Windows Server 2016 Hyper-V Backup Rises to the challenges

Introduction

In Windows Sever 2016 Microsoft improved Hyper-V backup to address many of the concerns mentioned in our previous Hyper-V backup challenges Windows Server 2016 needs to address:

  • They avoid the need for agents by making the API’s remotely accessible. It’s all WMI calls directly to Hyper-V.
  • They implemented their own CBT mechanism for Windows Server 2016 Hyper-V to reduce the amount of data that needs to be copied during every backup. This can be leveraged by any backup vendor and takes away the responsibility of creating CBT from the backup vendors. This makes it easier for them to support Hyper-V releases faster. This also avoids the need for inserting drivers into the IO path of the Hyper-V hosts. Sure the testing & certification still has to happen as all vendors now can be impacted by a bug MSFT introduced.
  • They are no longer dependent on the host VSS infrastructure. This eliminates storage overhead as wells as the storage fabric IO overhead associated with performance issues when needing to use host level VSS snapshots on the entire LUN/CSV for even a single VM.
  • This helps avoid the need for hardware VSS providers delivered by storage vendors and delivers better results with storage solution that don’t offer hardware providers.
  • Storage vendors and backup vendors can still integrate this with their snapshots for speedy and easy backup and restores. But as the backup work at the VM level is separated from an (optional) host VSS snapshot the performance hit is less and the total duration significantly reduced.
  • It’s efficient in regard to the number of data that needs to be copied to the backup target and stored there. This reduces capacity needed and for some vendors the almost hard dependency on deduplication to make it even feasible in regards to cost.
  • These capabilities are available to anyone (backup vendors, storage vendors, home grown PowerShell scripts …) who wishes to leverage them and doesn’t prevent them from implementing synthetic full backups, merge backups as they age etc. It’s capable enough to allow great backup solutions to be built on top of it.

Let’s dive in together and take a closer look.

How to Deploy and Manage Storage Spaces Direct Cluster using SCVMM 2016?

Windows Server 2016 – Storage Spaces Direct Hyper-converged [image credit: Microsoft]

Introduction

With the release of Windows Server 2016, Microsoft is introducing Storage Spaces Direct (S2D), which enables building highly available Software-Defined Storage systems with local attached storage. This storage can be leveraged by VMs running on the same cluster (in hyper-converged mode) or the storage can be presented as a File Share (in disaggregated mode). The hyper-converged deployment scenario has the Hyper-V (compute) and Storage Spaces Direct (storage) components on the same cluster. Virtual machine’s files are stored on local CSVs. Once Storage Spaces Direct is configured and the CSV volumes are available, configuring and provisioning Hyper-V is the same process and uses the same tools that you would use with any other Hyper-V deployment on a failover cluster.

Seagate introduces 60TB SSD drive
Posted by Oksana Zybinskaya on August 16, 2016
5/5 (1)

Seagate shows off two new SSD products: an 8TB NVMe drive and a spacious 60TB SSD prototype in a 3.5-inch form factor.

This 60TB consists of more than a 1,000 Micron 3D NAND dice fitted into a full-size, 3.5-inch disk form factor package. Apparently, it has dual port 12Gbit/s SAS interface and 150,000 random read IOPS, with undisclosed write IOPS. The sequential read/write numbers should be 1.5 and 1.0GB/sec.

Shared virtual hard disks in Hyper-V 2016

Datacenter

A new feature called VHD Set for Hyper-V in Windows Server 2016 has been introduced by Microsoft. It allows sharing virtual hard disks between several servers in order to implement guest cluster easily without using complex technologies such as NPIV, virtual HBA, or virtual SAN.

As VHD Set, Shared VHDX enables sharing a virtual hard disk between multiple virtual machines. This feature is useful for implementing a guest cluster where shared disks are required (e.g., SQL Server AlwaysOn/FCI or File Servers).

Manage storage QoS Policies from VMM 2016
Posted by Romain Serre on June 17, 2016
5/5 (1)

The QoS policy was a feature included in Windows Server 2012 R2 that enabled to set a minimum and a maximum IOPS on a VHD(X). These policies were not centralized and you had to set the QoS policy on each VHD(X) independently.

In Windows Server 2016, Microsoft has improved this feature because the policy can now be stored in the cluster database. You can create a policy based on a minimum / maximum IOPS and/or a bandwidth. This policy can be applied to a VHD(X) (Dedicated Policy Type) or to a set of VHD(X) (Aggregated policy Type).

SanDisk is one of few companies currently offering 1TB of storage in a single-sided M.2 card – its product  X400 SSD. X400 also comes in a 2.5″ 7mm-height form factor, but the M.2 configuration is the main selling point of this line. 1TB M.2 X400 card allows getting the most out of the ultra-thin notebooks in terms of storage, without sacrificing performance or battery life.1SanDisk-X400

HYPER-CONVERGENCE TAKES HOLD
Posted by Jon Toigo on February 18, 2016
4.38/5 (8)

Hyper-converged infrastructure, when we started to hear about it last year, was simply an “appliantization” of the architecture and technology of software-defined storage (SDS) technology running in concert with server virtualization technology. Appliantization means that the gear peddler was doing the heavy lift of pre-integrating server and storage hardware with hypervisor and SDS hardware so that the resulting kit would be pretty much plug-and-play.
