rebuild processing performance. Therefore,
Rebuild becomes it for a long time, and the risk of the Taro strikeincreases on the day by the simultaneous obstacle of pluraldrives. In addition, a performance decreases with becoming itfor a long time for long time of rebuild.
