6. Architecture – Monitoring Hitachi

7. Detecting Hardware Failures
Hardware Monitoring module
Same module for all disk arrays, SAN switches and tape libraries
Brocade, Cisco, Dell, EMC, Hitachi, HP, IBM, NetApp, Quantum, StorageTek, etc.
Same classes and parameters  Easy integration
Same module for the servers!
Comprehensive
Temperature sensors, fans, power supplies, controllers, network cards, fiber ports, disks, HBAs, tape drives, etc.
Robust
Polls the status of each component (not event-driven)
Versatile
SNMP, WBEM, Telnet, SSH, command lines

8. Detecting Hardware Failures

9. Detecting Hardware Failures

10. Detecting a Hardware Failure
Upon hardware failure, a standard alert is generated
Natively integrates with BEM, ProactiveNet or 3rd-parties
The alert contains a full text description of the problem
Short description, status reported by the device
Value of the various parameters and thresholds
Possible consequences and recommended action
Help to identify and replace the faulty device
Key Benefits
Reduce costly downtime
Reduce MTTR hardware failures

11. Monitoring the Traffic on a SAN
Monitoring done from the fiber switch
For each port
Status of the SFP
Link speed and status
Received and transmitted packets, error percentage
Traffic (received and transmitted)
Bandwidth utilization
Reporting
MB/sec
Total amount of data in GB per day
Benefits
Identify big users (servers)
Analyze the impact of the nightly backups, the mirroring
Analyze the impact of the deployment of a new application
Diagnose multi-pathing issues
Identify disk arrays under hard pressure
Etc.

12. Monitoring the Traffic on the SAN

13. Monitoring the Traffic on the SAN

14. Identifying the Bottleneck in the SAN
Monitor the traffic on the SAN
From the SAN switch point of view
I/Os for each port, in MB/sec and GB per day
Monitor the I/Os at each level of the disk array
Overall traffic
Each controller
Each LUN
Each physical disk
MB/sec and GB per day
Additional metrics like: Response Time, % Time Utilization, Request Rate, Cache
Diagnose unbalanced workload
Compare the traffic and % Time Utilization on each controller
Compare the traffic on each physical disk
Check the LUNs owner controllers

15. Identifying the Bottleneck in the SAN

16. Identifying the Bottleneck in the SAN
Key Benefits
Reduce time to diagnose performance issues
Avoid costly and unnecessary upgrades
Arbitrate issues with a centralized view of servers and SAN performance

17. Identify a WWN Every component on the SAN is identified with a WWN
Ports
Nodes
Storage groups
LUNs
Cumbersome for administrators to deal with WWNs
Look like 100A-F D-2301
Search WWN utility
Benefits
Reduce time to deal with SAN issues

18. Reporting on the disk allocation in a SAN
Hardware inventory
Disk space reports
At the physical level (“primordial storage pool”)
At the storage pool level (RAID sets)
Overall
Size of the disk array
Amount of disk space brought online
Unallocated space
For the entire SAN
Thin provisioning
Support in vendor-specific modules
Host-visible Capacity vs Allocated vs Reserved
Critical to monitor the utilization to avoid SAN-wide crash

19. Reporting on the Disk Allocation in a SAN

20. Reclaiming Unused Disk Space
Decommissioned servers often leave orphan LUNs
Tool to list the LUN mapping table
Unmapped LUNs can be deleted
Benefit
Optimize Space Utilization
Avoid costly and unnecessary upgrades

21. Sentry’s Hardware and Storage Monitoring Solution
Why BMC and Sentry
Goal
Improve uptime, optimize performance
Lower IT costs
Manage energy costs
Where it Hurts
Missed hardware failures
Long time to resolve problems
Hardware-related problems
SAN-related problems
Problems involve sysadmins, network admins and SAN admins.
Hard to arbitrate
Integrating the monitoring of a new platform is complex and time-consuming
Energy expenses keep climbing every year
Frustrating not to know the culprits and what to do about it
Root Cause
Lack of visibility on server and SAN hardware health
Lack of visibility on SAN perf.
Hardware instrumentation is vendor-specific and sometimes even lacking
No per-device visibility on power consumption
Solved by
Sentry’s Hardware and Storage Monitoring Solution
How
Monitors the hardware
Servers, disk arrays, SAN switches, tape libraries
Disks, RAIDs, power supplies, NICs, HBAs, processors, etc.
Discovery, Inventory, Monitoring, Diagnosis, Reporting, Data traffic monitoring
Single solution for all
Brocade, Cisco, DELL, EMC, Fujitsu, Hitachi, HP, IBM, NetApp, Sun, etc.
Monitors the power consumption
On each server and SAN device, in Watts and kWh
Works on 100% of IT
Really?
IBM (outsourcing) chose BMC+Sentry over their own solutions (Tivoli and Director) to make sure they meet their customer’s SLA criteria
DELL chose Sentry to integrate their own “OpenManage” solution with BPM, BEM, etc.
