13 HOME DASHBOARD Director VMAX - SG and Cache Response Utilization Time VMAX3 - SLO compliance 13

14 PA - MULTIPLE ARRAY DASHBOARD Quick indication that some Average components Link to IOs array and are running Throughput dashboard above their thresholds 14

15 PA - SINGLE ARRAY DASHBOARD UTILIZATION TAB Dashboard Tabs Q Depth Port Utilization Balance Utilization 15

16 PA HEATMAP HIGH LEVEL VIEW OF THE SYSTEM One engine Legend Cache / CP Disks by technology 16

18 PA - STORAGE GROUPS TAB EVENT CORRELATION SG Response Time alert Potential root cause Link to SG dashboard 18

19 PA USE CASE WALK THRU EVENT CORRELATION High Response Time Disks 2 nd threshold FE 1 st threshold 19

20 PA USE CASE WALK THRU IO PROFILE It s all READs The problem is not the backend and not in the cache. We should look at front end directors and ports. Large Reads It s all HITs 20

21 PA USE CASE WALK THRU STORAGE GROUP HEATMAP 21

22 PA USE CASE WALK THRU EXPAND HEATMAP FE directors look busy and queue depth utilization is red 22

23 PA USE CASE WALK THRU FE DIRECTOR DASHBOARD High Queue Depth Utilization Queue Depth is the problem. Add more FE directors to IO path, balance the work on the front end Each IO translates to ~2 requests 23

24 ROOT CAUSE ANALYSIS COMMON ISSUES AND BEST PRACTICES Configuration Balance Front end ports assignment Disks and disk pools Workload Your workload is different than what you think Contention Other applications compete on shared resources 24

25 CONFIGURATION FE / BE BALANCE WE HAVE DASHBOARDS FOR THIS All FE Dashboard Heatmap Balance Analyze - Diagnostics Front end dashboard Heatmap 25

30 AGENDA Unisphere Performance Analyzer Unisphere Database Analyzer 30

31 DATABASE STORAGE ANALYZER Database Storage Analyzer is part of Unisphere for Vmax (V8) Targeted for Oracle databases running on VMAX2 & VMAX3 Main goal: Helping customers to reduce time for performance troubleshooting 31

32 DSA DASHBOARD Identify DB with high IO response time IO breakdown to small and large 32

33 DB/STORAGE CORRELATION Unified view across DB & storage Look at the back-end activity for the Symm devices that are associated with the Database Compare DB and Storage response time Reduce troubleshooting time Identify DB bottlenecks that are not related to the storage Show the impact of FAST VP on DB performance 33

34 USE CASE 1: READ RESPONSE TIME STORAGE IS GOOD WHILE DB RESPONSE TIME IS HIGH High CPU load on the database server DB response time is 6ms Storage response time is 1ms 34

35 USE CASE 2: READ RESPONSE TIME BOTH DB AND STORAGE RESPONSE TIME ARE HIGH DB response time is ~12ms Storage response time is 9ms High activity on SATA drives 35

36 USE CASE 3: ANALYZING REDO WRITES DB response time is 4ms Storage response time is 0.5ms 36

37 ANALYTICS DEEP DIVE IO ANALYSIS I/O type: Random Vs Sequential Identify the Top I/O consumers in the Database 37

38 CORRELATING DB IOS TO DEVICES 38

39 A NEW DATABASE ENTITY IN U4V A New Database entity in Unisphere An A example new Database of the Utilization entity is created dashboard in for Unisphere the storage - components comprises of that the are associated database with devices the selected only database Storage Admin can view all the storage performance dashboards in the context of the database 39
