9. Gigabit Ethernet

The 2100 supports 4 K and 8 K jumbo frame sizes, but only 4 K frames were tested in both JBOD and RAID1 modes. Figure 13 shows that jumbo frames help read performance approach the 100 Mbps Ethernet performance line, even though a Gigabit connection was in use.

Figure 14 shows write caching effects with 32 and 64 MB file sizes and also, once again, that jumbo frames provide a definite performance boost.
