Product Descriptions

Sleet is a product refresh for the low-end and mid-range products in the Celerra family and will be the first implementation of the CLARiiON Fleet Storage Array on the Celerra product line. Sleet is a refresh of two product groups, the NS20/NS20FC (referred to as Sleet2) and NS40/NS40FC/NS40 for MPFS (referred to as Sleet4). Both Sleet2 and Sleet4 will retain the existing NS20/NS20FC and NS40/NS40FC front-ends and will replace the back-end CX3 based storage arrays with CX4 based storage arrays. In addition, Sleet4 will be enhanced to offer 1, 2 or 4 Blades and both Sleet2 and Sleet4 will incorporate MPFS functionality as part of the standard configuration options.
產品描述﹕
Sleet 是EMC Celerra 系列產品的中低端產品﹐它是Celerra產品線上執行EMC CLARiiOn Fleet存儲器陣列。Sleet 產品有兩組產品﹐NS20﹑NS20FC(參考Sleet2) 和NS40﹑NS40FC﹑NS40 MPFS(參考Sleet4). Sleet2和Sleet4將保留現存的NS20﹑NS20FC和NS40﹑NS40FC前端并將用CX4存儲陣列替代以CX3存儲陣列為基礎的后端。另外﹐Sleet4將增加1﹐2或4個Blade,Sleet2和Sleet4 將合并MPFS(EMC的多路径文件系统)功能作為標准配置選項的一部分。

Sleet2 will be the NS-120/NS-120FC multi-protocol offering, using the existing NS20 NAS enclosure plus Maynard control station and Fleet Nautilus (CX4-120) array (Nautilus is 6U and contains a 2U Storage Processor Enclosure with 2 SPs, a 3U Disk Array enclosure holding up to 15 FC or SATA drives and a 1U SPS Enclosure holding one or two Standby Power Supplies). Each Nautilus will be available in 3 different configurations. The base or NAS configuration will always contain a single Tomahawk I/O Module with 3 FC ports per captive CX4-120 array’s storage processor (SP). One of these FC ports is dedicated to connection to the Back End DAE drive trays while the remaining two FC ports are for Front End connectivity to 1 or 2 NAS head Blades. The second configuration is a ‘FC’ configuration and consists of two Tomahawk I/O Modules per array SP, one configured as above, the other with 4 available FC ports per SP for use with up to four non-Celerra hosts (or more via SAN) to facilitate “All in One” IP+FC storage. The FC Option Enabled configuration will require Navisphere to be used for creating RAID Groups/LUNs for Celerra and non-Celerra usage. The third configuration is an ‘iSCSI’ SP I/O configuration consisting of one Tomahawk I/O Module, configured as per the ‘NAS’ offering, and two Harpoon 2 port iSCSI I/O Modules. Each Harpoon I/O Module contains two 10/100/1000 base-T Cu iSCSI ports. A total of three I/O Modules can be present per SP in a Sleet2 product, or six I/O Modules in total.
Sleet2將由NS120﹑NS120FC 多重協義提供﹐使用現有的NS20 NAS構架加上Maynard控制工作站及EMC CLARiiON系列Fleet Nautilus(CX4-120)陣列(Nautilus 并包含一個2U的存儲處理機箱(包括2個電源)和一個3U的硬盤陣列構架(DAE)﹐DAE可以安裝15個光纖或SATA硬盤﹐另外還包括一個或者兩1U的備用電源。
每一個Sleet2 Nautilus有三個可用的不同配置:
1. 基本配置一般包括一個被CX4-120 陣列存儲處理單元控制的含一個有三個光纖通道的Tomahawk I/O模組。這三個光纖通道中有一個專用于連接后端磁盤擴展機箱﹐另外兩個光纖通道用于連接前端1到2個NAS數據轉換器。
2. 第二種配置是一個”FC(光纖通道)”配置﹐每個存儲處理器包含兩個Tomahawk I/O模組﹐每一個如配置一﹐第二個Tomahawk光纖卡含四個可用的光纖接口﹐客戶可以根據需求用于數據傳輸。FC選項配置需要通過Navisphere軟件組建RAID(独立冗余磁盘阵列) Group/LUNs(組或邏輯單元).
3. 第三種配置是”iSCSI”配置﹐包含一個Tomahawk I/O FC模組及一個Harpoon I/O iSCSI模組。
Sleet4 will be the NS-480/NS-480FC and NS40 for MPFS multi-protocol offering, using the existing NS40 NAS enclosure plus Maynard control station and Fleet Trident array (Trident comprises a 2U Storage Processor Enclosure with 2 SPs , a 3U Disk Array enclosure holding up to 15 FC drives and a 1U SPS Enclosure holding two Standby Power Supplies). Each Sleet4 Trident will be available in three different configurations. The base or NAS configuration will always contain two Tomahawk I/O Modules per SP, each with 4 FC ports. Four of these ports are dedicated to connection to the Back End DAE storage trays while the remaining four FC ports are for Front End connectivity to 1, 2 or 4 NAS head Blades. If only 2 Front End ports are being used the other two must be reserved for possible future upgrade and cannot be used
for connection to non-Celerra hosts. The second or ‘FC’ configuration adds a third Tomahawk 4 port FC I/O Module to the NAS array configuration. This enables use with up to four non-Celerra hosts per SP (or more via SAN) to facilitate “All in One” IP+FC storage. The FC Option Enabled configuration will require Navisphere to be used for creating RAID Groups/LUNs for Celerra and non-Celerra usage. The third configuration is an ‘iSCSI’ configuration consisting of two Tomahawk I/O Modules, configured as per the ‘NAS’ offering, and three Harpoon 2 port iSCSI I/O Modules. Each Harpoon I/O Module contains two 10/100/1000 base-T Cu iSCSI ports. A total of five I/O Modules can be present per SP in a Sleet4 product for a total of 10 I/O Modules per captive CX4-480 array. Sledgefleet will ship either as factory installed in an EMC 40U rack or enabled to be field installed in a customer provided 19 rack.
Sleet4是NS480﹑NS480FC及NS40提供MPFS多協義,使用現有的NS40 NAS機箱﹐加上Maynard控制工作站及EMC CLARiiON系列Fleet Trident陣列(Trident包含一個2U的存儲處理機箱(包括2個電源)和一個3U的硬盤陣列構架(DAE)﹐DAE可以安裝15個光纖或SATA硬盤﹐另外還包括一個或者兩1U的備用電源。)
每一個Sleet4 Trident包含三種不同的配置﹕
1. 基本配置包括兩個Tomahawk I/O模組﹐共8個光纖接口﹐其中4個用專用于連接后端磁盤擴展機箱﹐另外四個光纖通道用于連接前端1﹐2或4個NAS數據轉換器。
2. 第二種配置是一個”FC(光纖通道)”配置增加第三個Tomahawk 4口的光纖

Foxglove is the follow-on product to the Xblade65 (NS3-80) and is based on the next generation Common SPO platform referred to as Wildcat-S. This hardware platform is the first platform to be used by all three EMC families CLARiiON, Symmetrix and Celerra. All 3 product families will use the same CPU configuration with the only difference in memory size. By leveraging components across all the product families, the result should be a savings in terms of inventory, a reduction in unique spares, and additional product flexibility during product transition periods by offering different avenues to direct excess inventories.

Foxglove will make use of the I/O flexibility offered by using SLICs (Small I/O cards) which allow customers to choose their connectivity options from a variety of offerings that will meet their particular application and configuration needs. External I/O options provided via SLICs come in a variety of flavors. Each Foxglove xblade will support 4 SLICs with space for an additional 2 SLICs by using the Tornado I/O Module Carrier this allows 2 more SLICs in the I/O Annex slot, which will be configured as part of the base chassis offering.

The following SLICs are supported and available at GA:
4 x 4 Gb/s FC ports (Tomahawk)
4 x 10/100/1000 BaseT copper ports (Thunder Child)
2 x 10/100/1000 BaseT plus 2 x GBe optical ports (Thunder Bolt)
1 x 10 GBe port (Firestorm).

Two model families will be offered at GA:
Integrated:
- WCS Backend arrays 3 Flavors
o AUX - 1 to 2 DME - 480 drive capable
o AUXF 1 to 4 DME - 960 drive capable
