Plug Play Storage

• Appliance based storage without the vendor lock-in

4
Legacy Appliances pros and cons

• Pros
• Fully tested
• Cost effective
• Easy to implement
• Single vendor

• Cons
• Proprietary
• Closed system
• Inflexible
• Not best of breed

5
SAN avoidance
6
The SATArray

• All the advantages without many of the
  disadvantages
• Brings together best of breed hardware and
  software from leading storage vendors
• Committed to open systems and scalability

7
SATArray Hardware

• 16 bays in 3U
• Solid State memory
• Passive backplane
• Accusys RAID controller
• 6.4TB native capacity
• Redundant power supplies and fans
• Hot swap drives
• Global hot spare (or spares)
• Bad block mapping

8
SATArray Configurations

• SCSI attached storage
• Fibre attached storage
• NAS (linux based)
• NAS (Windows Storage Server)
• iSCSI standalone
• iSCSI - IPStor
• Disk backup - NetVault

9
Direct Attach Storage

• Dual SCSI (Ultra 320) or F/C (2GBit) connections
• Data transfer rates of up to 320MB/sec read and
  190MB/sec write in RAID5 configuration

10
NAS Linux based

• Remote administration through browser interface
• Windows, Linux, Unix and Mac supported
• Active directory integration
• LDAP support
• Snapshots
• Replication
• User disk quota control

11
NAS Windows Storage Server

• Cristie is a Microsoft certified partner and a
  Storage Server OEM
• Provides complete Windows integration including
  Volume Shadow Copy

12
iSCSI

• Linux based appliance running as an iSCSI target
• Browser interface for administration
• Allows a disk array to be shared between multiple
  servers
• Any server with an iSCSI initiator and the
  allocated privileges can access the storage
• Windows, Linux, AIX and Solaris
• Very flexible low cost storage

iSCSI with IPStor

• IPStor from FalconStor provides enterprise class
  storage virtualisation and data management
• Cristie has an agreement to provide a low cost
  iSCSI appliance running the IPStor software on a
  Linux platform
• Snapshots, timemark, replication

15
Disk backup appliance with NetVault

• OEM arrangement with Bakbone for NetVault
  software
• 1GB virtual tape on disk and 10 client licenses
• Disk staging (disk to disk to tape) appliance
• SCSI connection on the SATArray to connect
  directly to a tape library
• Backups and restores administered from an admin
  console

16
Summary

• SATA technology is changing the landscape of disk
  storage
• SATA2 delayed but expected within 3 months
• Enterprise features such as predictive drive
  failure being built into firmware
• MAID for backup applications available early 2005
• Low cost, flexible and easy to install and manage
