Understanding Software Defined Storage (SDS)

Software defined storage is an evolution of storage technology in cloud era. It is a deployment of storage technology without any dependencies on storage hardware. Software defined storage (SDS) eliminates all traditional aspect of storage such as managing storage policy, security, provisioning, upgrading and scaling of storage without the headache of hardware layer. Software defined storage (SDS) is completely software based product instead of hardware based product. A software defined storage must have the following characteristics.

Characteristics of SDS

  • Management of complete stack of storage using software
  • Automation-policy driven storage provisioning with SLA
  • Ability to run private, public or hybrid cloud platform
  • Creation of uses metric and billing in control panel
  • Logical storage services and capabilities eliminating dependence on the underlying physical storage systems
  • Creation of logical storage pool
  • Creation of logical tiering of storage volumes
  • Aggregate various physical storage into one or multiple logical pool
  • Storage virtualization
  • Thin provisioning of volume from logical pool of storage
  • Scale out storage architecture such as Microsoft Scale out File Servers
  • Virtual volumes (vVols), a proposal from VMware for a more transparent mapping between large volumes and the VM disk images within them
  • Parallel NFS (pNFS), a specific implementation which evolved within the NFS
  • OpenStack APIs for storage interaction which have been applied to open-source projects as well as to vendor products.
  • Independent of underlying storage hardware

A software defined storage must not have the following limitations.

  • Glorified hardware which juggle between network and disk e.g. Dell Compellent
  • Dependent systems between hardware and software e.g. Dell Compellent
  • High latency and low IOPS for production VMs
  • Active-passive management controller
  • Repetitive hardware and software maintenance
  • Administrative and management overhead
  • Cost of retaining hardware and software e.g. life cycle management
  • Factory defined limitation e.g. can’t do situation
  • Production downtime for maintenance work e.g. Dell Compellent maintenance

The following vendors provides various software defined storage in current market.

Software Only vendor

  • Atlantis Computing
  • DataCore Software
  • SANBOLIC
  • Nexenta
  • Maxta
  • CloudByte
  • VMware
  • Microsoft

Mainstream Storage vendor

  • EMC ViPR
  • HP StoreVirtual
  • Hitachi
  • IBM SmartCloud Virtual Storage Center
  • NetApp Data ONTAP

Storage Appliance vendor

  • Tintri
  • Nimble
  • Solidfire
  • Nutanix
  • Zadara Storage

Hyper Converged Appliance

  • Cisco (Starting price from $59K for Hyperflex systems+1 year support inclusive)
  • Nutanix
  • VCE (Starting price from $60K for RXRAIL systems+support)
  • Simplivity Corporation
  • Maxta
  • Pivot3 Inc.
  • Scale Computing Inc
  • EMC Corporation
  • VMware Inc

Ultimately, SDS should and will provide businesses will worry free management of storage without limitation of hardware. There are compelling use cases of software defined storage for an enterprise to adopt software defined storage.

Dell to discontinue Compellent after merger–make sense

There are too many eggs on the busket already. Would Dell continue to sell identical products in different name or stream line all products. Dell is after streamlining all products. It is well known by Dell loyal customer that EqualLogic will disappear from Dell product line at 2018. We learnt that in Dell partner’s conference. Then question will remain what will happen to Compellent? In current market place, VNX directly compete with Dell Compellent. But VNX has more customer base than Compellent. VNX is in market for almost 20 years and still growing fast. Compellent is in new shape and in market with SC series product line. But Compellent has frustrated its customer with poor performance and poor customer support. A very poor explanation and guidelines from Dell presales team on how to align Dell storage with business requirement.

Dell can offer customer will both VNX and Compellent knowing Compellent did not work from the beginning or Dell streamline its product and kill Compellent all together. Then promote VNX as it worked past 20 years and has a proven track record. Killing Compellent will disturb few already unhappy customer who simply wanted cheap SATA disks. But killing VNX will disturb wide range of customers and annoy them once and for all. Consequence of that would be losing customers to HP and NetApp which dell desperately wants to avoid and gain control of storage market. This way Dell-EMC will retain undisputed title of EMC as a number one storage vendor. This make sense for any non IT savvy walking on the street. I am certain and believe that Dell will discontinue Compellent serries all together.  Protecting $67 billion dollar acquisition of EMC is more important than protecting $960 million acquisition of Compellent. It would obviously make sense for Michael Dell to kill Compellent and promote VNX as a sole mid range storage.

Dell-EMC: What Storage Customers Should Do

Veeam integrate with EMC and NetApp Storage Snapshots!

Taking a VMware snapshots and Hyper-v checkpoint can produce a serious workload on VM performance, and it can take considerable effort by sys admin to overcome this technical challenge and meet the required service level agreement. Most Veeam user will run their backup and replication after hours considering impact to the production environment, but this can’t be your only backup solution. What if storage itself goes down, or gets corrupted? Even with storage-based replication, you need to take your data out of the single fault domain. This is why many customers prefer to additionally make true backups stored on different storage. Never to store production and backup on to a same storage.

Veeam1

Source: Veeam

Now you can take advantage of storage snapshot. Veeam decided to work with storage vendor such as EMC and NetApp to integrate production storage, leveraging storage snapshot functionality to reduce the impact on the environment from snapshot/checkpoint removal during backup and replication.

Supported Storage

  • EMC VNX/VNXe
  • NetApp FAS
  • NetApp FlexArray (V-Series)
  • NetApp Data ONTAP Edge VSA
  • HP 3PAR StoreServ
  • HP StoreVirtual
  • HP StoreVirtual VSA
  • IBM N series

Unsupported Storage

  • Dell Compellent

NOTE: My own experience with HP StoreVirtual and HP 3PAR are awful. I had to remove HP StoreVirtual from production store and introduce other fibre channel to cope with workload. Even though Veeam tested snapshot mechanism with HP, I would recommend avoid HP StoreVirtual if you have high IO workload.

Benefits

Veeam suggest that you can get lower RPOs and lower RTOs with Backup from Storage Snapshots and Veeam Explorer for Storage Snapshots.

Veeam and EMC together allow you to:

  • Minimize impact on production VMs
  • Rapidly create backups from EMC VNX or VNXe storage snapshots up to 20 times faster than the competition
  • Easily recover individual items in two minutes or less, without staging or intermediate steps

As a result of integrating Veeam with EMC, you can backup 20 times faster and restore faster using Veeam Explorer. Hence users can achieve much lower RPOs (recovery point objectives) and lower RTOs (recovery time objectives) with minimal impact on production VMs.

How it works

Veeam Backup & Replication works with EMC and NetApp storage, along with VMware to create backups and replicas from storage snapshots in the following way.

Veeam2

Source: Veeam

The backup and replication job:

  1. Analyzes which VMs in the job have disks on supported storage.
  2. Triggers a vSphere snapshot for all VMs located on the same storage volume. (As a part of a vSphere snapshot, Veeam’s application-aware processing of each VM is performed normally.)
  3. Triggers a snapshot of said storage volume once all VM snapshots have been created.
  4. Retrieves the CBT information for VM snapshots created on step 2.
  5. Immediately triggers the removal of the vSphere snapshots on the production VMs.
  6. Mounts the storage snapshot to one of the backup proxies connected into the storage fabric.
  7. Reads new and changed virtual disk data blocks directly from the storage snapshot and transports them to the backup repository or replica VM.
  8. Triggers the removal storage snapshot once all VMs have been backed up.

VMs run off snapshots for the shortest possible time (Subject to storage array- EMC works better), while jobs obtain data from VM snapshot files preserved in the storage snapshot. As the result, VM snapshots do not get a chance to grow large and can be committed very quickly without overloading production storage with extended merge procedure, as is the case with classic techniques for backing up from VM snapshots.

Integration with EMC storage will bring great benefit to customers who wants to take advantage of their storage array. Veeam Availability Suite v9 will provide the chance to reduce IO on to your storage array and bring your SLA under control.
