the constraints of today s infrastructure
The Constraints of Today’s Infrastructure
  • Complex
    • Mixed vendors, platforms, file systems
  • Inflexible
    • Access is tightly coupled to file location
    • Disruptive to move data
  • Inefficient
    • Resources are under and over utilized
  • Growing rapidly
    • 70% annually (80% are files)

The cost of managing storage is five to ten times the acquisition cost

virtualization breaks the constraints
Virtualization Breaks the Constraints
  • Simplified access
    • Consolidated, persistent access points
  • Flexibility
    • Data location not bound to physical resources
  • Optimized utilization
    • Balances load across shared resources
  • Leverages technology
    • Freedom to choose most appropriate file storage

“File virtualization is the hottest new storage technology in plan today…” (TheInfoPro)

how will acopia work
How will Acopia work?
  • ARX acts as a proxy for all file servers / NAS devices
    • The ARX resides logically in-line
    • Uses virtual IP addresses to proxy backend devices
  • Proxies NFS and CIFS traffic
  • Provides virtual to physical mapping of the file systems
    • Managed Volumes are configured & imported
    • Presentation volumes are configured
where does acopia fit
Where Does Acopia Fit?

Users and Applications

  • Plugs into existing IP / Ethernet switches
  • Virtualizes heterogeneous file storage devices that present file systems via NFS and/or CIFS
    • NAS, File Servers, Gateways
  • Does not connect directly to SAN
    • Can manage SAN data presented through a gateway or server
  • No changes to existing infrastructure
    • ARX appears as a normal NAS device to clients
    • ARX appears as a normal CIFS or NFS client to storage
  • SAN virtualization manages blocks, Acopia manages files
    • Data management vs. storage management

how to deploy acopia in the network
ARX HA subsystem uses a 3 voting systems to avoid “split brain” scenarios

“Split Brain” is a situation where a loss in communication causes both devices in an HA pair to service traffic requests which can result in data corruption

Heartbeats are exchanged between

The primary switch

The standby switch

The Quorum Disk

The Quorum Disk is a share on a server/filer

data migration with acopia
Data Migration with Acopia
  • Solution:
    • Transparent migration at any time
    • Paths and embedded links are preserved
    • File-level granularity, without links or stubs
    • NFS and CIFS support across multiple vendors
    • Scheduled policies to automate data migration
    • CIFS Local Group translation
    • CIFS share replication
    • Optional data retention on source
    • IBM uses ARX for its data migration services
  • Benefits:
    • Reduce outages and business disruption
    • Lower operational overhead
      • No client reconfiguration
      • Decommissioning without disruption
      • Automation
data migration one for one
Data Migration (One for One)
  • Transparent migrations occur at the file system level via standard CIFS / NFS protocols
  • A file system is migrated in its entirety to a single target file system
  • All names, paths, and embedded links are preserved
  • Multiple file systems can be migrated in parallel
  • Inline policy steers all new file creations to target filer
    • No need to go back and re-scan like Robocopy or Rsync
    • No need to quiesce clients to pick up final changes
  • File systems are probed by the ARX to ensure compatibility before merging
  • The ARX uses no linking or stub technology so it is backed out easily

data migration one for one21
Data Migration (One for One)
  • File and directory structure is identical on source and target file systems
  • All CIFS and NFS file system security is preserved
    • If CIFS local groups are in use SIDs will be translated by the ARX
  • File Modification and Access times are not altered during the migration
    • The ARX will preserve the create time (depending on the filer)
  • The ARX can perform a true multiprotocol migration where both CIFS and NFS attributes/permissions are transferred
    • Robocopy does CIFS only, Rsync NFS only
  • The ARX can optionally replicate CIFS shares and associated share permissions to the target filer

data migration fan in
Data Migration: Fan In
  • Fan in migration allows admin to take advantage of larger/more flexible file system capabilities on new NAS platforms
  • Separate file systems can be merged an migrated into a single file system
  • The ARX can perform a detailed file system collision analysis before merging file systems
    • A collision report is generated for each file system
    • Admin can choose to manually remove collisions or let the ARX rename offending files and directories
  • Like directories will be merged
    • Clients see aggregated directroy
  • In cases where the directory name is the same but has different permissions the ARX can synchronize the directory attributes

data migration fan out
Data Migration: Fan Out

Client View

  • Fan out migration allows admin to change sub optimal data layout due to reactive data management policies
  • Structure can be re-introduced into the environment via fileset based policies that allow for migrations using:
      • Anything in the file name or extension
      • File path
      • File age (last modify or last access)
      • File size
      • Include of exclude (all files except for)
      • Any combination (union or intersection)
      • For the more advanced user regular expression matching is available
  • Rules operate “in-line”
    • Any new files created are automatically created on the target storage, no need to re-scan the source again

data migration name preservation
Data Migration: Name Preservation
  • Acopia utilizes a name based takeover method for migrations in most cases
    • No 3rd party namespace technology is required, however DFS can be layered over ARX
  • All client presentations (names, shares, exports, mount security) are preserved
  • The source filer’s CIFS name is renamed and then the original name is transferred to the ARX allowing for transparent insertion of the ARX solution
    • This will help avoid issues with embedded links in MS-Office documents
  • The ARX will join Active Directory with the original source filer CIFS name
  • If WINS was enabled on the source filer it is disabled, and the ARX will assume the advertisement of any WINS aliases
  • For NFS the source filers DNS entry is updated to point to the ARX
    • Or auto-mounter/DFS maps can be updated
  • The ARX can assume the filers IP address if needed

Load Balancing

Application

  • A common problem for our customers is applications that require lots of space
    • Administrators are reluctant to provision a large file system, because if it ever needs to be recovered it will take too long
    • They tend to provision smaller file systems and force the application deal with adding new storage locations
    • This typically requires application down time and complexity being added to the application
  • The ARX can decouple the application from the physical storage so that the application only needs to know a single storage location
    • The application will no longer need to deal with multiple storage locations
  • The storage administrator can now keep file systems small and dynamically add new storage without disruption
    • No more down time when capacity thresholds are reached
