Sun has announced the release of Sun StorageTek HiCommand Tuning Manager v6.1, developed for Sun StorageTek 9990V, 9985V, 9990, and 9985, along with Sun StorEdge 9910, 9960, 9970, and 9980. This latest release includes revised platform versions, RAS improvements and general bug fixes.
Sun StorageTek 9900 Tuning Manager (HTnM) is part of the Sun StorageTek 9900 Storage Command Suite providing intelligent and proactive monitoring reporting and forecasting capabilities of Sun StorageTek 9900 storage resources, with a focus on business applications such as Oracle, DB2, MS Exchange and SQL. HTnM is also valued as a performance problem management solution when an application performance problem within the SAN needs to be tracked down to the storage array or some other component of the fabric.
New features and/or functions
- Windows 2008 support for RAID, Host, RAID Map and SQL Agents
- Red Hat Linux 4.6 and 5.2 support for Host, Oracle and DB2 Agents
- AIX 6.1 support for Host, RAID, Oracle and DB2 Agents
- SMI-S support for Switch Agent on Solaris OS for Brocade and Cisco switches
- AIX 5.3 LPAR/VIO support
- Solaris MPxIO support
- Oracle 11g support
Support for Windows 2000 is being dropped.
The forecasting and trending capabilities of HTnM will enable customers to potentially delay capital expenditures and budget for storage purchases more effectively. HTnM can present an accurate picture of the surveyed infrastructure with regard to applications, server and storage sub-system views.
Administrators will appreciate the productivity gains HTnM enables by allowing them to better manage their environment on a day-to-day basis, and to prevent capacity and performance crises by defining thresholds and alerts to avoid overrun situations.
The trend analysis capabilities of HTnM provide the ability to survey file systems and applications to determine storage needs more accurately and better allocate/provision storage. Trend analysis capabilities also help management in estimating future cost, margin or internal pricing considerations, and storage provisioning needs.
HTnM also enables improved application performance, improved SLA measurement, and the ability to troubleshoot performance bottlenecks.
Version 6.1 requires Sun StorageTek 9900 Device Manager software to be installed. If the customer does not already have Device Manager and appropriate software license, the Tuning Manager software distribution includes the necessary software components.
The specific information HTnM provides include over 150 standard history and forecast reports that can be customized, or new reports that can easily be created. The metrics fall within the following broad categories and most are available for real-time viewing, historical trending, forecasting and for troubleshooting. Below is the list of general categories with just some examples of the metrics available in each category:
average/minimum/maximum Read IOPS, Write IOPS, Read MB/sec and Write MB/sec transferred for total storage system, or for each storage port, or each disk parity group, or each logical device (LDEV), I/O response time within the array and cache capacity/% utilized, cache Write Pending and Sidefile utilization
capacity allocated and used, free, I/O queuing time, I/O service times, I/O's per second, I/O response time to/from the array, paging, swapping, memory used, % kernel mode, % user mode, wait time File Systems - capacity MBs/used MBs, capacity used %, free%, growth rate, Read IOPS, Write IOPS, Read MB/sec and Write MB/sec Device Files - average service time, average wait time, queue lengths, Read IOPS %, Write IOPS %, Read MBs/sec transferred, Write MBs/sec transferred
