Questions & Answers
What is SKU TK955AB - HPE XP7 High Availability Software 1TB 0-100TB LTU?
SKU TK955AB is a perpetual License‐To‐Use (LTU) enabling high availability features on HPE XP7 storage arrays with capacities from 0 to 100 TB, provisioned in 1 TB increments.
Which high availability features does this software provide?
It delivers synchronous replication, automatic failover, non-disruptive switchover, and multi-controller redundancy to ensure continuous data access and zero‐data‐loss protection.
What does '1TB 0-100TB LTU' designate?
'1TB' specifies the licensed capacity increment; '0-100TB' defines the supported array size range; 'LTU' indicates a perpetual, node-locked license for HPE XP7.
Which HPE XP7 array models are compatible?
It supports all HPE XP7 Series models—XP7640, XP8440, XP9440, and XP9840—within the 0–100 TB usable capacity range.
How do I install the high availability software?
Install via the HPE XP7 Service Console: import the license key, enable high availability options, then configure replication and failover policies through HPE Command View.
Can I upgrade if my capacity exceeds 100 TB?
Yes. Purchase additional LTU licenses in the next capacity tier (e.g., 100-200 TB) to scale high availability coverage beyond 100 TB.
How is the software licensed and billed?
Licensing is perpetual; you pay a one‐time fee per 1 TB increment. Optional support and subscription services are billed annually.
What support options are available?
HPE offers 24×7 Foundation Care, Proactive Care, and Personalized Care support plans covering software updates, hardware diagnostics, and rapid on-site response.
How does synchronous replication work on XP7?
It writes data to primary and secondary arrays simultaneously, ensuring zero recovery point objective (RPO) and seamless failover in case of a site failure.
What is the typical failover time?
Automated failover completes in under 30 seconds, minimizing application downtime and maintaining continuous data services.
Does it support multi‐site disaster recovery?
Yes. You can configure two or more XP7 arrays at remote sites for synchronous or asynchronous replication and orchestrated recovery testing.
How do I renew or extend the LTU?
Perpetual LTU licenses do not expire. To extend capacity, purchase additional 1 TB increments or higher‐tier LTUs; support contracts renew annually.
Is rolling software upgrade supported?
Yes. The software supports non‐disruptive rolling upgrades for controller firmware and high availability components without service interruption.
What performance impact can I expect?
High availability features introduce sub-millisecond latency overhead, ensuring enterprise-grade performance with full redundancy.
How do I monitor high availability status?
Use HPE Command View XP or the XP7 Service Console dashboards for real‐time health, replication status, failover events, and capacity utilization metrics.
Can I integrate with third-party backup tools?
Yes. The XP7 high availability software is compatible with leading backup and recovery solutions via standard SCSI/Fibre Channel protocols and snapshot APIs.
What are the prerequisites before installation?
Ensure your XP7 array firmware is at the required level, have free ports for replication links, and confirm network bandwidth aligns with your RPO requirements.
