This blog is part of a series on what’s new with clustered Data ONTAP 8.3. This blog focuses on performance improvements. Compared to clustered Data ONTAP 8.2, there are significant increases in read performance with clustered Data ONTAP 8.3. As indicated in Figure 1, the FAS8080 EX offers leading OLTP performance. The all-flash FAS8080 EX running clustered Data ONTAP 8.3 offers 360K IOPS with ~1ms latency providing best-in-class integration with database applications, rich data management capabilities and enterprise-proven availability and non-disruptive operations.
Upgrading an all-flash FAS system from 8.2.x to 8.3 can deliver a performance improvement of up to almost 70% with no hardware changes-and all-flash FAS performance was already highly competitive before 8.3.

In addition, Flash Pool cache sizes have increased by 4x as shown in table 1 from 8.2.2 to 8.3 for the FAS2500 and FAS8000 systems, as well as older FAS2200, FAS3200 and FAS6200 systems. The cache size increase improves throughput and decreases response times.
