NEXENTA S VDI SOLUTIONS BRAD STONE GENERAL MANAGER NEXENTA GREATERCHINA
VDI Storage Challenge 95% of I/O is small, random writes Very challenging for a storage system End users demand low latency
NexentaStor Software-based unified storage appliance NFS, CIFS iscsi, FibreChannel NexentaStor is an operating system and storage software installed on x86 servers OpenStorage solution Running on commodity hardware iscsi, FibreChannel, SAS, AoE
Data Integrity Features 256-bit checksum Checksum stored physically separate from data Eliminated RAID write hole Data always consistent on disk Advanced RAID and three-way mirroring Self-healing
Virtualization Features Multi-protocol support Snapshot and clones Thin provisioning De-duplication VAAI support
Thin Provisioning Example: Storage pool is 4T Create 4 zvols each 2T Storage Pool 2T 2T 2T Monitor pool usage: Thin provisioning doesn t give you more physical space! 2T
Virtual Machine Management VM-consistent snapshots Fast VM cloning Create and relocate VMs Multi-hypervisor support

NexentaStor: Ideal for VDI Ability to buffer writes into sequential streams Hybrid storage pool architecture Inline compression Ability to run as a virtual machine According to a VMware architect: NexentaStor s inline De-Dupe & Compression reduce I/O from VSA to SAN/NAS by 80%
Hybrid Storage Pools Read Cache Enables outstanding price/performance Transaction log Small random writes for VDI are written to SSD to enable low latency acknowledgements to desktop user Writes are buffered, compressed, and grouped into sequential, and larger, writes to go to disk
Compression Compression done in-line at time of write Enabled by default Leverages typically idle processing power Can improve overall I/O performance Compresses only if at least 12% benefit Many algorithms supported LZJB for loss-less compression GZIP 0-9 Extensible Compression algorithm can be changed on-the-fly Affects future writes
Run as a VSA Virtual Machines NexentaStor as VSA Hypervisor Local Cache Backend Storage Package the storage as a VM on the hypervisor system As you add hypervisors to scale, you add the storage VM as well Uniform IOPs per user as you scale Deliver I/O to the hypervisor from inside the hypervisor Minimize network traffic Reduces number of slots needed on the server
