•  Active data owned by high-performance Avere FXT cluster •  In-active data owned by Mass Storage System (MASS) •  Offers a global view of all MASS filesystems locally & remotely •  Avere algorithms monitor access patterns & manage data location •  Policy mgmt keeps FXT cluster in sync with MASS for backup, etc.

Customer Benefits

•  Performance acceleration: Active data moved to RAM, SSD, SAS •  Cost savings: 5:1 reduction in disks, power, space •  Simplicity: Seamless fit with existing clients, NAS servers •  Scaling: Efficient, non-disruptive growth through clustering •  Ease of management: Global Name Space & WAN capable


Performance & capacity scale independently, more efficiently

Global Namespace

•  Join exports from multiple MASSes into GNS

•  Support heterogeneous MASS vendors & models

•  Clients access all exports/MASSes from a single mountpoint, single IP

•  NFS & CIFS support, simpler than automounter & DFS, no extra server

•  Newly added exports are visible to clients without client reboot

•  GNS “logical view” is admin-defined on Avere UI, client’s view of namespace

•  Nesting of exports/junctions not supported

Migration

•  Non-disruptive migration between two MASSes (see below) •  Export is the unit of migration •  Enables…

–  Moving exports to a newly installed MASS –  Moving exports from an overloaded MASS –  Moving exports from a soon-to-be-decommissioned MASS

•  Checkpoints implemented, don’t need to restart if A or B fails •  Resources consumed, peak performance not available

Write-Through –  Ultimate reliability –  Writes commit to Avere

nodes & MASS –  Writes limited by MASS –  Read performance scales

23

Write-Around –  Some users mount MASS

directly –  Expected during initial

installation –  Writes limited by MASS –  Reads reduced by status

check –  Selectable cache timeout

period

Write-Back –  Expected configuration –  Read & Write performance

scales –  Performance scales

independently of MASS –  Write-through scheduling to

sync with backup, etc.

Evidence


•  ESG Quote: “Conceptually, an architecture like this could quite literally change everything we thought we knew about storage and I/O. If the Avere architecture can perform as intended, it might just turn decades of thinking on its head,” said Steve Duplessie, Founder of ESG.

•  Customer Quote: ''Before we added the Avere FXT Series to our storage network, we were seriously considering replacing some of our slower mass storage systems due to their inability to keep up with client demands,” said Bryan Nielsen, IT Architect at the Salk Institute. “The introduction of the FXT into our network took the load off of these devices, breathing new life into our current storage infrastructure investments. In addition, Avere’s FXT opens up new possibilities in price, performance and size considerations for future storage investments.”

Summary


•  Right Time –  Storage industry at start of new era –  Transition from HDD to SSD has begun –  Heterogeneous Global Name Space

•  Right Architecture –  Leverage all media types –  Tiering is granular, fast, and automatic –  Support wide-range of application workloads –  Simple to deploy and manage

•  Right Team –  Unique blend of clustered storage, file system and networking

expertise –  Proven track record

•  Over provision & short stroke •  Expensive due to disks, power & space •  Forced to select expensive drive types

Caching Appliance NetApp FlexCache •  Read only work loads (non-persistent) •  One protocol (NFS) limitation typical •  Limited scaling

SSD Adapter NetApp PAM, Fusion IO

•  Inability to scale separately from server •  Proprietary (NetApp) •  Integration burden placed on end-user (Fusion IO)

SSD Array EMC, Texas Memory Systems

•  High media cost •  Wasteful, copy entire volume to SSD •  Limited Tier-0 management

Switch F5/Acopia •  Disruptive, non-transparent •  Data migration between tiers is slow •  Poor performance for small-file apps
