HP Public Cloud Release Notes

This page contains the following information on our software package:

New and updated in version 13.5

New look and feel for the Management Console - Based on the OpenStack Horizon project, the new HP Public Cloud Console interface and user experience is significantly improved from the original classic management console. This new user interface provides you with project dashboards that display group-related services for easier availability and service management. Documentation is provided in-line and embedded throughout the console on many forms, reducing your clicks and improving your console experience. Although workflows may look different, you can still manage your standard functions through the console, including initializing instances, creating volumes, launching images and snapshots, and creating security groups and key pairs. See Getting Started with HP Public Cloud Console for more information.

Larger compute instances for big data and high-performance computing - New larger instance types allow you to run big data, analytics, and high performance computing (HPC) workloads in the public cloud. You can access instances with up to 120 GB of RAM and up to 16 virtual cores. The new instance types allow even greater flexibility to choose the virtual machine size that best fits your application's compute resource needs.

New virtual private cloud (VPC) networking capabilities - The new VPC functionality provides the ability to deploy your workloads with even greater security within the public cloud for hybrid delivery or public cloud only by enabling you to create isolated virtual networks within the HP Cloud compute service. UsingSoftware Defined Networking (SDN), VPC allows you to create a wide variety of network configurations specific to your individual workloads needs with a variety of public Internet accessibility options. You can also connect your public cloud network to your on-premise network, enabling true hybrid delivery through private and public infrastructures with a secure VPN connection performing as a single integrated system.

Networking topology visualization - The new Horizon-based public cloud console inherits network topology infographics. In addition to visualizing network relationships, you can perform dynamic network management, interactively creating networks and routers, and launching instances through a 2-D visualization scene.

Faster data upload to the Cloud - A new bulk import service reduces the time to market for applications requiring existing data by allowing you to quickly and easily load your data into HP Public Cloud block storage or object storage. The new service bypasses the process of transferring large amounts of information over the Internet and allows you to provide hard drives directly to HP's data centers where your data can be rapidly transferred.

More object storage options - HP Public Cloud Console users can now setup and control object storage container synchronization across multiple regions. Cross-region replication contributes to a more achievable business continuity plan for disaster recovery options which are often at the forefront of most enterprise organizations priorities. Public Cloud Console users also have the ability to store duplicate versions of content within these storage containers, to restore from unintended failures or deletions, or for the purpose of data archiving, among others.

Larger file size transfers via the CLI - You can now use the Windows CLI to transfer files up to 700MB for downloads and 5GB for uploads, a significant increase in the file size ceiling for transfers via the Windows CLI.

Enhanced identity management - Particularly attractive for administrators in the enterprise, this release provides more flexibility and options when managing roles, domains, users and groups in the new Horizon-based public cloud console. Specifically, roles can now be assigned to groups of users, or domain administrators can be defined for managing domains and respective users. In addition, you can assign roles around the latest platform services, such as the new HP Cloud Relational Database service.

As a domain admin, you can manage each user's projects, roles, and groups. You can manage the membership of each group, and manage the user assignment within each role.

Hybrid cloud focus - In response to significant feedback received from our rapidly growing open source developer community, and the notably modest usage of the AWS EC2 API in the open HP Cloud environment, support for the AWS EC2 API and Eucalyptus API have been discontinued at this time.

Jclouds support - Jclouds support is provided for the Keystone version 2 (and earlier) API.

  • Block Storage Admin
  • CDN Admin
  • Compute Admin
  • Compute Network Admin
  • Compute Project Manager
  • DNS Admin
  • Identity Domain Admin -- Super User of the Domain; manage project role assignments including domain roles

Recommendations for version 13.5

This section of the release notes describes the HP recommendations for best performance, utility, and functionality with this software version. We have also provided information about some limitations and known issues for reference purposes. This section contains

Recommendations

The following are our best-practices recommendations for versions 13.5.

Cloud Compute

  • For best performance and reliability with multiple instances, launch instances in batches of at most 100.
  • For reliability, boot instances created from an instance with flavor small or larger from an instance of flavor small or larger. For example, don't boot an instance of flavor small from an instance of flavor xsmall.
  • To ensure proper operation, do not delete an instance in shutdown state; reboot the instance to ensure it it is in Active or Error state prior to deletion.
  • Please use a root disk size of 30GB for instances with flavors larger than xsmall.
  • For improved performance, keep the size of your bootable volumes to less than 1.4TB

Cloud Networking

  • To ensure full external node access, HP recommends that you do not delete egress rules and allow those rules to remain part of their security groups.
  • To get the most timely and accurate results for your quota checks, use the Neutron networking interface.
  • To ensure that your Linux instance is able to resolve its own hostname, add an entry to the /etc/hosts file that matches the hostname. This can be accomplished by running the command: echo " -l hostname" | sudo tee -a /etc/hosts

Command-line Interface

  • For best performance when transferring large files (greater than 700MB for downloads and 1GB for uploads), use either the classic management console or the UNIX CLI utilities.
  • For easiest password reset, use the HP Public Cloud Console interface or the classic management console or the UNIX CLI utilities.
  • Use the classic management console to display the Flavors Details information rather than the Windows CLI.
  • To create a snapshot for an instance booted from a block volume, follow these steps for best results:
    • Shut down the instance
    • Delete the instance and wait until the volume is marked as available
    • Take a snapshot of the volume using a utility such as the python cinder binding
    • When the snapshot is complete, re-create the instance from the volume
    • Re-attach the original floating IP (if necessary) Note that the port (fixed IP address) associated with the new instance might have changed.

Windows

  • For best ease-of-use, use the management console rather than the Windows command-line interface (CLI) to attach or detach a volume.
  • For best results when deleting a volume, unmount the volume (or for Windows instances take it offline) and detach the volume prior to deleting it.
  • For optimum performance and reliability when running Windows instances, HP recommends you use flavors with sizes of 4GB or greater.
  • When creating a Windows instance, you must use a flavor of small or greater. The xsmall flavor contains a 10GB root disk, which is too small to accommodate a Windows root disk.
  • For best reliability, reboot instances of sizes standard.2xlarge, standard.4xlarge, and standard.8xlarge from within the instance.

Known issues

The following are the known issues for Version 13.5 of the HP Public Cloud software.

Cloud Block Storage

  • During backups and restores you may see an Unnecessary attribute error; this is a spurious error that has no effect on successfully completing the backup and can be ignored.

Command-line Interface

  • After successfully launching an instance if you find ssh not functioning properly, just relaunch the instance.
  • Sometimes under certain circumstances in the Windows CLI, the ls command displays some fields as blank. To view the contents of these fields, display the information using the HP Public Cloud Console interface or the classic management console or the UNIX CLI utilities. The fields are:
    • The Attached To and Server Attached To fields are may display as blank after you attach a server to a volume using the [Attach-Volume](/cli/windows/reference#Attach-Volume) command
    • The Ext Gateway field may display as blank after you execute the [Update-Router](/cli/windows/reference#Update-Router) command
    • The Assigned Network Addresses field may display as blank after you execute the [New-Server](/cli/windows/reference#New-Server) command
