Power

Hello, I am connecting an lto 9 to a power through an ej10, I generally use an ECBY cable to connect other tape drives, is it the same in this case?

On the other hand. There is another card: EJ2B, Is there an effective change in performance if I use this one? to connect a tape?

Dear Miguel

EJ2B was a new adapter that came out just this year and provides 12Gb speed while EJ10 has been around for several years already with 6Gb speed.  You can use ECBY cable with both adapters.  

The following information is from Sales Manual of S1024 available from IBM Offering Information web site : https://www.ibm.com/common/ssi/ShowDoc.wss?docURL=/common/ssi/rep_sm/2/872/ENUS9105-_h02/index.html     Please note that S1024 Sales Manual information on EJ10 does NOT mention LTO-9.

(#EJ2B) - PCIe3 12Gb x8 SAS Tape HBA Adapter

The PCIe3 SAS Tape HBA Adapter is a high performance SAS tape controller using PCIe Gen3 12Gb x8 technology. The adapter supports external SAS tape drives such as the LTO-7, LTO-8, and LTO-9, available in the IBM 7226-1U3 Multimedia drawers or standalone tape units such as the TS2270, TS2280 single External Tape Drive, TS2900, TS3100, TS3200, or TS4300. The adapter provides four Mini-SAS HD (high density) connectors to which AE1 SAS cables such as #ECBY or AA12 SAS cables such as #ECE3 with HD narrow connectors, other cables supplied with tape devices may also be supported. A max of 4 tape drives per adapter can be attached using four AE1 or AA12 cables.

#EJ2B (full high) and #EJ2C (low profile) are electronically the same adapter with the same 57F2 CCIN, but differ in that their tailstocks to fit different size PCIe slots.
Note: Adapter uses a Mini-SAS HD narrow connector and AE1 such as #ECBY or AA12 SAS cables such as #ECE3.

Prerequisite: Firmware 1030.20.
