Virtualization Backup

Virtualization Backup focuses upon data backup, recovery and protection in virtualized and cloud environments. Data protection is no longer the realm of just backup but is about recovery while maintaining business continuity. The recovery of data is important. (Read More)

Backup, Data Protection, Business Continuity, Disaster Recovery, and Continuous Data Protection are all covered as they pertain to virtualized and cloud environments; the passing of data between environment; and the increasing scale of data to be protected in shorter periods of time. Virtualization Backup looks at how applications and data interact to allow for speedier recovers with less data loss while making use of onsite and cloud based technologies.

Cisco Acquires Cloupia – Becoming a Management Software Vendor?

VirtualizationManagementIconOn November 15th, Cisco announced that it was acquiring Cloupia a cloud management startup that had built a unique combination of physical provisioning for converged infrastructures like the Cisco UCS and its downstream partner bundles like vBlocks and NetApp Flexpods with the ability to automate the provisioning of IaaS clouds on these converged infrastructures. Cisco had previously acquired Tidal Software, a vendor specializing in monitoring SAP in production, and newScale, a vendor who arguably lead the market for enterprise grade service catalogs.

Datasores: Where are yours?

VirtualizationBackupA typo report on twitter has lead me to a set of thoughts with respect to data. Where are your Datasores? What is a datasore? Unlike a Data Store which holds data, a datasore is a place where data becomes either painful to manage or protect. Or where the data exceeds your capability to handle it. A data sore should never happen, but with the explosion of data being moved, protected, managed, and mined we have exceeded certain limits of our existing set of tools. How do we find data sores and alleviate them? Does alleviating them require us to re-architect our entire data usage and storage mechanisms? Continue reading Datasores: Where are yours?

Data Protection for Free: What are the Limits

VirtualizationBackupIt is possible to get data protection for your virtual and cloud environments for free today, but there are are often limits. Trialware as it is called provides just enough of a taste for the data protection tool to convince you to buy the versions with more capabilities. However, for the SMB, the free versions may be good enough. The concept of ‘good enough’ is one that travels through the virtualization and cloud environment architectures with respect to security, data protection, and hypervisor feature sets as often as higher licensing levels are mentioned, why, because cost matters. But from a data protection perspective what do you get for free? Here is a short comparison of the free products and features. Continue reading Data Protection for Free: What are the Limits

Move to the Cloud: Wait Out the Storm

VirtualizationBackupThe east coast is experiencing the tail end of a very large storm named ‘Sandy’. We all had plenty of time to prepare for the storm, but did we? Individually, we probably did, but what about our data? Those 24/7 critical processes to allow our customers to view and respond to the data our organizations provide? We were lucky—we had no issues during the storm, but now we await issues during storm clean up. So how do you prepare for such disasters? Do you move to the cloud? Continue reading Move to the Cloud: Wait Out the Storm

New Breed of Replication Receiver Clouds

VirtualizationBackupThere is an ever-increasing number of data protection providers creating replication receiver clouds as they team up with cloud service providers. This could herald the end of on-premise tape use for some enterprises, leaving tape to be used primarily by cloud providers. There are major benefits for Quantum, Zerto, Veeam, and others to form replication receiver clouds, but these clouds are not just for storage anymore. They could be purely for storage, but this is not a big win for the cloud service providers. So why would cloud service providers be interested in being a storage endpoint for data protection? Why are they concerned with backup and offering it as a service? Continue reading New Breed of Replication Receiver Clouds

VMworld 2012: Important New Features in vSphere 5.1

VMware100x30While not a major version release (we will have to wait for 6.0 next year for that), the new 5.1 version of the VMware products contains some significant new functionality, in addition to the packing of all of the components into the vCloud Suite.

New Features in vSphere 5.1

  • User Access – There is no longer a dependency on a shared root account. Local users assigned administrative privileges automatically get full shell access
  • Auditing – All host activity from both the shell and the Direct Console User Interface is now logged under the account of the logged in user
  •  Monitoring – Support is added for SNMPv3. The SNMP agent has been unbundled from the VMkernel and can now be independently updated.
  • vMotion – a vMotion and an Storage vMotion can be combined into one operation. This allows a VM to be moved between two hosts or clusters that do not have any shared storage.
  • New Windows Support – Support for both the Desktop and Server Editions of Windows 8/2012
  • Hardware Accelerated 3D Graphics – Teaming up with NVIDIA, vSphere can now map a vGPU to each VM on a system. Not only does this feature accelerate 3D graphics but provides a GPU for high performance computing needs
  • Improvements in Virtual hardware virtualization support – This brings Intel-VT/AMD RVI features further into the virtual machine which will improve virtualization within virtualization. In addition, more low level CPU counters are exposed which can be further used for high performance computing and real time style applications.
  • Agentless Antivirus and Antimalware – vShield Endpoint is now included in vSphere 5.1 and offloads anti-virus and antimalware processing inside virtual machines to a secure dedicated virtual appliance delivered by VMware partners. This change lowers the cost of entry for Agentless Angivirus and Malware.
  • New 64-vCPU Support – Virtual machines running on a vSphere 5.1 host can be configured with up to 64 virtual CPU’s and 1TB of RAM.
  • Auto-Deploy – Auto-Deploy is extended with two new modes, “stateless caching” and “stateful installs”. In addition the number of concurrent reboots per Auto-Deploy host has been increased to 80
  • SR-IOV Support – Single Root I/O Virtualization allows certain Intel NIC’s to transfer data directly into the memory space of a virtual machine without any involvement from the hypervisor. See this Intel Video
  • Space Reclaiming Thin Provisioned Disks – These types of disks add the ability to reclaim deleted blocks from existing thin provisioned disks while the VM is running. To reclaim space is a two-part function of first wiping the disk marking unused blocks as free, and then to shrink the disk. These two features have been a part of VMware Tools for a number of years but now do things differently for thin provisioned disks. The underlying hardware is not initially part a part of the reclamation process. Instead the vSCSI layer within ESX reorganizes unused blocks to keep the used part of the thin provisioned disk contiguous. Once the unused parts are at the end of the thin provisioned disk then the hardware is involved.
  • Tunable Block Size – Normally thin provisioned disks use a 4KB block size that is unchanging, however, this block size can be tuned indirectly as it is now based on the requirements of the underlying storage array. There is no method to tune this by hand.
  • All Paths Down Improvements – When there was an all paths down (APD) situation, the vSphere management service would hang waiting on disk IO, which would cause the vSphere host to inadvertently disconnect from vCenter and in effect become unmanageable. APD handling has been improved such that transient APD events will not cause the vSphere management service to hang waiting on disk IO, use of vSphere HA to move workloads around to other hosts if APD detects a permanent device lost (PDL) situation, and implement a way to detect PDL for iSCSI arrays that present only one LUN.
  • Storage Hardware/Software improvements – These improvements include the ability to boot from software FCoE, additions of Jumbo frame support for all iSCSI adapters (software or hardware), and support for 16Gb FC
  • VAAI Improvements – VAAI has added support to allow vCloud Director fast-provisioned vApps to make use of VAAI enabled NAS array-based snapshots.
  • vSphere S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) Implementation – vSphere has implemented SMART reporting via the esxcli commands so that SSD and other disks can report back on their status. In addition, esxcli has been upgraded to include ways to reset specific FC adapters directly as well as methods to retrieve event caching information such as link-up and link-down.
  • Storage IO Contral Statistics and Settings Improvements – Finding the proper value for SIOC has been problematic, now it is possible to set a percentage instead of a millisecond value to determine when SIOC should fire. In addition, SIOC will report stats immediately instead of waiting. This allows Storage DRS has statistics available immediately, which improve its decision process. In addition, the observed latency of a VM (a new metric) is available within the vSphere Client performance charts. The observed latency is latency within the host and not just latency after storage packets leave the host
  • Storage DRS Improvements – Storage DRS has been improved for workloads using vCloud Directory. Linked clones can now be migrated between datastores if there exists either the base disk or a shadow copy of the base disk. Storage DRS is also used now for initial placement of workloads when using vCloud Director.
  • Improvements in Datastore Correlation for Non-VASA enabled arrays – For storage devices that do not support VASA it is difficult to correlate datastores against disk spindles on an array. There are now improvements in the datastore correlation such that vSphere can now detect if spindles are shared by datastores on the array regardless of VASA support.

Summary

By exposing virtual hardware (Intel-VT/AMD RVI) virtualization as well as more CPU counters and components VMware has exposed more capability than ever before. Tie this with virtual graphics processing units and we now have the ability to implement virtualized high performance and real-time computing environments. Add to this the storage improvements and large scale big data applications as well as high performance computing environments can be virtualized. Both require low latency networking and storage.

Virtualization has long since been the bane of high performance applications whether that is 3D graphics, high performance computing, big data, or real-time applications. vSphere 5.1 provides a possible solution to use cases while improving integration with the VMware vCloud Suite.
