SAN Monitoring BMC and Sentry solution to detect faults, proactively monitor the performance and capacity of a multi-vendor SAN environment

Agenda Getting started Use cases Products Features Overview Supported Devices Architecture Use cases Detecting a hardware failure Failed disk Broken link Identifying the bottleneck in the SAN Traffic on the SAN Disk array overall activity Controllers Cache LUNs Physical disks Search for a WWN Monitoring the available storage capacity Hardware inventory Reporting on the disk allocation in a SAN Thin provisioning Reclaiming unused space Filesystems in a filer

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

Detecting Hardware Failures

Detecting Hardware Failures

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

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.

Monitoring the Traffic on the SAN

Monitoring the Traffic on the SAN

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

Identifying the Bottleneck in the SAN

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

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-F004-329D-2301 Search WWN utility Benefits Reduce time to deal with SAN issues

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

Reporting on the Disk Allocation in a SAN

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

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.
