  • Coalesces random writes into larger sequential transfers to avoid waiting on disks.
  • Acts as a speed-matching buffer to avoid bottlenecks in the I/O path.
  • Delivers the best cost-to-benefit ratio of any storage medium.

 

 

 

  Auto-tiering

Auto-tiering allows to store, and subsequently read, your data on the storage media with the best fit based on predefined rules, or policies. This approach to tiered storage data classes automatically finds which data sets are most accessed by applications (hot data) and places it on the fastest storage. The same is true for warm and cold data – it is automatically placed on second-tier or lower-tier storage.

All of this happens dynamically in real time yet is invisible in the background. Depending on data usage, the classification may rank up or down automatically, allowing to have the best speeds for mission- and business-critical information. Application workloads are hard to predict. Auto-Tiering is a real-time intelligent mechanism that continuously positions data on the appropriate class of storage based on how frequently the data is accessed. The result is superior application performance and lower TCO across the entire storage architecture.

 

 

  Continuous data protection

 

Continuous Data Protection (CDP) is a backup and recovery technique that replicates and time stamps every incremental change to critical dataset. In the event of data corruption from logic errors, user mistakes or malware, one can roll back to the specific point in time before the undesired update occurred. Operations may then be resumed as if the problem never happened. STORANDER Mesh System One leverages built-in CDP functionality to record every update to a volume in a separate location and time stamp it. Unlike periodic snapshots, it is fully automated and happens continuously in real time. CDP complements your backup solution without being a replacement for it.

CDP records every write I/O (or change), with a corresponding timestamp, that occurs against a protected volume. With continuous data protection, a rollback volume can be created representing any point-in-time just before the undesired event occurred. The rollback volume is then mapped to the original application server or a different one.

 

 

For example, consider a virus causing damage to your data at 2:41:36 PM: just return to the status at 2:41:35 PM with a rollback volume and serve it back to the original application server. As another example, consider a user deleting a file at 3:15 PM: let the administrator roll back to a point in time before it was deleted and restore the file from that copy. Similar to snapshot requests, one can generate periodic CDP Rollback Volumes at known-good restore points by scripting a call to a PowerShell cmdlet each time an application has been quiesced and the caches have been flushed to storage.  

  • Protect against damage from ransomware, malware and other sources of data corruption.
  • Rollback to restore a volume to an arbitrary point-in-time state within a 14-day time frame.
  • Generate known-good restore points.
  • Logs and timestamps all I/Os to the selected virtual disks.
  • Operates independent of operating system or applications.
  • No need to quiesce or interrupt applications.
  • No host agents required.
  • Easy to enable protection and create rollback volumes.

 

  Inline Data Deduplication and Compression

Deduplication analyzes blocks of data and creates a unique hash for each data block. If a new block getting written to disk has the same hash value as an already existing block, it will be replaced with an identifier that simply points to the already existing data block.

Multiple redundant copies of data can be replaced with references to a single copy, which reduces the amount of capacity needed.

 

 

 

Deduplication is most beneficial when there are multiple blocks of the same data, for example, redundancy within snapshots or VDI images.

Compression, is an algorithmic process that shrinks the size of data by first finding identical data sequences appearing in a row, and then saving only the first sequence and replacing the following identical sequences with the information on the number of times they appear in a row.

Because only the first data sequence is stored as-is, less disk space is sufficient to represent the same information again. Compression typically depends on the nature of the dataset itself - whether it is in a compressible format and how much of it can be compressed.

 

  Random Write Accelerator

Workloads such as databases often generate random write operations. These types of operations are the most expensive that can occur within a storage system and always result in a negative performance impact. This impact not only affects magnetic storage devices (HDD), but flash-based (SSD) devices as well. DataCore’s Random Write Accelerator is a mechanism within STORANDER Mesh S1 Storage System that organizes all inbound writes into a sequential pattern, therefore eliminating the penalties associated with random write operations.

In the case of SSD, random write operations cause internal fragmentation to occur. This fragmentation leads to increased garbage collection which causes even more writes to occur within the SSD (write-amplification). The result is significantly decreased performance and shortened device lifespan due to wearing.

 

  Snapshots

  • Protect volumes with point-in-time images.
  • Supports stringent Recovery Point Objectives (RPOs) without compromising business productivity.
  • Comprehensive data protection for broad range of applications, hypervisors, and operating systems.
  • Integrate seamlessly with popular 3rd party backup and recovery tools.
  • Trigger from Microsoft VSS-compatible applications and VMware vCenter.
  • Synchronize snapshots across groups of virtual disks.
  • Save snapshots in lower cost storage without taking up space on premium devices.
  • Provide “live” copy of environment for analysis, development and testing.
  • Eliminate back-up windows.
  • Recover quickly at disk speeds to a known good state.

 

 

 

DataCore Storage System works with popular 3rd party backup products to simplify end-to-end data protection and ensure rapid data recovery at a granular level.

Products from companies such as Veeam, Commvault, Microsoft, and others take advantage of STORANDER Mesh System One online snapshots to centralize backups for a wide range of applications, hypervisors, operating systems and storage devices. The combined solutions offload backups from the hosts to minimize the impact on applications. Consequently, backups can be taken more frequently to meet more stringent Recovery Point Objectives (RPOs) without compromising business productivity.

Many of the steps typically necessary to coordinate snapshots for backups have been automated so they can be scheduled at regular intervals without manual intervention.

 

  Storage and Disk Pooling

Today’s modern infrastructure has daunting storage challenges. Storage needs to be fast, flexible, efficient, scalable, and easy to augment without interruptions to the business. Storage Pooling meets these requirements. Disk pools provide the foundation for all the core functionality within STORANDER Mesh S1 Storage System.

 

 

Storage Pools are the principal constructs around storage virtualization. Any block storage device such as Flash or traditional disk may reside within the disk pool, whether it is connected via Fiber Channel, iSCSI, or directly attached. Once a pool is populated with a storage device, virtual disks can be created out of the pool and served to application servers over the fabric or network.

Avoiding vendor lock-in is extremely important today and a key benefit of storage pooling. Storage pooling allows easy addition or removal of any storage device within the disk pool. Whether expanding capacity, introducing a new flash technology or decommissioning an old storage array, storage pooling delivers the flexibility to perform all of these tasks safely and without disruption.

 

  Thin Provisioning

Even though the cost per GB is dropping, there is no need to waste space when there is a simple solution to maximize utilization of it. Thin provisioning, also referred to as virtual provisioning, provides this solution by allocating physical space in smaller pieces rather than allocating and dedicating the entire volume at provisioning time.

 

 

The volume presented appears to be the full provisioned capacity to the application servers, but nothing has been allocated until write operations occur. This not only delivers 3x better storage utilization but also eases system administration because there is no penalty for presenting large volumes to the application servers on day one.

Thin provisioning is inherent in virtual disk pools. Simply create a virtual volume from a disk pool, present it to the application servers and STORANDER Mesh S1 does the rest. Disk pools span all physical devices in the pool, and are not dependent on any host, operating system, or server hypervisor.

 

  Native policy-based storage management for VMs via integration with VMware VVol

Traditionally, vSphere admins request assistance from their storage administrator to assign storage capacity (LUNs) for new datastores. This slow, cumbersome and error-prone approach with multiple convoluted steps aggravates everyone. Furthermore, storage administrators have no visibility to which storage has been assigned to which VMs.

In order to track consumption, they either manually record the VM to LUN mappings on a spreadsheet or create one datastore per VM. This makes the management of storage infrastructure for virtualized environments complex, costly and inflexible.

STORANDER Mesh System One integrates with VMware Virtual Volumes (VVols) to eliminate all manual coordination previously required, thus enabling a self-service provisioning process. vSphere administrators can draw capacity from STORANDER Mesh System One virtual storage pools with the quality of service best suited for their workloads as part of their normal VM-creation workflow.

The storage administrators simply set up the pools once, defining which policies consumers can select to specify performance, data protection level and related options. From that point on, they can observe how much and what kind of space has been allocated to specific VMs and their snapshots.

  STORANDER Mesh S1 Veeam integration

Veeam Explorer for Storage Snapshots allows many types of restores (full VM, files, application items, etc.) from a storage snapshot. There is no real preparation needed other than having a storage snapshot in place (either ad-hoc or via an existing schedule). This is a great way to have recovery points in the middle of the day in addition to established backup jobs. Veeam Explorer for Storage Snapshots is shown in the figure below from STORANDER Mesh S1.
