CHAPTER 1 Introduction The Challenges Today, many businesses face ever-increasing challenges regarding reporting on, monitoring, configuring, and controlling their datacenters. Reporting Businesses are finding it difficult to keep track of what they have in their datacenters. For example, they need to know the number of storage arrays they have, the storage array vendors, how the storage arrays are being used, and by which applications.
Introduction The Solution The EMC Ionix ControlCenter 6.x family of storage management software provides an end-to-end solution for multivendor storage reporting, monitoring, configuration, and control. With Ionix ControlCenter, you can see the elements of your IT infrastructure (both hardware and software), know how your infrastructure is performing, and do what's necessary to ensure that service levels are met—for better performance, improved productivity, and reduced costs.
CHAPTER 2 Reporting on Your Datacenter EMC Ionix ControlCenter provides many solutions for creating detailed reports of your storage assets. Use these reports to keep track of what storage assets you have and what group or department is using them, monitoring storage capacity and utilization, planning for configuration changes to the datacenter, or identifying performance problems that can severely impact business operations.
Reporting on Your Datacenter Identifying IT assets for accounting This example demonstrates how a CTO can use EMC® Ionix™ StorageScope™ to create reports of the company’s IT assets, including arrays, hosts, and switches, for the corporate accountants. The CTO logs in to StorageScope, builds custom queries displaying all assets managed by Ionix ControlCenter, and prints them to a PDF. Once generated, the queries can be re-used to provide the information on demand.

Reviews the report to determine how much storage is available to hosts and host groups that use the application. Note: To prevent double-counting of storage resources shared by hosts within a group, the “Total” values in this report reflect the total storage capacity available to the group, not the sum of the storage available to each of the group’s hosts.
Reporting on Your Datacenter Charging departments for storage use The examples below demonstrates two different ways in which a CEO can track storage use by departments and charge them accordingly. Charging departments for storage resource usage For the purposes of this example, the enterprise’s storage resources (hosts, arrays, file systems and databases) are sorted into Ionix ControlCenter user-defined groups by the departments that use them.
Reporting on Your Datacenter • Chargeback.# File Systems • Chargeback.Accessible (KB) • Chargeback.Database Capacity (KB) • Chargeback.DB on Array (KB) • Chargeback.File System (KB) • Chargeback.FS on Array (KB) • Chargeback.Internal/JBOD (KB) Note: Refer to the StorageScope online help for full documentation of database fields used with the Query Builder. 6. In this example, no filtering is needed, so the DBA clicks Next to proceed to the Select Sorting, Grouping & Total Options step of the wizard. 7.
Reporting on Your Datacenter Figure 15 Host Chargeback report Charging departments for file group usage In the scenario shown below, the CTO creates a file group for chargeback for each department, and then adds the department’s file systems to the group. Then, the CTO runs the chargeback report to produce an itemized listing of each department’s file system storage use and chargeback amount. Creating file groups To create file groups, the CTO: 1.
Reporting on Your Datacenter 5. Clicks OK to create the file group. 6. Repeats this process for every file group being created. Adding paths to the file group After the file group has been created, paths must be added to it by the CTO, who: 1.

Because host l82ar155 was accessing the devices that share the same disk spindle on the Symmetrix array as host 182ar156, the competing workload caused the performance degradation. 76 EMC Ionix ControlCenter 6.
CHAPTER 3 Monitoring Your Datacenter EMC Ionix ControlCenter provides solutions for monitoring your storage assets. Ionix ControlCenter alerts notify you of problems (for example, a port is down, a disk is down, a volume is low on storage capacity) in the datacenter, while views such as Properties, Topology, Relationship, and Path Details allow you to investigate alerts and determine corrective action for addressing them.
Monitoring Your Datacenter Identifying and diagnosing loss of signal for a switch port This example demonstrates how a storage administrator uses Ionix ControlCenter to respond to a Loss of Signal alert for a switch port. In this example, a company has already defined a process for problem notification and resolution that allows the administrator to quickly identify, diagnose, and resolve the issue.
Monitoring Your Datacenter The alert indicates that the switch port is experiencing 10,303 signal losses within a 15-minute interval. (To determine the interval, the administrator right-clicks the alert and selects Alert > Details on the Actions tab or the Alert Definition dialog box, the schedule is every 15 minutes). This level of performance will severely affect communications between any devices that use the port. The storage administrator must take action immediately.
Monitoring Your Datacenter Figure 54 Acknowledge alert dialog box 2. Enters a note and clicks OK. In the Alerts view, the alert text changes from bold to plain text and the administrator’s ID appears in the Acknowledged By column.

Monitoring Your Datacenter Preventing a space shortage on a host logical volume In this example, the Windows administrator receives notification that a logical volume on a Windows host has reached a critical space threshold: 5 percent capacity remaining. The volume surpasses the threshold at 9 P.M., after the administrator has already left the office for the day.
Monitoring Your Datacenter Following the company’s procedures, the administrator first acknowledges the alert in the Alerts view to indicate that someone is addressing the issue. In the Alerts view, the administrator right-clicks the alert, selects Acknowledge Alert, enters a brief note in the dialog box, and clicks OK to close it. To diagnose the free space alert, the administrator: 1. Clicks the horizontal split-screen icon in the Alerts view to create a new view. 2.
Monitoring Your Datacenter A new Properties view opens below the Relationship view. The new view shows the volume size and the amount of free space available the last time the host’s Discovery data collection policy ran (Figure 65). Figure 65 Host file system Properties view According to the Last Modified column in the Properties view, the Discovery policy last ran just after midnight. At that time, the free space was about 6 percent, or 1.52 GB.
Monitoring Your Datacenter Locating additional free space Because the logical volume free space has fallen below the fatal threshold, the Windows administrator decides to act immediately and find additional free space. To find additional free space for the logical volume, the administrator: 1. Closes the Properties view. 2. Drags the top of the Relationship view up to better see the view’s contents. 3. Expands the Devices for l82ar154 folder.

To extend the logical volume, the administrator: 1. Right-clicks the logical volume and selects Allocation, Extend Logical Volume. 2. Completes a series of dialog boxes.
Monitoring Your Datacenter Fixing a disk transfer rate alert In this example, a senior Windows administrator receives notification about the performance of a disk on a vital Windows server. The alert is a Physical Disk Bottleneck (Transfer Rate) alert, which triggers when the transfer rate for a Windows disk exceeds a threshold. The senior administrator assigns the alert to a junior administrator to investigate. Assigning the alert To assign the alert, the senior administrator: 1.
Monitoring Your Datacenter 4. Clicks the Relationship button on the Console toolbar to change the new view type. 5. Drags the affected disk from the Alerts view to the Relationship view. The Relationship view maps the host device back to the Symmetrix physical disk on which it resides (Figure 67). Figure 67 Mapping a host device in the Relationship view 6. Drags the disk outside of the red box in which it resides and drops it in a blank area of the Relationship view.
Monitoring Your Datacenter Figure 68 Viewing Symmetrix disk relationships The junior administrator realizes that the host devices are likely contending for the physical disk cycles. So, the administrator reassigns the alert to the senior administrator and adds a note about the diagnosis. The senior administrator is likely to have to remap one of the host devices.
Monitoring Your Datacenter Automating the resolution to an Oracle tablespace space shortage In this example, a tablespace that belongs to the Sales database exceeds a threshold of 95 percent occupancy. The database administrator (DBA) identifies the problem by noticing an alert icon on the DBA folder in the tree. During the configuration phase, the DBA configured an autofix that would automatically trigger a script he had previously written to expand a tablespace.
Monitoring Your Datacenter 1. Expands the DBA folder and places a checkmark next to the folder in the tree to view the Properties of all the objects in the folder. 2. Follows the trail of arrows in the tree to discover which object has the alert. The DBA expands Databases, the sales database, and then Tablespaces. A red icon appears on the Sales object, indicating a critical or fatal alert (Figure 70).
Monitoring Your Datacenter Figure 71 Viewing the alert text A wrench icon appears in the Autofix column as a reminder that during configuration, an autofix was created to automatically expand a tablespace when it hits a critical threshold. The icon indicates that the autofix is currently running. While the DBA is reviewing the alert, the wrench icon changes; a green checkmark appears on top of it indicating that the autofix completed with a return code of zero (Figure 72).
Monitoring Your Datacenter Figure 73 Viewing Tablespace Properties Clearing the alert After confirming that the tablespace has sufficient storage space, the administrator notes the resolution for the problem, and then clears the alert from the Alerts view.

APPENDIX A About Virtual Provisioning EMC Ionix ControlCenter has extended it capabilites to perform Virtual Provisioning, also known as Thin Provisioning. This appendix discusses why datacenters should consider Virtual Provisioning, what it is, and how it works. This appendix contains the following information: ◆ ◆ Virtual Provisioning overview.......................................................................... 256 Virtual Provisioning glossary .......................................................
About Virtual Provisioning Virtual Provisioning overview Why Virtual Provisioning Businesses and organizations continually search for ways to both simplify storage management processes and improve storage capacity utilization. When provisioning storage for a new application, storage administrators must consider the application's future capacity requirements rather than simply its current requirements.
About Virtual Provisioning How Virtual Provisioning works Storage allocation operations are performed in thin device extents. A round-robin mechanism balances the allocation of data device extents across all of the data devices in the pool that are enabled and that have unused capacity. The initial bind of a thin device to a pool causes one thin device extent, or 12 tracks (768 KB), to be allocated per thin device.
About Virtual Provisioning Graphical representations of Virtual Provisioning are shown in Figure 234 and Figure 235. Figure 234 High-level representation of Virtual Provisioning 258 EMC Ionix ControlCenter 6.
About Virtual Provisioning Figure 235 Thin device relationship to storage pool devices Benefits of Virtual Provisioning and the role of Ionix ControlCenter Virtual Provisioning creates new benefits and new challenges for storage management. When managed properly, Virtual Provisioning can provide dynamic changes in how capacity utilization is managed and provisioned. Before Virtual Provisioning, metavolumes were used to stripe data over many physical disks.
About Virtual Provisioning Virtual Provisioning can improve storage capacity utilization and simplify storage management by presenting the application with sufficient capacity for an extended period of time, reducing the need to frequently provision new storage and avoiding the cost of allocated but unused storage.
About Virtual Provisioning Performance implications of Virtual Privisioning The performance implications for the use of thin devices depends on the nature of the workload and the state of the thin device. In a thin device implementation, there are response time and throughput overheads that are incurred the first time a write is performed on an unallocated region of a thin device.
About Virtual Provisioning Virtual Provisioning glossary High level terminology Virtual Provisioning EMC’s corporate term for thin provisioning. Storage Pool Umbrella term for storage pools used by virtual architectures. Commonly used terminology Thin Device Host accessible device that has no storage directly associated with it, referred to as a TDev. Device Logical unit of storage defined within an array. Data Device Internal device that provides storage capacity to be used by thin devices.
About Virtual Provisioning Thin pool terminology Thin Pool Total Capacity Total (writeable) size of the thin pool, excluding the overhead associated with RAID, mapping, binding, etc. Thin Pool Raw Capacity Total size of the thin pool, including the overhead associated with RAID, mapping, binding, and reserve capacity. Thin Pool Available Capacity Amount of storage in the thin pool that can be allocated. Thin Pool Allocated Capacity Amount of storage in the pool that has been allocated to thin devices.
About Virtual Provisioning Thin device terminology Thin Device Subscribed Capacity The size of the thin device, as seen by the host. Thin Device Allocated Reserve Capacity The amount of reserve storage that has been used by a thin device. Thin Device Allocated Capacity The capacity that has been withdrawn from the thin pool for the exclusive use of this thin device.
