First exadata box V1 released in 2008 with the combination of Oracle software and HP hardware. Since that time Oracle came up with multiple exadata version with improved hardware and software. 

Oracle Exadata X6-2 released in Arpil-2016 which is the 7th generation of exadata. Since 2008 its first release V1, exadata gone under a number of significant changes in terms of resource performance and capacity. 

You can go through our earlier post for more detailed history of Exadata.

7 Things You Should Know About Exadata X5-2

Following are the major differences or features of Exadata Machine X5-2 compare to X4-2 machine.

• Solaris operating system is not supported on ED X5 anymore
• ED X5 supports OVM 
• High performance configuration has been replaced by Extreme Flash
• Each extreme flash storage contains 8 x 1.6 TB PCI flash drives
• Disk controller battery eliminated for flash card
• CPU increased to 288 cores per full rack, 2 x 18 core per Database server
• Memory can be upgraded up to 768 GB per database server

Comparison between Exadata X4-2 and X5-2

Obliviously ED X5 would be faster and flexible compare to earlier version of ED. Here we have given comparison between X5 and X4 full configuration ED rack based on datasheet provided by Oracle.

Now from X5-2 Oracle introduced Oracle Virtual Machine to do the virtualization on ED machine, if there is any requirement of hard limits on CPUs and memory or required independent OS/Admin than we can use this virtualization feature.

There is no licence cost for OVM , it's free of cost with ED X5-2.

From ED X5-2 High performance disk has been replaced with Extream Flash (EF).
