1. Introduction
The EMC ViPR SRM solution enables you to identify and manage
the impact that storage resources have on the performance and availability of
your applications. You can assure storage services through end-to-end
analysis—from the application to the host and down to the storage array. With
improved insight, your storage resources will be optimized, resulting in better
cost control even while data grows at record rates.
The ViPR SRM provides you with real-time updates
through dynamic reporting of all resources and performance dependencies.
Furthermore, you can analyze application performance through trending and
threshold notifications correlated with storage metrics. You’ll gain a better
understanding of interdependencies through visualization of all physical and
virtual relationships—from the application to the host and from the host
through the storage—to improve efficiencies and optimize resources

2. Architecture
The ViPR SRM provides increased visibility into
heterogeneous storage environments. Its tight integration with EMC storage
systems enables customers to monitor and analyze their use of key EMC
differentiating technologies such as Fully Automated Storage Tiering for
Virtual Pools (FAST VP) and Federated Tiered Storage to meet both application
performance and cost containment objectives.
This new release of EMC ViPR SRM combines the functionality
of the three products, ProSphere, Storage Configuration Advisor and Watch4net,
into one product with a single architecture. While most customers welcome the
agentless discovery of the suite, some customers requested the option to deploy
agents. So now customers have a choice, agentless or agent discovery. Health,
threshold-based and configuration alerts have been consolidated into a single
report by severity as well as presented into a dashboard for at-a-glance
assessment of alerts by severity, device type and category. We’ve also added a
vApp-based deployment option in addition to the native OS install shield.
With the 3.1 release, the ViPR SRM now has a single
front-end portal and console, single database and single discovery/collection
engine. ViPR SRM provides a fully integrated solution of the individual
components that composed SRM Suite 2.0 (Watch4net, ProSphere and Storage
Configuration Advisor). The Suite enables a centralized view of a distributed
storage environment. It is focused on providing a view into what resources are
in use, how they are connected and if there are availability, performance or
capacity issues in the environment. It enables visualization, performance
troubleshooting, capacity reporting and configuration analysis.
3. Application to Infrastructure Mapping
ViPR
SRM provides end to end analysis that allows storage teams to understand and
visualize host to storage relationships and dependencies. There are several
topology view available: physical, logical masked and logical masked with
replicas. With these insights, you can analyze performance and availability
trends along the data path and how they may be impacting application service
levels
This
is an example of a custom dashboard that can easily be created to show the
host, VMware, SAN switch, host file system, storage and chargeback for an
application or business unit. ViPR SRM
will also show end-to-end views for environments that contain AIX-VIO, VPLEX,
and IBM SVC
4. Performance Trending and Reporting
When performance issues occur, the Storage Administrator
needs to identify or eliminate components within the storage infrastructure as
the cause of the problem. Identifying
the relationship dependencies along the data path is extremely difficult, which
only becomes more complicated in highly virtualized environments.
ViPR SRM offers detailed relationship views from the host to
the LUN with PowerPath metrics to analyze performance bottlenecks. This enables the Storage Administrator to
perform end to end analysis from the host to the switch to the array, identify
performance issues along the data path for traditional and software-defined
storage. It also includes centralized
PowerPath configuration, metrics and alerts for all PowerPath hosts to enhance
performance troubleshooting.
Automating key processes of identifying
end-to-end relationships, bottlenecks, and contributors to those bottlenecks
reduces the time it takes to troubleshoot performance issues from hours and
weeks to minutes and hours greatly improves Storage Administrators productivity 
ViPR SRM provides detailed end-to-end topology views for
your storage environment. It allows you to analyze performance from a virtual
or physical host, <CR> Hypervisor, <CR> switch, <CR> VPLEX
and <CR> array perspective. This
end-to-end visibility enables storage administrators to quickly isolate
performance problems across the data path. With ViPR SRM, you gain a visual
understanding of the complex relationships that exist in VPLEX environments
with the ability to quickly drill down and analyze performance anywhere along
the data path to improve service levels and increase productivity
You can analyze and report on performance trends for EMC and
third-party storage with ViPR SRM. This is an example report showing NetApp
Filer LUNs and Volume performance, Network and CPU performance. (Note: A complete list of all supported
arrays, switches, hosts and applications is available later in this deck.)
Understanding network usage by object storage
Organizations are increasingly adopting object storage to
support the development of mobile and web scale applications. These
applications demand high performance and drive the growth of unstructured
data. Understanding demands placed on
network capacity by rapidly growing
object storage environments is essential to ensuring consistent service levels
while supporting planning processes.
ViPR SRM automates reporting of network usage for EMC object
storage
ViPR SRM automates reporting of network usage over time
providing visibility into the total number of objects and data uploaded and
downloaded as well as visibility into objects read, objects written, data
downloaded, and data uploaded by project and service-level.
Automated analysis improves network capacity planning to
ensure SLA’s
With ViPR SRM’s automated reporting, storage
administrators gain insight into network utilization to improve capacity
planning processes. It also provides insight into data downloaded and uploaded
by project and service-level to align the cost of storage services with
workload requirements.5. Storage and Application Capacity Trending and Reporting
ViPR SRM’s reporting extends across data centers
sites and heterogeneous storage environments. It also has tight integration
with EMC arrays so you can define service levels based on FAST policy, VMAX3 Service
Level Objective (SLO), array model, or RAID type. It enables you to track the true cost of
supporting an application by allowing you to group hosts by application or
department and discover all capacity consumed by all primary volumes and
replicas supporting those hosts
ViPR
SRM provides storage teams with enterprise level storage capacity dashboards,
which includes EMC ECS, VMAX, DMX, VNX, VNXe3200, CLARiiON, Celerra, VPLEX,
XtremIO as well as multivendor storage from HDS, HP P9000, HP 3PAR, IBM XIV and
NetApp, enabling them to understand how much capacity they have and how much is
being used. Capacity utilization trends help identify when more capacity will
be needed.
Better
visibility into capacity utilization allows storage teams to more efficiently
manage that capacity which translates into more efficient use of capital. Automated report generation eliminates
tedious manual effort by storage teams, freeing them up to work on revenue
generating projects. Furthermore with
better insights to capacity utilization, they are now better armed to justify
new purchases.
6.Application Usage Chargeback
Storage Administrators need to ensure they are providing
show back or chargeback to application owners for all the storage that supports
the application. Capacity management is manual and error prone, making it very
time consuming and difficult to calculate the true cost of storage. Without
this visibility they cannot communicate the true cost of storage services to
application owners.
In this example, how would you charge for application
storage?
Local copies for backup should be charged to application
owner, not backup, despite mapping.
Local copy for development servers should probably be
charged to application as well
Remote copy should also be charged to the application since
it will be used in the event of an outage to recover the application remotely.
ViPR SRM provides chargeback reports which map storage to
service levels based on array characteristics or FAST policies. It has the
ability to track the consumption of capacity over time and identify the
application that is utilizing all the storage assets including primary storage,
snapshots as well as local and remote copies. This data is collected and can be
used in the formulation of a true chargeback report to the line of business.
Total chargeback for the application storage should include all this capacity.
Storage teams can provide application owners with chargeback
reports, enabling them to communicate the true value of storage services.
Automating these chargeback reports streamlines the reporting process to
application owners and improves the productivity of the storage team.
Experience
has shown that over half of SAN problems are due to configuration issues. For
most organizations, managing compliance with defined design best practices and
the support matrix guidelines is a manual and time-consuming process.
Non-compliance with defined policies can cause SLA violations which can take
hours/days to resolve. In some cases, penalties are paid for SLA violations.
ViPR SRM monitors compliance your design best practices and the EMC Support
Matrix to ensure your environment is properly configured to meet service level
requirements. Because configuration changes are tracked, you can investigate
changes that have been done over time to determine what change may have caused
an issue and eliminate hours of troubleshooting processes to improve productivity
Storage Administrators struggle to communicate the value and
delivery of storage services to a variety of users and roles. Reporting is typically manual and extremely
time consuming. ViPR SRM offers a
flexible reporting engine to create a wide variety of reports from the
extremely simple to highly customized.
Reports can be created and scheduled to run on a regular basis allowing
them to be easily shared or Emailed to key stakeholders such as application
owners, lines of business or tenants in the case of service providers.
Automating reports for key stakeholders saves
storage teams significant time and eliminates manual errors. With better reporting capabilities they are
able to communicate the value and performance of their storage services. These
are two examples of custom dashboards and reports that were created as part of
a sales campaign for a service provider in EMEA. The top dashboard was created for the storage
team who needs to view storage utilization across the platinum, gold, silver
and bronze storage tiers for all customers.
The bottom dashboard highlights the multi-tenant capability, which only
allows tenants to view their storage tiers
