XtremIO Kunden-Erfahrungen “We had eight racks worth of storage at

our site running 10,000 VMs. Running XtremIO we have half a rack worth. The difference is staggering.”

“XtremIO ist für uns genau die richtige Infrastruktur um die Telekom “Managed Workplace” VDI Plattform zu realisieren. Damit wollen wir wachsen!”

“It used to require eight minutes to deploy one 40 GB virtual desktop image. By comparison, with XtremIO it takes 17 seconds. It blew our mind.”

“A single copy of our database takes up 1.6TB. 20, 30, 40 copies of the database— they still take up only 1.6TB and the performance is on par with production. It’s almost like providing free databases for our developers. This completely solves our dev/test challenge.”

Fazit Wie Sie mit ScaleIO Ihre TCO senken

1. Handelsübliche Hardware

2. Keine dedizierten Speicherkomponenten (FC-Netzwerk, HBAs usw.)

3. Weniger Strom-, Kühlungs- und Platzbedarf

4. Keine „Forklift“-Upgrades für EOL-HW

5. Weniger Verwaltungsoverhead

6. Lineare Investitionen nach dem „Pay-as-you-grow“-Ansatz mit planbaren Kosten
