Migrate To Emc Symmetrix Vmax Eng

  1. 1. Evaluation of the results carry heavily database servers on the storage system (SAN) EMC Symmetrix VMAX<br />===><br />Korol Oleg, Head of Network Team, 2011<br />
  2. 2. Scheduled to migrate data (5 servers) located at a number of EOS/EOL storages – 2xIBM DS4100, IBM DS4800<br />Configuration of IBM DS4100<br /> 14хHDD 400GB SATA (each)<br />Configuration of IBM DS4800dual-controller 1815-82A<br />14хEXP810<br />224xHDD different models 73GB 15K 4Gb FC/ 146GB 10K 2Gb FC/ 146GB 15K 4Gb FC<br /> (6 of them HotSpare)<br /> 120xHDD used to accommodate the most "severe" DBMS ABS B2 andDWH<br />the remaining available 98хHDD used to accommodate data from 32 servers who have not participated in the migration to new storage<br />Configuration of EMC Symmetrix VMAX<br /> 1xVMAX engine<br /> 200xHDD 300GB 15K 4Gb FC<br /> 9xEFD 200GB<br /> (8xHDD и 1хEFDHotSpare)<br />*EFD – Enterprise Flash Drive (SSD)<br />Migrating data on storage EMC Symmetrix VMAX<br />2<br />
  3. 3. Previously held a series of tests to determine the characteristics of both SSD performance when using R5 and VMAX in general<br />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) <br />Synthetic test, 100% Random, R/W = 80/20<br />Migrating data on storage EMC Symmetrix VMAX<br />3<br />
  4. 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<br />This screenshot is presented disk performance is productive database, which confirmed the results of previously conducted synthetic tests SSD<br />438.4K/27.4K= average 16KB block size<br />Migrating data on storage EMC Symmetrix VMAX<br />4<br />
  5. 5. DWH (Oracle 10, OLAP), Disks Latency in msec, less - is better16x times less latency<br />Before (IBM DS4800)<br />After (EMC VMAX)<br />Migrating data on storage EMC Symmetrix VMAX<br />5<br />
