A few weeks ago, I had the opportunity to get to know SolidFire and its Storage System product, an all-flash array designed for on-premises use but with some attractive cloud functionality. At first glance, the array looks like many of those in the all-flash space. It’s built out of discrete nodes; uses 10 Gbps networking to present iSCSI; does inline deduplication, compression, and best-effort real-time background replication; has copy-on-write, space-efficient snapshots; and scales linearly.
2011 saw an increase in virtualized and cloud data protection solution partnerships and advancements. One of the biggest advancements is the growing support for Microsoft Hyper-V from long-time VMware specific backup solutions. Included in the new partnerships are team ups between performance management and data protection solutions, as well as an increase in the methods for replication and other forms of data protection. 2011 was a very big year in the Data Protection arena of cloud and virtualization. This is the 2011 Year in Review for data protection. Continue reading 2011 Year in Review – Data Protection

Serial Attached SCSI (SAS) is better known as an interface for connecting hard disk drives (HDD) to servers and storage systems; however it is also widely used for attaching storage systems to physical as well as virtual servers. An important storage requirement for virtual machine (VM) environments with more than one physical machine (PM) server is shared storage. SAS has become a viable interconnect along with other Storage Area Network (SAN) interfaces including Fibre Channel (FC), Fibre Channel over Ethernet (FCoE) and iSCSI for block access.
Various storage options for servers include shared external DAS, networked SAN (iSCSI, FC and now SAS) or network attached storage (NAS such as NFS and Windows CIFS file sharing). In some cases, storage is moving offsite utilizing public or private clouds and managed service provided (MSP) capabilities. Also, it is important to keep in mind that DAS does not have to mean dedicated internal storage; it can also mean external shared direct accessible storage using SAS, iSCSI or Fibre Channel in a point to point topology configuration.
