NVMe - how to add stakes in the modern information storage device

What is the NVMe -?

What is the NVMe -?

Non-volatile memory storage device (NVMe -) is extended to external access Ethernet and fiber channelNon-volatile memory storage device (NVMe) network protocolCan be faster and more efficient to connected storage devices and servers, and reduce the application server host CPU usage.

Why NVMe - is a data storage device for the future

Before there were NVMe - for your storage area network (SAN) to select the attachment types only three options:

  • ISCSI:An Internet protocol (IP) for the storage network standard, function for the small computer system interface (SCSI) instruction into TCP/IP based network.ISCSI using standard Ethernet cable, and switch to the connection to the storage devices, general situation of running speed is 1 gb/s.The speed of more than 10 gb/s to use high frequency width to achieve Ethernet card.
  • Tandem SCSI (SAS) : a point-to-point serial protocol, is used to convert the SCSI commands to the SAS cables.SAS, using a technique called SAS channel port extender, via the host bus interface card (HBA) to connect up to 128 disk drives.Connection speed options include 3 GB/s, 6 GB/s, 12 GB/s, 22.5 GB/s.
  • Fibre channel protocol (FCP) :FCP is a kind of send SCSI commands to optical fiber cable (or copper cable) agreement.Fibre channel (FC) network is called optical fiber is the cause of all switches in the network can be viewed as a single large switching.FC used light to transmit signal, so to avoid other Internet technology of electromagnetic interference (EMI) problem.The speed of FC in general will be between 1 and 128 gb/s.

Although the technology for (HDDs) hard disk and tape storage system is no problem, for solid-state drives (SSDs), has caused the performance bottleneck.SATA and PCIe SSDs everyone knows that there is no way to liberation of flash memory hidden potential.

Here introduce NVMe ─ a special design will be connecting with SSDs PCIe bus transfer agreement.Has been extended to data center, ready to integrate enterprise full flash array was born.FC non-destructive high-speed data transfer capacity and NVMe - added to the NVMe logically is the next step in the evolution oF flash array.

The online experience FlashArray / / X

Work in a self-service environment to experience the Pure FlashArray ™ / / x. management ability.To explore its advanced features, including a snapshot, facsimile, provided that even VMware integration.

NVMe - advantage

NVMe - can let the server storage devices and applications more quickly, and has a higher efficiency oF CPU usage.It will further integrate traditionally rely on direct type of storage (DAS) application in the data center.With faster Internet speed and wider bandwidth, applications can be changed to execute on Shared network storage devices.So NVMe - can provide additional data center and network integration, SAN and DAS application infrastructure oF the islands is able to use a single, high efficiency oF Shared storage infrastructure.

NVMe - can also make the external storage device in nature and DAS delays are suitable, so make the I/O than iSCSI storage device with higher efficiency, and makes the whole infrastructure more parallel, from in the modern application bottlenecks.

Why to when choosing NVMe - named Pure?

亚搏充值后支付宝能申诉吗Pure Storage ®FlashArray / / XIs the world's first Tier 0 and 100% of Tier 1 block type information storage applications to build the native NVMe storage system solutions.FlashArray / / X overall support NVMe - not only, and other Pure monopoly advantage.

  • DirectFlash ® Fabric:DirectFlash ™) is the brain behind FlashArray / / X, it solved the NAND flash memory hidden potential, make the efficiency oF NVMe - close to the DAS.
  • Evergreen ™ Storage:In the form of bottom-up design, its purpose is to support not interrupt the upgrade.You can get a modern and flexible data storage devices, no migration, downtime, no sacrifice any effectiveness.
  • Pure as - a - Service ™ :This program for both on a cloud deployment and operation of the Pure product innovation has created a single subscription.
