NetApp - The Virtual Storage Guy

A “Multivendor Post” to help our mutual iSCSI customers using VMware

Today’s post is one you don’t often find in the blogosphere, see today’s post is a collaborative effort initiated by Chad Sakac (EMC), which includes contributions from Andy Banta (VMware), Vaughn Stewart (NetApp), Eric Schott (Dell/EqualLogic), and Adam Carter (HP/Lefthand), David Black (EMC) and various other folks at each of the companies. Together, our companies make up the large majority of the iSCSI market, all make great iSCSI targets, and we (as individuals and companies) all want our customers to have iSCSI success.

Deduplication Guarantee from NetApp – Fact or Fiction?

I stumbled across these blog posts this morning.

NetApp’s ‘Shining’ Moment – its Capacity Guarantee Program follow up

 These blogs attempt to discuss the details of the NetApp 50% Virtualization Guarantee Program. This program is one of the many means by which NetApp is helping customers reduce their storage spenditures and carbon footprint by reducing the amount of storage required to run their virtual infrastructures.

The blog’s author, Jim Haberkorn, made the point that the guarantee program includes a requirement that compares NetApp RAID-DP against traditional storage systems running RAID 10.

I believe the point Jim is trying to make in his posts is, 'RAID-DP requires almost half the physical disks as RAID 10 so one should conclude that the NetApp data deduplication technology works poorly and thus the guarantee program is worthless.'
