The NetApp FAS8000 line of SAN arrays are used in highly virtualized data centers that require large amounts of...
storage space. The array comes in four models -- FAS8080EX, FAS8060, FAS8040 and FAS8020 -- that are available in all-flash and hybrid flash configurations. All-flash configurations do not use hard disk drives (HDDs), reducing latency and increasing read/write speeds. Hybrid configurations combine the performance of flash with higher-capacity and less expensive HDDs. All of the array models come with high-availability support.
The FAS8080EX is the flagship array in the NetApp FAS8000 lineup. In a SAN environment, it can support eight nodes and up to 5,760 drives for a maximum capacity of 34 petabytes (PB). It has a maximum flash pool capacity of 576 TB, a maximum all-flash capacity of 1.5 PB and a maximum memory of 1,024 TB. The FAS8080EX can also be used in a NAS environment. In this type of setup, it can fit a maximum of 17,280 drives for a maximum raw capacity of 103 PB. A NAS setup can have up to 24 nodes, a maximum flash pool capacity of 1,728 TB and a maximum all-flash capacity of 4.6 PB. A NAS setup has a maximum memory of 1.024 TB. The FAS8080EX has up to 64 Fibre Channel (FC) ports at 4 gigabits per second (Gbps), 8 Gbps or 16 Gbps; 32 Fibre Channel over Ethernet (FCoE) ports; 64 10 Gigabit Ethernet (GigE) ports; 72 1 GigE ports; and 56 SAS ports at 6 Gbps. The array also comes with a wide range of additional connectivity, such as NetApp's Unified Target Adapter 2, which provides additional FC support.
The FAS8060 can support 4,800 drives in a SAN environment, with up to 28 PB of capacity, 288 TB of flash pool capacity and 1.5 PB of all-flash capacity. It also has a maximum memory of 512 GB. In a NAS environment, the FAS8060 can have up to 14,400 drives, for a total capacity of 86 PB, a maximum flash pool capacity of 864 TB and a maximum all-flash capacity of 4.6 PB. The FAS8060 has up to 24 16 Gbps FC ports, 40 4 Gbps/8 Gbps FC ports, 24 FCoE ports, 32 10 GigE ports, 40 1 GigE ports and 40 6 Gbps SAS ports.
The FAS8040 can support 2,880 drives in a SAN setup, with a maximum capacity of 17 PB and a maximum memory of 256 GB. In a NAS setup, the FAS8040 supports up to 8,640 drives, with a maximum capacity of 51 PB. The array has a maximum memory of 768 GB. The FAS8040 has a maximum of 24 16 Gbps FC ports, 40 4 Gbps/8 Gbps FC ports, 24 FCoE ports, 32 10 GigE ports, 40 1 GigE ports and 40 6 Gbps SAS ports.
The FAS8020 can support 1,920 drives in a SAN setup, with a maximum capacity of 11.5 PB and a maximum memory of 576 GB. The array supports NAS configurations of up to 5,760 drives yielding a maximum capacity of 34 PB. The FAS8020 has 12 16 Gbps FC ports, 20 4 Gbps/8 Gbps FC ports, 12 FCoE ports, 16 10 GigE ports, 20 1 GigE ports, and 20 6 Gbps SAS ports.
The All-Flash FAS 8000 series scales to 2,880 solid-state drives and 4.6 PB of solid-state capacity per cluster. The all-flash versions use clustered Data Ontap, which includes FlashEssentials software that optimizes reads and writes, and handles inline compression and data deduplication.
All NetApp FAS arrays are built on the Data Ontap and clustered Data Ontap operating system software.
All NetApp FAS8000 models support high-availability and RAID 4, RAID 6, RAID 4 + 1 and RAID 6 + 1. The series supports most OSes such as Windows 2000/XP, Windows Server versions 2003/2008/2012, Linux, Oracle Solaris, HP-UX, Mac OS and VMware ESX.
The vendor does not publish pricing for the FAS8000 series, but based on prices for equivalent products, units may cost upward of $100,000, depending on configuration. NetApp also has a series of support tools, including a support line and online technical assistance.
