The Sun ZFS Storage plug-in for Oracle Enterprise Manager Grid controller provides first-class monitoring to the grid controller environment for the Sun ZFS Storage appliance family with the ability to:Once an appliance is configured to be monitored by the grid controller, analytics worksheets and datasets are created to bridge the grid controller administrator's view to the deeper level of detail provided by the real-time analytics available within the appliance. The management plug-in is available at the following link: Oracle Technology NetworkIt is packaged with an installation guide that should be read by both administrators of the grid controller and storage administrators of appliances being monitored. Included with each appliance are two workflows that are used respectively to prepare a system for monitoring, or to remove the artifacts created for the monitoring environment:References:

For identifying performance issues, latency is essential. Paraphrasing performance expert Greg Brendan, latency is time spent waiting, and it has a direct impact on performance when caused by a synchronous process within an application request, thus making interpretation straightforward — the higher the latency, the worse the performance. This is in contrast to other metrics used in performance analysis — utilization, IOPS (I/O per second) and throughput — which are better suited for capacity planning and understanding the nature of workloads. References:

These are alerts based on the statistics from Analytics in Oracle ZFS Storage Appliance Analytics Guide . The following are properties when creating threshold alerts:Table 9-2 Threshold Alert Properties Property Description Threshold The threshold statistic is from Analytics in Oracle ZFS Storage Appliance Analytics Guide , and is self descriptive (e.g., "Protocol: NFSv4 operations per second")exceeds/falls below defines how the threshold value is compared to the current statistic Timing: for at leastDuration which the current statistic value must exceed/fall below the threshold only between/only during These properties may be set so that the threshold is only sent during certain times of day - such as business hours Repost alert every ... this condition persists. If enabled, this will re-execute the alert action (such as sending email) every set interval while the threshold breech exists Also post alert when this condition clears for at least... Send a followup alert if the threshold breech clears for at least the set interval The "Add Threshold Alert" dialog has been organized so that it can be read as though it is a paragraph describing the alert. The default reads:References:

The rich set of data services and appliance options further enhance the economic benefits of the Oracle ZFS Storage Appliance. All protocols (such as Common Internet File System (CIFS), Internet Small Computer System Interface (iSCSI), InfiniBand (IB), and Fibre Channel (FC) and others) are included in the base price of the system. Various data protection options and several data compression options are included in the base price. Customers can choose between high-capacity and high-performance SAS disk drives and various memory (DRAM and flash) options to optimize for their performance and capacity needs while staying within budget. Advanced data services like remote replication and snapshot cloning are also available. References:

Verification and Allocation The verificationphase allows you to verify that all storage is attached and functioning, and allocatesdisks within chassis. In a standalone system, this presents a list of all available storage and drive types, with the ability to change the number of disks to allocate to the new pool. By default, the maximum number of disks are allocated, but this number can be reduced in anticipation of creating multiple pools. In an expandable system, JBODs are displayed in a list along with the head node, and allocation can be controlled within each JBOD. For each JBOD, the system must import available disks, aprocess that can take a significant amount of time depending the number and configuration of JBODs. Disks within the system chassis can be allocated individually (as with cache devices), but JBODs must be allocated as either 'whole' or 'half'. In general, whole JBODs are the preferred unit for managing storage, but half JBODs can be used where storage needs are small, or where NSPF is needed in a smaller configuration. References:

Data is triply mirrored, yielding a very highly reliable and high-performing system (for example, storage for a critical database). This configuration is intended for situations in which maximum performance and availability are required. Compared with a two-way mirror, a three-way mirror adds additional IOPS per stored block and higher level protection against failures. Note: A controller without expansion storage should not be configured with triple mirroring.References:
