Figure 1-5 IBM LinuxONE III four frame configuration. 1.3.2 Hardware configuration IBM LinuxONE III with 63 IFL, and 1.5 TB RAM IBM DS8886 with 512 GB of cache using two disks technologies The lab environment used the server and configurations as described in this section. The LPARs were defined in PR/SM using Shared IFL and had a sufficient weight to ensure  that all processors were configured in Vertical-High (both for z/VM and Native Linux). Using  Vertical-High processing allows the best performance for IBM LinuxONE processors. It  removes the constraint of having a dedicated processor, which makes changes on the LPAR  less dynamic. In this lab environment, the IFL processors were used with and without SMT2  to minimize the number of physical cores defined, while providing sufficient bandwidth for  applications with many threads. 8.5 TB HPFE (High-Performance Flash Enclosure) and 20 TB HDD (Hard Disk Drive SAS  600 GB 15k RPM) were used, depending on the data stored.  In this configuration, database disks (managed by Oracle ASM) were stored on HPFE and  Linux root file systems were stored on HDD. HDD was also used to store backups from the  system using IBM FlashCopyfi services. From a format perspective, RAID 5 was used for all  GLYPH<SM590000> 2 Native Linux LPAR for Oracle RAC database  GLYPH<SM590000> 1 LPAR hosting an Oracle WebLogic Server application server cluster  GLYPH<SM590000> 1 LPAR for z/VM, hosting 2 Linux guests for IBM MQ queue managers and Temenos lock  manager  On this server, 4 partitions (LPAR) had been defined as follows:  10  Temenos on IBM LinuxONE Best Practices Guide
