The document discusses the future of cloud storage, emphasizing the transition to commoditized, virtualized, and software-defined storage systems that support both public and private cloud environments. It highlights key challenges in storage performance, availability, and the complexity of managing data across various cloud architectures, including big data and hybrid cloud storage. Additionally, it introduces GlusterFS as a solution for scalable, high-performance storage that integrates file and object storage seamlessly in cloud environments.

2. Storage Transforming to Reflect Compute
Multi-tenant / Commoditized
Virtualized Automated
shared Standardized
Scale on Free Software
In the Cloud Scale Out
Demand / OpenSource
Storage must support the public and private cloud environment
• Storage is the Achilles heel of full data center virtualization
• Storage performance, availability, capacity, & interface is the Achilles heel of public
cloud
• Big Data, data migration, multi-site consistency are the Achilles heel of hybrid cloud
Storage will look like the computing environment
• Storage should be a commoditized, virtualized, centrally managed pool
• Monolithic proprietary systems now challenged by nimble and shared network storage
• Storage becomes a software problem
• The “Google model” of storage

3. Disk Systems & Storage Interconnects
FC (FCP)
Infiniband (SRP, iSer, NFSoRDMA)
Ethernet (iSCSI, FCoE, AoE, NBD/DRBD, NFS, HTTP)
DAS vs JBOD vs SAN
SATA vs SAS vs SSD
