What are Analysts saying….
"It's ironic that the largest, most sophisticated IT shops in the world are the ones most likely to have hidden problems."
"The issue is visibility - or the absolute lack of. We have no idea what issues we have, and where, most of the time. When you add virtual services into the infrastructure, you only compound the problem. It's like driving blind - you can wing it for a while, but sooner or later you will hit something."
- Steve Duplessie, Founder, Enterprise Strategy Group.

Solution: Remote Replication Availability
9/11. natural disasters, security concerns driving need for secure, remote site backup
Time to restore operations a major concern
Other tools provide little or no insight on impact of WAN performance on SAN operations
We can offer pre-install infrastructure assurance, post-install replication health check, and on-going replication assurance
29
Remote Replication Availability Solution
Pre-installation Remote Replication Infrastructure Provide a predictable process and shorten the time to production Verify the long distance connection is working in advance and meets the
planned capacity requirements Remote Replication Health Check Tune WAN expenditures to actual bandwidth consumption Capacity planning and usage Workflow versus bandwidth Verify replication goals (RPOs, RTOs)
Continuous Remote Replication Availability Detect Replication problems and slow downs before any data loss Verify compliance with DR policies (RPO, RTO)
30
Solution: Application Availability
Distributed storage systems and the growth of complex SANs make it hard to understand the factors determining application performance
Enterprise IT dislikes the finger-pointing between application, server and storage suppliers
By examining the conversations between SAN components, we can provide clear insight into application performance
31
Application Availability Solution
Pre-installation Application Infrastructure Availability Verify the infrastructure is working in advance and meets the planned
capacity requirements for the applicationApplication Traffic Analysis Verify traffic capacity used by the application Verify traffic is flowing according to failover policy and configuration Verify traffic is clean – no protocol error pollution from failing devices,
overrun queues, CRCs, etc.Continuous Application Availability Detect Application traffic slow downs before they impact the users Correlates application level workloads to actual SAN traffic Detect impacts to the application traffic after configuration, firmware or
hardware changes in the SAN Detect failing devices Trend the application traffic capacity Automated front-end for trace creation for hardware vendor problem

Pending Exchange Metrics for a ITL for the sampling interval for a channel (3 metrics)
Pending Exchanges: The number of exchanges that have been open, but not closed since both the probe and Portal have been monitoring a link. -1 indicates a reset occurred in this interval. -2 indicates that a valid link is not established so exchanges can not be determined.*Min number of exchanges open at once time during this interval.*Max number of exchanges open at once time during this interval.
SCSI Status Metrics for a ITL for a channel at a specific time (timestamp) during the sampling interval (3 metrics)
SCSI Status valueSCSI Sense code or 1 if noneSCSI Additional Sense Code or 1 is none
Pending Exchange Resets for a ITL
Event seen on the link which would result in the abortion of multiple pending exchanges. For example, if an initiator were to logout from a target, all pending exchanges between that initiator and target regardless of LUN should be reset to zero. The purpose of this is to tell the Portal to reset the pending exchanges for that particular initiator and target.
