Data Centre Applications
iSCSI Hosts & Storage
Mission-critical applications in high-end data centre environments often require
higher aggregate throughput and are more sensitive to latency. Because of the
high throughput demand, iSCSI HBAs will eventually find their largest market
in these environments. However, some mission-critical applications might
remain on FC systems until iSCSI performance improves even further, such as
when 10GbE is widely available.
In the meantime, companies are starting to deploy a mix of FC and iSCSI
hosts in the data centre. iSCSI can be used on mid-range servers that don’t
require high levels of throughput and don’t have high CPU utilization.
The central SAN can also be extended to satellite locations using iSCSI. iSCSI
allows remote offices to access FC storage in the data centre.
