Improvements are

  • Zerto Cloud Manager (ZCM) Enhancements
  • Improved Zerto Virtual Replication Appliance (VRA) Management
  • Flexible Journal
  • Zerto Self-Service Portal Login
  • Expanded REST APIs
  • New Alerts and Events Tab

A detailed overview of what is new in version 3.1 is here.

zerto-cloud-managerZerto Cloud Manager – Simplified BC/DR Management

In ZVR 3.0, Zerto introduced the Zerto Cloud Manager (ZCM), which provided one view of all customer (or department) resources and service levels across physical locations. ZVR 3.1 extends these capabilities providing CSPs and enterprises one pane of glass for management, orchestration, reporting and monitoring of BC/DR operations across multiple sites. With the new ZCM, IT administrators can protect and mobilize production workloads between multiple locations within a single web-based user interface, all with just a few clicks.

Flexible Journal

The ZVR journal enables recovery to multiple points in time, ensuring successful recovery from disasters and logical corruptions. With 3.1, the size of the journal automatically increases and decreases based on the amount of changed data, completely eliminating the management overhead of maintaining journal size and ensuring protection even when applications generate large bursts of data.

Additional features of ZVR 3.1 include:

  • Increased manageability of alerts and events with a new centralized tab for better cause/effect analysis
  • Expanded REST API capabilities for orchestration, events and alerts
  • Improved environment maintenance using new VRA tabs and workflows

Gartner Catalyst session: Modernizing Business Continuity and DR Using Virtualization and the Cloud

One of the presentations at Gartner Catalyst Conference was titled Modernizing Business Continuity and DR Using Virtualization and the Cloud.

It can be watched online for free here. If you do not have an account you can create one for free and watch three sessions for free.

This blogpost has a summary of what was presented here.

The outline of the  presentation by Werner Zurcher is :

Server virtualization and public and private cloud services have dramatically changed the alternatives organizations have to ensure greater application availability and disaster recovery. This session provides detailed guidance on how to modernize business continuity and highlights lessons learned from bleeding edge organizations that are already using private and public clouds for DR. The key questions answered in this session include:
• How are technologies like server and storage virtualization and software-defined networks architected to improve business continuity?
• Who is enabling, and who is embracing cloud DR and for what use cases?
• What are the most common architectural pitfalls that should be avoided?

As IT is becoming more and more important organizations are looking for ways to improve their business continuity and disaster recovery capabilities. Superstorm Sandy and the Fukushima nuclear disaster in Japan increased the number of questions by Gartner customers on how to improve DR.

To start improving BC and DR, some advise from Gartner

  • IT must know the business requirement for BC and DR
  • IT should use virtualization to improve mobility, availability and DR.
  • use automation to simplify disaster recovery.
  • use the cloud to support BC management and assure IT service recovery

 

Gartner did interviews with 16 of its clients to understand how they perform BC and DR. All Gartner customers who are innovative on DR have a high degree of virtualized servers. Their servers were between 75 and 99% virtualized. That is much higher then the average. Gartner estimates that by the end of 2013 67% of all servers will be running virtualized.

Most companies have 3 to 4 tiers of application protection levels ranging from  Mission critical, critical, important and non important for example. Each tier describes uptime requirements, availability, RTO and RPO. Many companies also have a Tier 0 level for critical infrastructure components. In this level of protection are services like Active Directory, DNS and DHCP. These services need to be available at all times. Organizations do not want to rely on  restore of Microsoft AD first and only after succesfull restore start with restoring the business applications.

The slide below shows the average spending on disaster recovery by industry. Clearly banks, telecom and airlines spent the most money of their IT budget on DR.

The slide gives an indication of RTO and RPO per industry.

Benefits of server virtualization to DR

Virtualization makes DR much easier and less costly. Virtualization provides hardware abstration. VMs can run on any supported hardware platform. In the secondary datacenter used for DR less hardware is needed when servers are virtualized. Virtualization also enables using the cloud as a DR site.

DR Automation tooling

A quote of one of the Gartner customers who participated in the study was: “We’re moving away from RecoverPoint to get away from replicating everything. I want only certain things to get replicated. Also, with LUN-based replication, if everthing on the same LUN isn’t related, it gets more difficult to move or test (failover and failback).

Death to array-based replication

Dr-slide2

This quote comes from a Gartner client using Zerto Virtual Replication. They are moving to the cloud for DR this fall. In the Gartner study 10 of the 16 customers were using software replication. 7 of those 10 are using a combination of software and hardware replication (replication performed at storage level) .

<note from author: In April 2012 I did a review of Site Recovery Manager, Zerto Virtual Replication and Virtualsharp Reliable DR. Since then new versions have been released. Read the review here . 

I also blogged about using Zerto for DR to the cloud in this blogposting titled Is your data ready for the next natural disaster or other hazards to IT?

Garter recommends to separate  data of virtual machines in 3 different virtual disks.

  • Disk 1 for operating system, application software files.
  • Disk 2 for paging/swap file and temporary files
  • Disk 3 for data

Disk 1 and disk 2 only require to be replicated once per day. Replication of the page disk could be needed to reserve the storage in the DR site. Actually as the virtual machine will restart in the secondary site is case of a disaster, the replicated paging/swap files will be overwritten at startup.

Automation makes DR much easier. 6 participants of the Garner study were using VMware Site Recovery Manager. One customer was using Hyper-V Replica with system Center Orchestrator, one company was using Zerto Virtual Replication,  <note: Veeam Backup & Replication does not offer an automated recovery feature on par with the ones mentioned by Gartner)

One of the best features of DR tools is automated test failover to a DR sandbox. This allows failover to be tested without disrupting the production environment. One of the customers is quoted: Virtualization and SRM allow us to eat chips and watch TV during the DR-test.

DR to the cloud

18% of the respondents in a recent Storage Magazine survey are using Disaster Recovery to the cloud (aka Recovery as a Service RaaS). Those were all small companies. Large companies all operate two or more datacenters which are used for DR. Gartner asked 1000 of its clients if they were using cloud for DR purposes. Only one !  was using cloud for DR, another was moving to it. Gartner got the same response on another query to 1000 respondents executed at a later date.

<note from author: I guess most of Garners clients are large organizations. The actuall usage of DRaaS in total will be higher>

So large organizations are not doing DR to the cloud yet.

An issue with DR as a Service is the bandwidth to and from the cloud. Companies are starting to use carrier Ethernet with 1Gbps links to the cloud. When looking for DraaS vendors distance between your location and that of the DraaS provider is an important thing to consider. Even when using 1 Gbps connection if the distance is too far the throughput is low/latency high. Of course the providers location should not be too close either. Gartner recommends something like between 20 and 100 miles away.

Gartner spoke to a Recovery as a Service provider. This provider has a couple of cloud based recovery services. Veeam Backup and Replication was used most by their customers. More information on using Veeam for DR here. 

Very often European organizations are using three datacenters. Two are close to eachother (arond 30 km max). Those two datacenters can be so close to eachother because in Europe there are no earthquakes , hurricanes or other natural disasters hitting a whole region. DR is done using the primary and secondary DC. When datacenters are close together it is easier for staff to get there for maintenance etc.  Some organizations like banks use a third datacenter to store data just to be sure. Or use the cloud as a third datacenter to run webservers. If both datacenters are unavailable at least some critical public facing websites remain available.

Use the Business Continuity Management tools from the cloud (SaaS).
BCM tools offer features like emergency messaging and notification services. Also they offer DR plans, business impact analysis, DR strategy, IT DR planning etc.   This can be very handy to have quick access to when a disaster have happend… <note from author: I am sure you stored Recovery plans in several safe places outside where your production data lives)>

The documentation having instructions how to recover, who to inform, contact details etc can even be accessed from a mobile Phone when using SaaS tools.

Investigate cloud DR for appropiate IT services. Cloud DR is not an all of nothing proposition. You can protect a subset of your applications using cloud DR. Get comfortable with it and extend the usage of Cloud DR when you are comfortable with it.

Test your DR plan regularly, This is what all companies do who participated in the Gartner study. However most of them did not test a failback.

Zerto announces Virtual Replication 3.0

For disaster recovery  (DR) of virtual machines running on vSphere just a few rocksolid solutions are available, in particular for enterprise environments. In April 2012 I published an overview of the three major vendors of DR solutions for vSphere. VMware Site Recovery Manager is  well known. Zerto Virtual Replication is another great solution. It is increasingly being used by enterprise sized organizations and service providers.

Today the company announced their 3.0 version.

New enterprise features include:

  • Remote Office / Branch Office (ROBO) support: Standardize protection across the organization with support for branch offices, delivering the same tight SLAs of the main office.
  • 100 percent assurance for DR testing: New ‘test-before-you-commit’ capability delivers comprehensive recovery.
  • Parallel recovery feature accelerates large application availability.

New Cloud Service Provider features include:

  • Zerto Self-Service Portal (ZSSP): Offer mission-critical protection quickly and easily with a SSP that integrates into the existing infrastructure with little to no effort.
  • Zerto Cloud Manager (ZCM): A centralized management point for CSPs to get a complete view of disaster recovery customers across multiple sites. This feature is also useful for enterprises building private clouds.
  • vCloud 5.1 seamless integration: Native support for vApps, Storage Profiles, Org Networks, Provider vDC and more.
  • VMware vCloud Automation Center (vCAC) integration: The only disaster recovery solution for vCAC environments.

The addition of features since the 1.0 release are shown in this table.

See the Zero Pressrelease  for more information.

Is your data ready for the next natural disaster or other hazards to IT?

We all know the hazards which can bring down IT-infrastructures. Hardware or software faults, human error, fire, hurricanes,  broken WAN connections, Murphy’s Law, etc.  Many believe the chance of a datacenter failure is pretty low. And many believe the costs to protect do not outweigh the risks.

With the release of Zerto Virtual Replication for VMware vSphere infrastructures costs are must lower than traditional approaches of disaster recovery which are often based at expensive storage based replication  not aware of virtual machines. Zerto changed the market for DR.

Zerto Virtual Replication offers  hypervisor-based replication for Business Continuity and Disaster Recovery for smb, enterprise and service providers. It achieves RPO in seconds, and RTO in minutes. I wrote a blogposting on an earlier version of the product back in February 2012.

In this article you will learn how Affigent LLC, a Herndon, Va.-based technology consulting firm for government customers protects it IT-infrastructure for disasters using Zerto Virtual Replication.
