“Cloudy storage”


Agenda

• Corporate Introduction

• NexentaStor as “Cloudy storage”

• Customer case studies

2


Opportunity

3 Nexenta Systems Inc. CONFIDENTIAL

Storage is now 42% of total IT spending and growing

Legacy storage provider solutions are inadequate

• Aged software on commodity hardware

• Lock-in business models that mark up hardware

10x

• Poor alignment with IT trends including cloud and

virtualization and the exponential growth of

unstructured data

Enterprise class storage for everyone


Enterprise Edition

+ search + synch replication

+ ease of use + remote management

Additional modules + VM management + WORM +

Windows „Deloreon‟ + HA + pNFS

• Hardware independent

• NAS/SAN/iSCSI/FC

• CDP via ZFS snapshots

• CDP via block sync

• Advanced graphics

• Event based API

Illumos kernel

multi-core + clustering

Debian / Ubuntu

#1 community + packaging

NexentaOS:

• Loves multiple cores

• Boot level ZFS

• >1 million downloads

ZFS: File system

• universal:

SAN/NAS/iSCSI/FC

• performance: variable

block size + prefetch

• Software RAID that

identifies and corrects

data corruption

ZFS checksums

Unified storage: block and file

Leading OpenStorage solution

Offers unmatched enterprise features

at 70-80% savings:

• End to end data integrity

• Unlimited file size & snaps

• Synchronous and ZFS replication

Superior storage for virtualized and cloud

environments



Key Attributes of “Cloudy Storage”

• Scalable

• Easy-to-manage

• Elastic

• Optimized for virtualized environments

• Commoditization & data integrity

6


SCALABLE ARCHITECTURE

7


Storage software designed to scale

• Multi-core support

• SSD support

• “No limits”

• Search capability

8

“just add hardware – and it

accelerates”


ZFS - pushes boundaries on limits

Description Limit

Number of data volumes on a system 264

Maximum size of a data volume 278 bytes

Number of file systems in a data volume 264

Maximum size of a file system 264 bytes

Number of devices in a data volume 264

Number of files in a directory 256

Maximum file size 264 bytes

Number of attributes of a file 248

Maximum size of any attribute 264 bytes

Number of snapshots of a file system 264

9


“Block level” Scalability

10

NFS, CIFS, etc. Each system

exports volumes

I/O “striped” across

backend systems

FC, iSCSI,

AoE, etc.


“File level” Scability

• Referrals

– Head node redirects to data servers

– NFS referrals (Q4 2010)

– DFS referrals (Q1 2011)

• pNFS

– Parallel requests across data servers

– 2011

11


NFS Referrals – scale out NAS

12


EASY TO MANAGE

13


Comprehensive management tools • Web GUI

• Command-line shell

– Auto-complete and help facility

• APIs

– Rest, Perl, PHP, C

• Scheduled storage services

– Replication, snapshots, scrubs

14

Auto deploy, auto configure

“We deploy and configure NexentaStor using Chef & pxe boot”

Nexenta Systems Inc. CONFIDENTIAL 15

Analytics with real-time data


• Asynchronous:

– Auto-Sync

• Copies ZFS volumes including metadata headers

• Can specify individual folders

– Auto-Tier

• Copies folders to and from appliances

• Synchronous

– Auto-CDP

• Optional module, block-based replication

Zero impact snapshot replication with de-duplication & WAN awareness

“World’s fastest replication”

Built in Data protection


ELASTIC

17


On-demand resource management

• Thin provisioning

• Reservations and quotas

• Volume grow

• Global name space

• Compression

• Deduplication

– In-line and post-process options

18

Add hardware. Increase pool sizes. Improve utilization. • automatically


NATIVE SUPPORT FOR VIRTUALIZATION

19


Unified storage - Virtual machines

• Only solution that unifies management of storage for Vmware, Citrix Xen and Hyper-V

• Native use of SSDS

• De-duplication

20

$68,000 spent on NexentaStor & hardware is 2x as fast as $1,000,000 of legacy storage for VDI

COMMODITIZATION

23


OpenStorage commoditization

• Customers own perpetual licenses

– Hardware refresh can proceed without any additional payment to Nexenta

– Refresh of legacy storage is often more expensive than the initial purchase

• NexentaStor with HA turns industry standard hardware into enterprise class storage

– Superior data integrity than legacy hardware

24

Every transaction atomic and checksummed. The only solution to find and correct silent data corruption.
