Power Behind the Storage

Advanced Audio Delivers Symphony Sound

Using iSCSI

Advanced Audio rentals is a leading audio equipment

rental firm in Burbank, California with clients such as

Sony Pictures, 20th Century Fox Studios, Paramount and

Warner Brothers. These companies needed a partner to

provide them with equipment to achieve the high quality

sound that is imperative for orchestral recording, post

production and film dubbing.

But what do you do when your current workflow process

does not keep pace with high definition audio technology

like Digidesign’s ProTools|HD? Realizing that quality

sound is imperative in the movie business and for or-

chestral recording, Paul Levy, owner of Advanced Audio

Rentals was determined to find a networked alternative

solution that could support all track counts and sampling

rates up to 192kHz.

With the introduction of Digidesign’s ProTools|HD, audio

engineers could now configure virtual track layouts and

use many more effects to speed workflow. Audio could

now be digitized at sampling rates up to 192kHz. Cur-

rently, the only standalone storage solution that can sup-

port 192kHz recording is FireWire 800-based. This

storage format poses multiple challenges including

mounting difficulties, lack of RAID redundancy, and track

allocation problems because one needs to use multiple

physical devices daisy-chained together in order to over-

come the IDE rotational speed limitation of 7200 RPM.

“One of the challenges I had to

resolve was that the only ports

left for connection in a Macin-

tosh® were the FireWire 800

port or the Ethernet port. Fire-

Wire based storage was not

stable enough and did not pro-

vide the robustness needed for

orchestral recording or sound

dubbing. I was intrigued by the

power of iSCSI and the ability

for facilities to use their exist-

ing backbone and wiring of 1-Gb or 10-Gb Ethernet. So I

began to research solutions,” states Paul Levy.

And so the search began for a configuration that could

be adapted to the changing needs of his clients. After

reviewing the

needs of

High Defini-

tion Audio,

Paul needed

to find a

product that

could con-

nect to the

Macintosh

Ethernet port

and also pro-

vide Fibre

Channel con-

nectivity. He

decided on

the ATTO

iPBridge™ 2700, an iSCSI-to-Fibre Channel bridge that

would provide the connectivity needed to a Fibre Channel

switch or Fibre Channel RAID storage.

Advanced Audio put together a configuration that could

be adapted to the changing needs of their clients. Fea-

turing the ATTO iPBridge 2700

and ATTO’s Xtend SAN iSCSI

initiator, clients could connect

their Macintosh via the

Ethernet port directly into 3

Terabytes of online Fibre Chan-

nel RAID storage, or use 2

Gigabytes of Fibre Channel via

the ATTO Celerity FC-42ES

Host Adapter.

“One of the challenges I had to resolve

was that the only ports left for con-

nection in a Macintosh were the Fire-

Wire 800 port or the Ethernet port.

FireWire based storage was not sta-

ble enough and did not provide the ro-

bustness needed for orchestral re-

cording or sound dubbing,” states Paul

Levy, owner of Advanced Audio Rent-

als, Burbank, California.
