Benefits Of The Ptx1000 Router - Juniper PTX1000 Hardware Manual

NOTE: The 2 x 64-GB SSDs installed in the PTX1000 support the request vmhost snapshot
command, which creates a recovery snapshot of the currently running and active file system
partitions, and request vmhost snapshot recovery command, which recovers the primary disk
from the snapshot content stored in the backup disk. In addition, the 64-GB SSDs support
enhanced hardware resiliency through storage partitioning and redundancy.
Earlier versions of the PTX1000 have 2 x 32-GB M.2 SATA SSDs. PTX1000 routers with 32-GB
SSDs do not support the request vmhost snapshot and request vmhost snapshot recovery
commands, and do not support enhanced hardware resiliency. To determine the size of the
SSDs installed in your device, issue the show vmhost hardware CLI command. The capacity
of Disk1 and Disk2 is displayed in the output as 32.0 GB if 32-GB SSDs are installed, and the
capacity is displayed as 50.0 GB if 64-GB SSDs are installed. See the Software Installation and
Upgrade Guide for more information.
Forwarding operations are performed by the Packet Forwarding Engines, which include ASICs designed
by Juniper Networks. The custom ExpressPlus ASICs enable the PTX1000 to provide up to 2.88 terabits
per second (Tbps) of forwarding capacity. The ExpressPlus ASICs are connected to Hybrid Memory
Cubes (HMCs). These high-efficiency memory modules provide packet buffering, virtual output queue
(VOQ) memory, and improved logical system scale.

Benefits of the PTX1000 Router

Increased scalability—The PTX1000 scales to 3 Tbps in a single chassis, supporting up to 288 10-Gigabit
Ethernet interfaces, 72 40-Gigabit Ethernet interfaces, and 24 100-Gigabit Ethernet interfaces, giving
service providers the performance and scalability needed as networks grow. The purpose-built ASICs
in the PTX1000 provide enhanced packet processing for both full IP functionality and MPLS transport,
accommodating scale as traffic continues to increase and optimizing IP/MPLS transit functionality.
Space efficiency—Providing high capacity in a compact 2U form-factor, the PTX1000 meets installation
needs for peering Internet exchange points, peering collocations, central offices, and regional networks,
especially in emerging markets.
Always-on infrastructure base—The PTX1000 is engineered with full hardware redundancy for cooling,
power supplies, and forwarding, allowing service providers to meet stringent service-level agreements
across the core.
