1. Evaluation of the results carry heavily database servers on the storage system (SAN) EMC Symmetrix VMAX ===> Korol Oleg, Head of Network Team, 2011

2. Scheduled to migrate data (5 servers) located at a number of EOS/EOL storages – 2xIBM DS4100, IBM DS4800 Configuration of IBM DS4100 14хHDD 400GB SATA (each) Configuration of IBM DS4800dual-controller 1815-82A 14хEXP810 224xHDD different models 73GB 15K 4Gb FC/ 146GB 10K 2Gb FC/ 146GB 15K 4Gb FC (6 of them HotSpare) 120xHDD used to accommodate the most "severe" DBMS ABS B2 andDWH the remaining available 98хHDD used to accommodate data from 32 servers who have not participated in the migration to new storage Configuration of EMC Symmetrix VMAX 1xVMAX engine 200xHDD 300GB 15K 4Gb FC 9xEFD 200GB (8xHDD и 1хEFDHotSpare) *EFD – Enterprise Flash Drive (SSD) Migrating data on storage EMC Symmetrix VMAX 2

3. Previously held a series of tests to determine the characteristics of both SSD performance when using R5 and VMAX in general We used the following test configurationsIBM DS48004xR1(5+5) 15K 144GB FC2/4EMC V-MAX4 metas (total 48 H-Vols, protection 2M)EMC V-MAX2LUNs fromSSD-pool, protection R5 (3+1) Synthetic test, 100% Random, R/W = 80/20 Migrating data on storage EMC Symmetrix VMAX 3

4. for DWH hot tablespaces (60% of all readings in the database is in the region less than 10%) were submitted to separate LUN, located on the SSD This screenshot is presented disk performance is productive database, which confirmed the results of previously conducted synthetic tests SSD 438.4K/27.4K= average 16KB block size Migrating data on storage EMC Symmetrix VMAX 4

5. DWH (Oracle 10, OLAP), Disks Latency in msec, less - is better16x times less latency Before (IBM DS4800) After (EMC VMAX) Migrating data on storage EMC Symmetrix VMAX 5

6. DWH (Oracle 10, OLAP), Disks Performance iops/MBps, more - is better1.5x more MBps and 4.5x more iops Before (IBM DS4800) After (EMC VMAX) Migrating data on storage EMC Symmetrix VMAX 6

7. ABS (Oracle 10, OLTP/OLAP), Disks Latency in msec, less - is better Before (IBM DS4800) After (EMC VMAX) Migrating data on storage EMC Symmetrix VMAX 7

8. ABS (Oracle 10, OLTP/OLAP), Disks Performance iops/MBps, more - is better Before (IBM DS4800) After (EMC VMAX) Migrating data on storage EMC Symmetrix VMAX 8

9. Overall Disks Performance iops/MBps 5 servers after migrate then to EMC VMAX Migrating data on storage EMC Symmetrix VMAX 9

10. Annex All hosts running on IBM Power under AIX 5.3 To conduct synthetic tests have been used ndisk64, from the package nstress For data collection tool used NMON For processing and visualization of statistical data used NMON Analyser and NMON Consolidator Questions?
