A Block and File Data Migration Solution

Consolidates storage and reduces risk

Data migrations are viewed as problematic by almost every size organization with administrative overhead, cost, downtime and risk among the problems most commonly cited in executing on them. For mid-sized organizations, these issues are compounded as they have the same challenges as larger organizations but fewer resources with which to perform them. This is why the RELDATA 9240i, that delivers block and file data migrations on a single unified storage platform, may just be the answer that mid-sized organizations seek.

At its core, the RELDATA 9240i is a unified storage platform that supports both block (iSCSI) and file (CIFS and NFS) storage protocols. This combined NAS and SAN functionality makes the 9240i an appealing consolidation solution for mid-sized organizations wanting to eliminate the costs associated with supporting and servicing separate block-based and file-based storage infrastructures.

The challenge is block and file data migrations are often handled in the context of either "one" or "the other".  Many times organizations have to obtain specific services and software to perform the data migration of the block based data and then another set of services and software to do the migration of the file-based data.

The RELDATA 9240i changes this approach as it includes a data migration facility that can move either block or file data as it migrates data in three distinct ways.

  • Non-disruptive data migration of iSCSI and/or fibre channel (FC) attached storage. If an organization needs to continue running the application while the data migration occurs, the 9240i can non-disruptively migrate data from an existing FC or iSCSI storage array to the 9240i. To do so, the 9240i is first configured to detect the LUNs presented by the other storage array to the application server. The 9240i then copies the data from the LUNs assigned to that application server to its own internal storage. Once the data migration is complete, the application is then briefly taken offline and reconfigured to access its data that is now on LUNs on the 9240i.
  • Non-disruptive file migration of NAS storage. To migrate data from an existing NAS file server to the 9240i unified storage solution, the 9240i takes a slightly different tactic. The 9240i first discovers all files and folders on the existing NAS file server and then does a file level migration copying all files and folders from the existing filer to the 9240i.
  • Offline data migration of iSCSI and/or fibre channel (FC) attached storage. In some instances, customers will not have a requirement to keep their storage systems and applications online which will allow them to go offline and perform the data migration.   Using this type of data migration, the application that is using an iSCSI or FC LUN is simply taken offline. The 9240i is then given access to this LUN and copies all of the data to its own internal storage. Once the migration is complete, the 9240i then presents the new LUNs on the 9240i to the application server via an iSCSI interface.

The two non-disruptive data migration techniques do not require that the application sustains an outage or be taken offline while the data is being copied. It is only when all of the data is copied that organizations should prepare for some level of application disruption. The length of the outage will depend upon what type of data migration just took place.

In the case of the block-based data migrations to the 9240i where an organization is going from FC to iSCSI, the application server(s) will need to be re-configured to discover and access its LUNs via the iSCSI interface presented by 9240i.

The level of time that an application needs to be offline will depend primarily upon how long it takes to configure the application server to access the LUNs via the 9240i iSCSI interface. Once that re-configuration is complete, the application server should be able to access the LUNs on the 9240i and resume processing.

If doing a file level migration, the length of time it takes to switch over to the 9240i and access the files and folders on the 9240i depends primarily upon the number of files that changed while the data migration was going on and the time it takes to get these files on the 9240i in sync with the NAS server. However the 9240i can verify about 1 TB of data in around 30 minutes so it is probable that that the sync will complete fairly quickly and that an organization can start accessing files on the 9240i in a short period of time.

The RELDATA 9240i takes many of the concerns that mid-sized organizations have with block and file migrations off the table. It eliminates the need to purchase third party software or specialized services to perform either of these types of migrations while facilitating the consolidation of these different storage types onto a single platform. But maybe most importantly to these organizations, the 9240i reduces the level of application disruption and risk that data migrations normally introduce to a level that is acceptable and manageable by the IT staff of any mid-sized organization.

The past few years have seen a huge increase in the amount of critical IT services that companies outsource to SaaS/IaaS/PaaS providers, be it security, storage, monitoring, or operations. Of course, along with any outsourcing to a service provider comes a Service Level Agreement (SLA) to ensure that the vendor is held financially responsible for any lapses in their service which affect the customer’s end users, and ultimately, their bottom line. SLAs can be very tricky to manage for a number ...

We called these people by various names like programmers, coders, techies, and they usually worked in a world oblivious of the everyday pri...
The “Digital Era” is forcing us to engage with new methods to build, operate and maintain applications. This transformation also implies an evolution to more and more intelligent applications to better engage with the customers, while creating significant market differentiators. In both cases, the cloud has become a key enabler to embrace this digital revolution. So, moving to the cloud is no longer the question; the new questions are HOW and WHEN. To make this equation even more complex, most ...
Some journey to cloud on a mission, others, a deadline. Change management is useful when migrating to public, private or hybrid cloud environments in either case. For most, stakeholder engagement peaks during the planning and post migration phases of a project. Legacy engagements are fairly direct: projects follow a linear progression of activities (the “waterfall” approach) – change managers and application coders work from the same functional and technical requirements. Enablement and develo...

You know you need the cloud, but you’re hesitant to simply dump everything at Amazon since you know that not all workloads are suitable for cloud. You know that you want the kind of ease of use and scalability that you get with public cloud, but your applications are architected in a way that makes the public cloud a non-starter. You’re looking at private cloud solutions based on hyperconverged infrastructure, but you’re concerned with the limits inherent in those technologies.
For DevOps teams, the concepts behind service-oriented architecture (SOA) are nothing new. A style of software design initially made popular in the 1990s, SOA was an alternative to a monolithic application; essentially a collection of coarse-grained components that communicated with each other. Communication would involve either simple data passing or two or more services coordinating some activity. SOA served as a valid approach to solving many architectural problems faced by businesses, as app...
